When the phone isoff-hook, the backlight will also not be activated by the <REDIAL> key.Backlight illumination also occurs during handset ringing for incoming calls. The backlighting follows the cadenceof the ringing signal (i.e., illumination when ring on and no illumination when ring off). After termination of ringing,if the call is not answered, the illumination goes off and remains off until a key is pressed or another call is received.If the call is answered, the illumination remains on for ten seconds (ten-second timer restart as a result of pressing akey) and then turns off automatically provided no other keys are pressed.Backlight illumination turns off immediately after handset is placed on cradle.2.1.5 Headset JackThe handset is equipped with a jack that is capable of mating with a 2.5 mm plug headset (optional headsetpurchased separately).

The operation of the ITAD is described separately in Section 4. The main operating modes ofthe phone are:• IDLE• TALK / handset SPEAKERPHONE / base SPEAKERPHONE• RINGING• handset HOLD / base HOLD• INTERCOM• handset PROGRAM / base PROGRAM• MEMORY REVIEWThese operating modes can be triggered by the following events:• Keys pressed on the handset• Keys pressed on the base• Receiving an incoming call from the PSTN• Replacing the handset onto the base cradle• Removing the handset from the base cradle• A timeout (where appropriate)For this section, the following are to be noted:• A <Digit> key can be any of the <1>, <2>, <3>, <4>, <5>, <6>, <7>, <8>, <9>, and <0> keys• A <Dial> key can be a <Digit> key, the <*> key, or the <#> key• When more than one function is mapped to the same key, the details of the condition to invoke thedifferent functions are described in Sections 2.1.2and 2.2.2. The user interface description is thissection references the keys as if they are independent.• When navigating the menu on the LCD, the selected menu item is highlighted by blinking the entry onthe display. However, the selected item is shown in BOLD in the user interface description below.3.1 IDLE ModeThe phone is in the IDLE mode when it is not in use by the user and there is no incoming signal from the telephoneline. In this state, the phone is on-hook and the handset operates in power conservation mode. The handset isgenerally asleep with its transmitter and receiver turned off. It will wake up periodically and power up the receiverbriefly to check for transmission from the base.The phone can go from any of its operating mode to the IDLE mode. When the <OFF> key is pressed or the handsetis placed on the base unit cradle, the phone will exit its current operating mode and go back to the IDLE modewithout sending an error beep.

In the latter case, the string may be anentry in the handset directory or base speed dial list, contents of the redial buffer (handset or base), or a caller IDrecord (handset only).During dialling, the LCD will display a “dial monitor” to indicate the dialling in progress. Starting with the first digitdialled, subsequent digits will be appended to the dial string displayed as they are dialled. The dial monitor will bedisplayed for ten seconds after each <Dial> key pressed. After ten seconds , the dial monitor will be and replaced bythe call timer on the display.Pressing <OFF> during handset dialling or <SPKR> during base dialling will return the phone to the IDLE mode.3.2.1 Live DiallingTo initiate live dialling, press either the <PHONE> on the handset or <SPKR> on the base to seize the line. Thedigits to be dialled will be sent 800 ms after the line has been seized or when the first digit is pressed, whicheveroccurs later.Besides the <Dial> keys, <FLASH>, <PAUSE> are also valid for dialling. The dial data will be stored in theappropriate redial buffer (depending where the dialling is initiated).3.2.2 RedialThe <REDIAL> key will redial the last phone number dialled when the key is pressed immediately after the phone isoff-hook. After any other keys have been dialled, <REDIAL> will no longer be valid. If the redial buffer is empty,the dialling unit will go back to the TALK with an error beep.The base and handset will each have its own independent redial buffer. The redial buffer can hold up to 32 dialleddigits. When the dialled string exceeds 32 digits, all existing data will be deleted and the redial buffer will becomeempty.TALK 2<3>TALK 2735131TALK 0:00’45. . .TALK 0:00’00<7><2>10-second delayTALK 273TALK 27<1><5><PHONE>+ Base In Use LED on

