An emergency may be definedas a threat to life or property. In such instances, be sure the transceiver is on and set toCHANNEL 16. Then use the following procedure:1. Press the microphone push-to-talk switch and say “Mayday, Mayday, Mayday. Thisis , , ” (your vessel's name).2. Then repeat once: “Mayday, ” (your vessel’s name).3. Now report your position in latitude/longitude, or by giving a true or magneticbearing (state which) to a well-known landmark such as a navigation aid orgeographic feature such as an island or harbor entry.4. Explain the nature of your distress (sinking, collision, aground, fire, heart attack,life-threatening injury, etc.).5. State the kind of assistance your desire (pumps, medical aid, etc.).6. Report the number of persons aboard and condition of any injured.7. Estimate the present seaworthiness and condition of your vessel.8. Give your vessel's description: length, design (power or sail), color and otherdistinguishing marks. The total transmission should not exceed 1 minute.9. End the message by saying “OVER”. Release the microphone button and listen.10. If there is no answer, repeat the above procedure. If there is still no response, tryanother channel.8888.2.2.2.2 CALLING ANOTHER VESSEL (CHANNEL 16 OR 9) CALLING ANOTHER VESSEL (CHANNEL 16 OR 9) CALLING ANOTHER VESSEL (CHANNEL 16 OR 9) CALLING ANOTHER VESSEL (CHANNEL 16 OR 9)Channel 16 may be used for initial contact (hailing) with another vessel.However, its most important use is for emergency messages. This channel must be
FCC ID: K66GX1255SOperating ManualVertex Standard Co., Ltd.24monitored at all times except when actually using another channel.It is monitored by the U.S. and Canadian Coast Guards and by other vessels. Use ofchannel 16 for hailing must be limited to initial contact only. Calling should not exceed30 seconds, but may be repeated 3 times at 2-minute intervals. In areas of heavy radiotraffic, congestion on channel 16 resulting from its use as a hailing channel can bereduced significantly in U.S. waters by using channel 9 as the initial contact (hailing)channel for non-emergency communications. Here, also, calling time should not exceed30 seconds but may be repeated 3 times at 2-minute intervals.Prior to making contact with another vessel, refer to the channel charts in this manual,and select an appropriate channel for communications after initial contact. For example,Channels 68 and 69 of the U.S. VHF Charts are some of the channels available to non-commercial (recreational) boaters. Monitor your desired channel in advance to makesure you will not be interrupting other traffic, and then go back to either channel 16 or 9for your initial contact.When the hailing channel (16 or 9) is clear, state the name of the other vessel you wishto call and then “this is” followed by the name of your vessel and your Station License(Call Sign). When the other vessel returns your call, immediately request anotherchannel by saying “go to,” the number of the other channel, and “over.” Then switch tothe new channel. When the new channel is not busy, call the other vessel.After a transmission, say “over,” and release the microphone's push-to-talk (PTT)switch. When all communication with the other vessel is completed, end the lasttransmission by stating your Call Sign and the word “out.” Note that it is not necessaryto state your Call Sign with each transmission, only at the beginning and end of thecontact.Remember to return to Channel 16 when not using another channel. Some radiosautomatically monitor Channel 16 even when set to other channels or when scanning;see your Owner's Manual.8888.3.3.3.3 MAKING TELEPHONE CALLS MAKING TELEPHONE CALLS MAKING TELEPHONE CALLS MAKING TELEPHONE CALLSTo make a radiotelephone call, use a channel designated for this purpose, The fastestway to learn which channels are used for radiotelephone traffic is to ask at a localmarina.

Call the marine operator and identifyyourself by your vessel’s name, The marine operator will then ask you how you will payfor the call (telephone credit card, collect, etc.) and then link your radio transmission tothe telephone lines.The marine telephone company managing the VHF channel you are using may charge alink-up fee in addition to the cost of the call.8888.4.4.4.4 OPERATING ON CHANNELS 13 AND 67 OPERATING ON CHANNELS 13 AND 67 OPERATING ON CHANNELS 13 AND 67 OPERATING ON CHANNELS 13 AND 67Channel 13 is used at docks and bridges and by vessels maneuvering in port. Messageson this channel must concern navigation only, such as meeting and passing in restrictedwaters.Channel 67 is used for navigational traffic between vessels.By regulation, power is normally limited to 1 Watt on these channels. Your radio isprogrammed to automatically reduce power to this limit on these channels. However, incertain situations it may be necessary to temporarily use a higher power. See page 7(H/L key) for means to temporarily override the low-power limit on these two channels.8888.5.5.5.5 PROHIBITED COMMUNICATIONS PROHIBITED COMMUNICATIONS PROHIBITED COMMUNICATIONS PROHIBITED COMMUNICATIONSThe FCC prohibits the following communications:・ False distress or emergency messages:・ Messages to “any boat” except in emergencies and radio tests;・ Messages to or from a vessel on land;・ Transmission while on land;・ Obscene, indecent, or profane language (potential fine of $10,000).8888.6.6.6.6 NOAA WEATHER ALERT TESTING NOAA WEATHER ALERT TESTING NOAA WEATHER ALERT TESTING NOAA WEATHER ALERT TESTINGIn the event of a major storm or other appreciable weather condition requiring vesselsat sea or other bodies of water to be notified, the NOAA (National Oceanographic andAtmospheric Administration) broadcasts a 1050 Hz tone that some marine VHF radioscan detect. (Refer to Section 5.7 “NOAA WEATER ALERT” on how to use this feature.)This tone, when detected, will produce a loud beep from the radio speaker to signal thata weather alert is being broadcast.
