5 INSTALLATION Flush Mount Figure 1.2 Mounting Bracket Figure 1.3
6 Physical Mounting: Select a mounting location where the unit is easily accessed. Mount the unit in the desired position using the provided Trunnion mount or flush mounting kit. See Figures 1.2 and 1.3. Power supply wiring: CAUTION: Make sure that the provided fuse holder is installed on the power cord between the radio and the power source, and that the proper sized fuse (7.5A) is installed. Use a 12 volt +30%/-10% (10.8 to 15.6VDC) DC power source for proper operation. Do not exceed 16.0 volts. Direct connection to the battery is recommended. Connect the heavy red wire, with in-line fuse installed, to the positive (+) terminal and the heavy black wire to the negative (-) terminal. Negative ground is required for the USA/Canada version of the SEA 157S. CAUTION: If the polarity of the power wires is reversed (Black to positive, Red to negative), and power is accidentally applied to the radio, the in-line fuse will blow. It is possible that damage could also occur to some internal components. Application of voltages greater than 16.0 volts will produce the same result. (Refer service to a qualified technician.) Antenna wiring: Use only the best available 50 ohm coaxial antenna cable and connectors. The antenna must be vertically polarized. Check the antenna system for less than 1.5:1 VSWR with an in-line wattmeter before final installation. The antenna cable PL-259 connector should be tightly fastened to the antenna connector on the back of the unit. All antenna connections should be carefully protected from the weather.

After selecting the distress condition and manually entering the position, press and hold the distress key for 5 seconds to send the distress call. The radio will wait for an acknowledgment from the coast station and automatically resend the DSC message approximately every 4 minutes if a coast station does not respond. During this time the display will show the time until next transmission and the “WAITING FOR ACK” status. At any time you may press the ENT key to resend the distress call immediately. NOTE: All DSC functions are disabled unless a valid DSC ID (MMSI number) is programmed in the unit. See “Set DSC ID” (Paragraph21.8). 15.0 TRANSMITTING A DSC CALL To access the DSC Calling functions, press FUNC-8. This will bring up the primary DSC menu. The menu selections are used for reviewing received calls, programming station IDs and transmitting the various DSC message formats. Most calls will conform to one of the five predefined formats which have a simplified calling procedure: Routine Individual calls, Alternate Channel proposal, Distress Relay calls and All Ship calls for the purpose
18 of warning. For all other calls that do not fit one of these predefined categories, the operator may compose a call using the Build Class A operation. Class A formats allow all call types to be generated, including geographic area calls, group calls, non-voice (fax and data) calls, position request and polls. The 16 # key may be used to abort the DSC call at any point in the process and return to the Primary Radio Display. When a DSC call is made that does not require the receiving station to send an acknowledgment, such as an “ALL SHIP” call, the radio switches to the selected voice communications channel immediately after the call is sent. When an Individual call is sent the unit will wait for an acknowledgement to be received before switching to the selected channel. While waiting for an acknowledgement to a DSC call the radio will alternately display “DSC CALLING” and “WAITING FOR ACK”. The call may be resent immediately by pressing the ENT key. Once an acknowledgement is received the radio will switch to the selected voice channel and the display will show “ABLE” or “UNABLE”, depending on the response received, until the user takes action such as keying the radio or changing channels. 15.1 INDIVIDUAL DSC CALL A routine Individual DSC Call is used to address another station and propose a working voice channel. This type of call requires the receiving station to send a response. Start by selecting the desired working channel you want to use. Press FUNC-8 to access the DSC Menu. Using the rotary control to move the cursor, select individual DSC Call menu item, then press ENT. The user-programmable Individual DSC Calling list will be displayed with the last station called selected. Use the rotary control to select the desired station. Press ENT to initiate the DSC call.
19 15.2 GROUP DSC CALL A routine Group Call is used to address a group of stations and propose a working voice channel. This type of call requires no response from the receiving stations. Start by selecting the desired working channel you want to use. Press FUNC-8 to access the DSC Menu. Using the rotary control to move the cursor, select Group Call menu item, then press ENT. The user-programmable Group Calling listwill be displayed with the last station called selected. Use the rotary control to select the desired station. Press ENT to initiate the DSC call. 15.3 PLACING A TELEPHONE CALL WITH DSC The DSC call system may be used to set up a telephone call through an appropriately equipped coast station. To initiate a phone call, press FNC-8 to access the DSC Menu. Using the rotary control to move the cursor, select the DSC Phone Call menu item, then press ENT. The most recently contacted coast station’s DSC ID and phone number will be displayed. If this information is correct, press ENT to initiate the call. To change the coast station’s DSC ID, use the rotary control to move the cursor to the DSC ID field and then press ENT. Select either “Direct Entry” or select the DSC ID from the predefined Coast Station DSC ID list. Enter a new DSC ID if required. Press ENT to complete the entry. To change the telephone calling number, use the rotary control to move the cursor to the phone number field, then press ENT. Select either “Direct Entry” or select a phone number from the predefined phone number list. Enter the new phone number if required. Press ENT to complete the entry. Press the ENT key to transmit the request to the coast station. If the coast station is able to accept the request, the radio will change to the working channel assigned by the coast station.
20 16.0 RECEIVING A DSC CALL The SEA 157S constantly monitors CH70 using a dedicated watch receiver. When a DSC call is received, the radio will beep quickly 2 times every 5 seconds. This alert tone will continue for 2 minutes or until the user presses a keypad key or the PTT switch, at which time the alert tone will cease. The display will indicate the type of call received, the source of the call (either the name or DSC ID) and any other information that is relevant to the type of call. When a Distress Call is received the radio will sound an alternating 2-tone distress alarm. The alert tone will continue for 2 minutes or until the user presses a keypad key or the PTT switch, at which time the alert tone will cease. The display will indicate that a distress call has been received. When an All Ships or Geographic Call is received the radio will beep once and switch to the voice channel specified by the calling station. The display will show “ALL SHIP” or “GEO CALL” while on the selected channel. The display will revert to its normal operating mode when the channel selector is changed or a key is pressed. When an Individual Call is received additional action may be taken automatically, depending on the setting of the DSC ACK mode setup menu. If an automatic reply has been selected, then the acknowledgment will be sent and the radio will switch to the voice channel selected by the calling station. If the manual reply mode is selected then the radio will display “ABLE” and beep once per second. Use the "ABLE" setting, or select “UNABLE” using the rotary control, then press the ENT key to transmit the acknowledgment. The radio will switch to the channel selected by the calling station if “ABLE” was sent, or remain on the current working channel if “UNABLE” was sent.