A dial monitor will be displayed to show the dialling sequence. If the phone has been inthe INTERCOM mode, the intercom will first be terminated (with a key beep sounding at the base).3.2.5 Tone/Pulse DiallingThe phone will support three dialling methods: pulse, tone (DTMF), and temporary DTMF. The pulse or tonedialling mode can be set as the default dialling method by the switch located on the base unit. The default diallingmode must be set before entering the TALK mode of operation; it is not possible to change the default dialling modewhile a call is in progress.Temporary DTMF dialling mode is only available when the default method is set to pulse. In that case, pressing the<Tone/*> key will initiate temporary DTMF dialling such that all subsequent digits dialled will be in DTMF(including <*> and <#>). Temporary DTMF dialling will continue until the phone returns to the IDLE mode, atwhich point the default pulse dialling resumes.During DTMF dialling, the <Tone/*> key will dial the DTMF <*> digit. During Pulse dialling, the <#> key has nofunction and will be ignored (even though a key-beep will be generated).3.3 TALK ModeThe TALK and SPEAKERPHONE modes on the handset and the SPEAKERPHONE mode on the base are the mainoperating modes on the phone. In all cases, the phone is off-hook and dialling is possible. In the handset TALK (orSPEAKERPHONE) mode, an RF link is available between the handset and the base and both the transmit andreceive audio paths are open for voice communication.A call timer is available on the handset during the TALK or SPEAKERPHONE mode to show the call duration.3.3.1 Caller ID with Call Waiting (CIDCW)When caller ID data is detected during a call, the call waiting alert will be sounded and the data will be displayed for20 seconds. The alert will occur on the unit or units (i.e. handset or base or both) that are active on the call.3.3.2 FlashWhen the <FLASH> key is pressed during the handset TALK (or base SPEAKERPHONE) mode, a hook flash willbe generated on the telephone line. The LCD display will be cleared during the flash operation. The <FLASH> keywill be invalid until the flash is completed. After a flash, the call timer on the handset will be reset.If <OFF> (or <SPKR> on the base) is pressed or handset is back on the cradle during flashing, the phone will returnto the IDLE mode.Flashing from handset:JOHN SMITH1-212-345-67893.3AM+ call waiting alertcaller ID with call waiting<FLASH > TALK 0:00’00TALK0:25’15

However, the record will not be storedinto the handset caller ID log.Where there is a phone number available in the incoming caller ID data, the number will be in one of two formats –direct dial number (DDN) or dial number (DN). For DDN, all the digits in the data will be displayed withoutmodifications, only adding “-“ in the appropriate places as separators (e.g. 12123456789 becomes 1-212-345-6789while 3456789 becomes 345-6789). For DN, the number of digits displayed for the phone number is determinedbased on matching the area code of the incoming call (where available from the local telephone company) with thearea code(s) configured in the phone. If the area code matches the home area code, the call is assumed to be localand the seven-digit phone number is displayed (e.g. 2123456789 becomes 345-6789). Alternatively, if the area codematches one of the local area codes, the complete ten-digit phone number is displayed (e.g. 2123456789 becomes212-345-6789).

However, it will be possible to program the handset directoryduring the base SPEAKERPHONE mode, or program the base speed dial list during the handset TALK (orSPEAKERPHONE) mode.After <PGM> is pressed to enter the handset PROGRAM mode, only the <SELECT>, < ►>, <◄ >, <#>, <*> and<PHONE> keys will be valid. Once the phone is in the PROGRAM mode, there is a 20-second time-out for keyinput.Pressing <SELECT> or <PGM> at the end of the programming sequence will complete the operation. If there are noinput errors, the new data will be stored into memory and the phone will return to the IDLE mode with a confirmationbeep. Otherwise, in the event of an input time-out or a programming error, an error beep will be sounded and thephone will go to the IDLE mode.If there is an incoming ring or page during the PROGRAM mode, the ringer or paging alert will be sounded but theprogramming operation can continue. The display of the caller ID data associated with the incoming call will bepostponed until the current programming sequence is completed or if <PHONE> is pressed. In the latter case, thephone will abort the programming and go to the TALK mode.3.8.1 Program Handset DirectoryStart of programming:Each directory entry includes a name and the associated telephone number. The maximum number of directoryentries is 50 (less if there are longer entries). If memory is full, a MEMORY FULL message will be displayed alongwith an error beep and phone will go to the IDLE mode.The name can be up to 16 alphanumeric characters. The alphanumeric characters can be entered via the<Dial> keys;additional keys that are acceptable during the name entry phase include <SELECT>, < ►>, <◄ >, and <PHONE>(< ►> is not valid until at least one character has been entered).

After the redial buffer is cleared, the phone will go back to theIDLE mode with a confirmation beep.3.10 Voice Announce (Option)The voice announce feature provides an audio announcement of an incoming call over the base and handsetspeakerphone. The announcement is based on the incoming caller ID data and can be one of three types: user-recorded names, pre-recorded generic announcements, or numeric announcement.When the voice announce feature is enabled, the phone number portion of the caller ID data determines which typeof announcement is made. When the number of the calling party matches one of the entries in the handset directory(the matching is based on the last seven digits of the phone number), the voice tag associated with the entry will beplayed. The voice tag is recorded by the user to identify the directory entry (generally the name will be used). Itmay be recorded when the entry is created, or added subsequently.If no match for the caller number can be found in the handset directory, the caller ID data indicates a private orout-of-area caller, or the call has been intercepted by the Privacy Manager at the local telephone company (whereavailable), a standard announcement that corresponds to “Unknown Caller”, “Private Caller” or “PrivacyManager, press ‘1’ to continue”, respectively, will be made. These three standard announcements are pre-programmed on the phone.16042735131<REDIAL>5-sectimeout<SELECT>+ confirmation beep16042735131<REDIAL>< 5 sec<REDIAL>

The answering device includes three (optionally four) mailboxes for storingincoming messages. The ITAD can be operated locally, using keys available on the base unit, or remotely, viaDTMF key inputs when calling in from another telephone.The ITAD provides storage for up to 18 minutes of recording of incoming messages and memos (with silencecompression) or 99 messages in total.With the exception of turning on the answering machine and accessing remote operation, all other functionsdescribed in the following subsections are available only when the ITAD has been activated. The main modes ofoperation for the ITAD include answering incoming calls, recording memos, reviewing stored messages, andconfiguring settings.When the ITAD is connected to an incoming call, various non-ITAD keys or events can cause the current answeringmachine function to terminate and the ITAD to release any connection to the telephone line:• If <PHONE> on the handset or <SPRK> on the base is pressed, the phone will go into the TALKmode.• If <INT.COM> on the handset is pressed (either to initiate an intercom, or in response to a page fromthe base), the phone will go into the INTERCOM mode.• If a parallel telephone set goes off-hook, the phone will go into the IDLE mode.For all remaining other ITAD functions, it will be possible for the phone to operate in the TALK (or handsetSPEAKERPHONE), handset HOLD, handset PROGRAM, or MEMORY REVIEW mode even when the ITAD isin-use. However, phone operations that involve the use of the base speakerphone will cause the answering machinefunction to terminate:• If <SPRK> on the base is pressed, the phone will go into the base SPEAKERPHONE mode.• If <INT.COM> on the handset is pressed (either to initiate an intercom, or in response to a page fromthe base), the phone will go into the INTERCOM mode.4.1 ITAD Local OperationA number of keys on the base unit are provided for local access to ITAD functions. These keys include:• <ANSWER ON/OFF>• <MEMO>• <MENU>• <SELECT>• <TIME/SET>• <MAILBOX #1>• <MAILBOX #2>• <MAILBOX #3>• <MAILBOX #4> (option)• <ERASE>

There is also a no-activitytimeout (20 seconds unless otherwise noted). In either case, a termination beep will be sounded to indicate currentoperation is terminated.4.1.1 Activating the Answering MachineAfter power up, the answering machine will be automatically turned on and is available to answer incoming calls. Itcan subsequently be deactivated and re-activated by the user. When the answering machine is off, all <ITAD> keyswill be ignored except for <ANSWER ON/OFF>.Activating the ITAD:Deactivating the ITAD:If the answering machine is turned on and configured to allow incoming messages but memory is full (see Section4.1.9.3), the ITAD will be deactivated automatically. In this case, the Answer LED will remain lit and the 7-segmentdisplay will indicate memory full by alternately blinking Fand the total number of new messages.4.1.2 Answering Incoming CallsWhen the ITAD is activated, an incoming call that has not been answered after a pre-determined number of rings willbe routed to the answering machine. The ITAD will answer the call and play an outgoing message (OGM) to greetthe caller. The answering machine can be configured to allow the caller to leave a message after the greeting, or justplay the announcement. For announce-only, the OGM will be played twice to ensure the caller does not miss themessage.There is a different OGM associated with normal and announce-only answering. Furthermore, the user can select tohave a personal greeting or use the standard (pre-recorded) greeting in each case. When there are no custom OGMthat has been recorded, the ITAD will use the default standard greeting.The standard greetings are:<ANSWER ON/OFF> Answeringmachine on+ Answer LED onITAD off<ANSWER ON/OFF> Answeringmachine off+ Answer LED offITAD on

If the answeringmachine is turned on while the phone is in the RINGING mode, the ring counter that is used to determine when theITAD answers the call will start its count from the time the <ANSWER ON/OFF> key is pressed.While the OGM is being played, the user can answer the incoming call by pressing <PHONE> on the handset or<SPRK> on the base. The ITAD will terminate the announcement and the phone will go into the TALK mode.Alternatively, if a parallel telephone set goes off-hook, the announcement will also be terminated and the phone willgo into the IDLE mode.If another call is received (call-waiting signal detected) while the answering machine is recording an incomingmessage, the recording will continue and the first call will remain connected.Even when the answering machine is deactivated, it will answer an incoming call after ten rings. The ITAD willprovide a “Please enter your security code” announcement to allow access to remote ITAD operations.4.1.3 Privacy Screening (Option)The privacy screening feature allows the answering machine to intercept calls that come in from unknown orblocked callers. Only models equipped with four mailboxes may offer this optional feature. When this feature isenabled (and the ITAD is not set to announce-only answering), the phone uses the caller ID information todetermine which calls will be routed to the answering machine automatically. Since the CID information is receivedbetween the first and second rings, the phone will ring once before the call is answered by the ITAD. The caller willhear the pre-recorded privacy screening OGM as follows (this OGM is separate from the normal or announce-onlyOGM):If the caller leaves a message, it will be placed in mailbox #4.If the privacy screening option is not available or if the feature is disabled, operation of mailbox #4 (whereavailable) will be identical to the remaining three mailboxes.Hello, I'm unable to answeryour call right now.

Unless otherwise directed by the caller, the message will be stored in mailbox#1. The caller can select a different mailbox (i.e. mailbox #2 or #3) by entering “*2” or “*3” (DTMF only) at theremote telephone during the OGM playback.Recording will be terminated when one of the following is detected:• silence in excess of six (6) seconds• three (3) consecutive busy tones or continuous busy tone for five (5) seconds from the telephone line• “*0” (DTMF tone) from the telephone line• <PHONE> on handset or <SPRK> on base is pressed• a parallel telephone set goes off-hookThe maximum allowable length of an incoming message is four (4) minutes. If the maximum length is reached or ifmemory becomes full during recording, recording will also be terminated automatically.Extended period of silence at the end of the recording will be removed in the stored message. If the incomingmessage is less than two seconds long, it will not be regarded as a valid message. Otherwise, it will be stored intomemory along with a time- and day-stamp and the appropriate ITAD message counters (i.e., the total number ofmessages in all the mailboxes and the number of new messages in the selected mailbox) will be incremented by one.The updated number of messages will be indicated on the 7-segment display.When the recording is terminated, the ITAD will release the telephone line connection. The phone will stay off-hookand go into the TALK mode if the user has pressed the <PHONE> or <SPRK> key to intercept the call; in all othercases, the phone will go into the IDLE mode.4.1.5 Call-ScreeningWhen the ITAD answers a call and call-screening is enabled, the user will be able to hear the voices (to and from thecaller) on the base speakerphone (assuming the volume level is sufficient loud). The user can choose to talk to thecaller anytime after the ITAD has answered the call by one of the following: pressing <PHONE> on the handset,removing the handset from the cradle, pressing <SPKR> on the base, or picking up an extension phone. The ITADwill halt its operation and release its connection to the line (the handset, base or extension phone that has picked upthe call will be connected instead).

During the recording, the 7-segmentdisplay will indicate the recording time in seconds. When the duration exceeds 99 seconds, the display will flash 99.There is no silence detection during memo recording. The recording will be terminated only when the user presses a<Mailbox> key or when the length of the memo reaches four (4) minutes. If memory becomes full during recording,recording will also be terminated automaticallyIf the memo is less than two seconds long, it will not be regarded as a valid message. Otherwise, it will be storedinto memory along with a time-and day-stamp and the appropriate ITAD message counters (i.e., the total number ofmessages in all the mailboxes and the number of new messages in the selected mailbox) will be incremented by one.The updated number of messages will be indicated on the 7-segment display.4.1.7 Reviewing Messages / MemosWhen the ITAD is not actively engaged in an operation (e.g. playing OGM, recording incoming message or memo,or changing configuration), the 7-segment display will blink a count to indicate the total number of new messagesand memos stored in the answering machine. (The display will indicate a steady 0if there are no new messages inany mailboxes.) All messages stored (new or old) can be reviewed by selecting to play back messages in a mailbox.At the start of recording playback, the ITAD will announce the number of messages available in the selectedmailbox. Generally, only the new messages in the mailbox will be played during message review. However, if thereare no new messages in the mailbox, the ITAD will play back the old messages. A message will be considered oldafter it has been reviewed (played back completely or if it has been skipped through by the user deliberately). Theplayback sequence for the messages will be first-in-first-out (FIFO). During playback, the 7-segment display willindicate the number of the current message. The count display will blink if the message is new, or it will be onsteady otherwise.

In addition, the calling telephone must supporttouch-tone signalling in order to transmit he DTMF tones required to access the various options.The functions that are available via remote operations include activating/deactivating the answering machine,reviewing (and deleting) messages, recording memo, and modifying personal greetings.During remote operation, entering "*0" on the touch-tone keypad of the remote telephone or pressing a <Mailbox>key on the base unit will terminate the current operation and the ITAD will disconnect the line. The ITAD will alsoexit remote operation and hang up after a 20-second, no-activity timeout.4.2.1 Accessing Remote OperationTo access the ITAD operations available from a remote telephone, the user must call in and dial the correct securitycode when the ITAD answers the call and plays the appropriate greeting or prompt.When the “#” key is dialled during the announcement, the announcement will be muted for two seconds to allow thecaller to dial the two-digit security code. It will also be possible to enter the security code during the recording of anincoming message. In this case, the caller must dial the “#” key to interrupt the recording and dial the security code.The recording will be stopped after a valid security code has been entered, and the recorded incomplete message willbe deleted.The ITAD will disconnect the line automatically after three attempts to dial the correct security code have failed(dialling a single "#" will not be regarded as an error entry). If “#*”, “*#”, “##” or “**” is entered, the first digit isignored. The two-second muting time will be counted from the second key.4.2.2 Voice Menu for Remote ControlThe ITAD provides two pre-recorded voice menus to help the user navigate the remote operation options. A simplevoice menu list the key sequence for accessing the most commonly used operations, while an advance voice menu isavailable to list the key sequence for the remaining operations available. The simple voice menu will be played ineight seconds after the caller has entered a valid security code and the ITAD announced the number of new messagesor anytime the caller dials “*5”.

If memory becomes full during recording, recording will beterminated automatically.If the memo is less than two seconds long, it will not be regarded as a valid message. Otherwise, it will be storedinto memory along with a time-and day-stamp and the appropriate ITAD message counters (i.e., the total number ofmessages in all the mailboxes and the number of new messages in the selected mailbox) will be incremented by one.The updated number of messages will be indicated on the 7-segment display.If memory is already full or the total number of messages is 99 when “*8” is dialled, no new memos will be accepted.In that case, the ITAD will provide a "Memory full" announcement.4.2.5 Reviewing MessagesThe caller can select to review the messages in a desired mailbox by dialling the function key sequence thatcorresponds to the desired mailbox (“#1”, “#2”, and “#3” for mailboxes 1, 2 and 3 respectively; “#8” can be used toaccess mailbox 4 where the privacy screening option is available). At the start of recording playback, the ITAD willannounce the number of messages available in the selected mailbox. Generally, only the new messages in themailbox will be played during message review. However, if there are no new messages in the mailbox, the ITAD willplay back the old messages. A message will be considered old after it has been reviewed (played back completely orif it has been skipped through by the user deliberately). The playback sequence for the messages will be first-in-first-out (FIFO).

It is used to transfer both audio (voice) and data between the base and handset. There are a total of 30 RFchannels available for communication. Only one channel may be selected as the active channel at any instant, thoughthere are provisions to select to a different active channel when there are perceived interference on the currentchannel.5.1 RF Link DataData is transmitted over the RF link between the handset and the base unit in packets. A fixed frame format is usedto provide for the simultaneous transmission of three logical channels – voice, control and frame synchronisationdata. The voice channel contains analog voice signals that have been are digitised using 32 kbps ADPCM dataencoding; the control data are generally operational commands from the base to handset and vice-versa; and theframe synchronisation data facilitates reception of the packet over the RF link. For improved security, the voice andcontrol data is scrambled prior to transmission; descrambling must be done at the receiving end prior to furtherprocessing of the voice and control data.When the phone is in the IDLE mode, the base and handset will listen for data transmission from the other relating tothe initiation of the PHONE, RINGING, PROGRAM or INTERCOM mode. If the handset is away from the cradle,the handset will be in the power-conservation mode of operation, in which the on-board electronics are essentially“asleep” but will wake up periodically to check for incoming data transmitted from the base. The handset will detectcommands sent from the base within one (1) second (maximum ringing delay), while the base will detect commandssent from the handset within 200 ms (maximum on/off-hook delay).5.2 Security CodeAll data communication over the RF link will include a security code as required by FCC Part 15. When a frame isreceived over the RF link, the security code is contained in the packet (part of the control channel) will be verifiedbefore any data is processed. This prevents the handset from receiving commands from another base unit and vice-versa.The handset and base units will use an identical, 24-bit security code that is factory-configured. The security code isstored in the non-volatile memory on both units and cannot be modified by the user.5.3 RF Channel SelectionIn order for the handset and base unit to communicate over the RF link, the selection of the active channel must besynchronised between the two units. An active channel is initially selected during the PDLci MK3 initialisationprocess. If the RF link subsequently degrades during operation, recovery involves the selection of a newcommunication channel that is automatically initiated and no user-intervention will be required.Regardless of the phone’s operating mode, both the handset and base units are constantly monitoring the quality ofthe active communication channel. Even when the handset is in power-conservation mode, the base is periodicallytransmitting link-status messages to the handset to verify the integrity of the RF link. The handset will also respondperiodically to the link-status message to provide feedback to the base unit.When the link is operational, the assessment of the channel quality is done based on the error rate detected on theincoming frames. While the voice channel is transparent, the control channel includes an error control mechanism.

VTECH ENGINEERING CANADA LTD.TITLE Internal Product SpecificationMODEL PDLci MK3 - 900MHz Single-Line Digital Cordless Telephonewith Caller ID, Speakerphone & Base KeypadReference: PRC 00FN Revision: 0 Page: 80 of 92This document is proprietary to VTECH ENGINEERING CANADA LTD.49371.DOCSpecifications are preliminary and are subject to change without noticeIf the error rate of the incoming data is beyond an acceptable threshold, either the handset or the base canindependently initiate a channel change.The best channel out of the remaining 29 channels will be selected as the new channel. (If no improved channel canbe identified, the units will remain on the existing active channel and scanning for a new channel will begin againafter a brief delay.) If a new channel is selected and a link can be maintained in spite of a degraded link condition,the change to a new channel will occur in a co-ordinated manner. Otherwise, the handset and base unit will attemptthe link recovery procedure.5.4 Handset Out of Range DetectionWhen the RF link is broken between the handset and the base, the handset will provide both a visual and audiblealert. The audible alert consists of two separate alarm tones, and each will be sounded for 30 seconds for totalduration of 60 seconds. The LCD will continue to display the OUT OF RANGE message until either the RF link isre-established or the battery becomes dead.If the handset was in the TALK mode when out-of-range was detected, and the link is re-established during thesounding of the alarm (i.e. within 60 seconds), the handset will resume in the TALK mode and the conversation willbe continued. Otherwise, the line will be dropped and the phone will return to the IDLE mode.5.5 Link RecoveryThe RF link between the handset and base can be broken because the handset has gone out-of-range or because ofthe active channel selection at the handset and base are out of synchronisation. In either case, the units will attemptto re-establish communication with each other. The base unit will continuously transmit packets on the differentchannels while the handset scans all the channels for an incoming packet from the base. To prevent a deadlockcondition, the rates with which the units cycle through the channels are different between the handset and the base.With the handset scanning at a significantly faster rate than the base, the handset will have multiple chances ofreceiving the base transmission and responding to it before the base changes to transmit on another channel.During the link recovery procedure, the LCD will continuously display the CHANNEL SEARCHING message. Whenthe link is re-established successfully, the LCD will display the FOUND CHANNEL x message for five (5) seconds,where “x” identifies the (newly selected) active channel.detectout-of-range+ Handset Out-of-Range alarm 1OUT OF RANGE OUT OF RANGEOUT OF RANGE 30 sec+ Handset Out-of-Range alarm 2 + Handset error beep30 sec

There are no connectorsattached to the battery pack. When fully charged, the battery will provide a minimum of seven (7) hours of operationin the TALK mode, three (3) hours of operation in handset SPEAKERPHONE mode, or seven (7) days of operationin the IDLE mode before requiring recharge. The battery pack will recharge automatically whenever the handset isplaced in the cradle of the base unit. (The Charge LED will lit to indicate the battery is being charged.) In addition,the battery pack can also be recharged via a compatible remote charger.6.2 Low Battery IndicationThe phone will provide both audible and visual warning when low battery condition in the handset is detected. Whenthe handset determines that the battery is running low, the LCD will display the icon. In addition, the LCDwill display a BATTERY LOW message for fifteen (15) seconds and an audible alert will be made if the handset is ina non-IDLE mode. The low battery alarm will be repeated every three (3) seconds for up to five times during theactive call or operation. The user may press any key during the fifteen-second alarm interval to suppress the messagedisplay and audible alert. Except for the continued display of the low-battery icon, the remaining low-batteryindication will not be repeated until the phone goes off-hook or begins another operation after returning to the IDLEstate.6.3 Spare Battery ChargerThe PDLci MK3 is equipped with a separate battery charger in the base unit that can be used to charge a sparebattery pack (optionally purchased). The Spare Battery LED will illuminate when a battery pack is placed in thecharger. The spare battery pack can also be used as backup power source for the base unit, as described in Section6.4.6.4 POTS Mode OperationThe PDLci MK3 provides a mode of operation that emulates a plain old telephone set (POTS). It allows the baseunit to maintain operation during AC power outages or any situation where the AC power is removed from the baseunit when there is a charged battery installed in the spare battery compartment.To indicate the phone is operating in POTS mode, the handset LCD will display a CHECK AC POWER message andthe base Spare Battery LED will blink.+ Handset low battery alarmdetect low batteryTALK 0:03’45 BATTERY LOW

The handsetpower supply may be interrupted if the battery is physically removed from the compartment. Alternatively, thehandset battery may be completely drained of its charges. In the base unit, the power supply is interrupted when ACpower is unavailable.In either case, the PDLci MK3 provides the capability to recover from the power interruption. Operation in thehandset SPEAKERPHONE or TALK mode will be maintained through a brief power interruption (up to 125 ms induration) to the base unit. In all other instances, the affected unit will be reset to allow the handset and base unit tore-establish RF communication and resume operation in the IDLE mode. The critical information that must beavailable to allow quick restoration of RF communication is the security code and the last active RF channel. Onboth the handset and base unit, this information will be restored directly from non-volatile memory.All directory entries, redial information, caller ID log and area code(s) configuration will be retained through apower interruption to the handset. However, the ringer type, volume, and receiver volume settings will be reset tothe default values when the power resumes. Similarly, the speakerphone volume setting will be reset after a powerinterruption to the base unit.For the ITAD, all messages in the mailboxes, user-recorded announcements as well as configuration for theanswering machine will be retained through a power interruption. After the power resumes, the ITAD will have abrief initialisation period (the -- indication will flash on the 7-segment display) before normal ITAD operation canresume (phone operation is available during this time). In addition, the real time clock will need to be reset by theuser (the [L indication will show on the 7-segment display to remind the user).