FCC ID: K66GX1255SOperating ManualVertex Standard Co., Ltd.26In order to test this system, the NOAA broadcasts the 1050 Hz tone every Wednesday,sometime between 11 AM and 1 PM. Any marine VHF radio that can detect the weatheralert tone, may use this test to verify that this feature is functioning properly.8888.7.7.7.7 DIGITAL SELECTIVE CALLING (DSC) DIGITAL SELECTIVE CALLING (DSC) DIGITAL SELECTIVE CALLING (DSC) DIGITAL SELECTIVE CALLING (DSC)Digital Selective Calling is a semi-automated method of establishing a radio call, it hasbeen designated by the International Maritime Organization (IMO) as an internationalstandard for establishing VHF, MF and HF radio calls. It has also been designated partof the Global Maritime Distress and Safety System (GMDSS) and it is planned thatDSC will eventually replace aural watches on distress frequencies and will be used toannounce routine and urgent maritime safety information broadcasts.This new service will allow mariners to instantly send a distress call with GPS position(when connected to the transceiver) to the US Coast Guard and other vessels withinrange of the transmission. DSC will also allow mariners to initiate or receive distress,urgency, safety and routine calls to or from another vessel equipped with a DSCtransceiver.8.7.1 USCG DSC WatchThe USCG has plans to upgrade its VHF National Distress System (expected by 2005),so at the time of printing only larger vessels that are required to carry VHF DSC radioswill be able to hear your distress transmission.8.8 8.8 8.8 8.8 MARITIME MOBILE SERVICE IDENTITY (MMSI)MARITIME MOBILE SERVICE IDENTITY (MMSI)MARITIME MOBILE SERVICE IDENTITY (MMSI)MARITIME MOBILE SERVICE IDENTITY (MMSI)8.8.1 What is a MMSI?A MMSI is a nine digit number used on Marine Transceivers capable of using DigitalSelective Calling (DSC).

The marine VHF bandprovides communications over distances that are essentially “line of sight” (VHF signalsdo not travel well through objects such as buildings, hills or trees). Actual transmissionrange depends much more on antenna type, gain and height than on the power outputof the transmitter. On a fixed mount 25W radio transmission expected distances can begreater than 15 miles, for a portable 5W radio transmission the expected distance canbe greater than 5 miles in “line of sight”.8888.12 .12 .12 .12 SELECTING AN ANTENNASELECTING AN ANTENNASELECTING AN ANTENNASELECTING AN ANTENNAMarine antennas are made to radiate signals equally in all horizontal directions, butnot straight up. The objective of a marine antenna is to enhance the signal toward thehorizon. The degree to which this is accomplished is called the antenna’s gain. It ismeasured in decibels (dB) and is one of the major factors in choosing an antenna. Interms of effective radiated power (ERP), antennas are rated on the basis of how muchgain they have over a theoretical antenna with zero gain. A 3 foot, 3dB gain antennarepresents twice as much gain over the imaginary antenna. The length of the antennayou choose, however, must also be related to the size of your boat.
FCC ID: K66GX1255SOperating ManualVertex Standard Co., Ltd.28Typically a 3 foot 3dB gain stainless steel whip is used on a sailboat mast. The longer 8foot 6dB fiberglass whip is primarily used on power boats that require the additionalgain.8888.13.13.13.13 COAXIAL CABLE COAXIAL CABLE COAXIAL CABLE COAXIAL CABLEVHF antennas are connected to the transceiver by means of a coaxial cable – a shieldedtransmission line. Coaxial cable is specified by it’s diameter and construction.For runs less than 20 feet, RG-58/U, about 1/4 inch in diameter is a good choice. Forruns over 20 feet but less than 50 feet, the larger RG-8 or RG-213/U should be used forcable runs over 50 feet RG-8 should be used. For installation of the connector onto thecoaxial cable refer to the figure below.To get your coax cable through a fitting and into your boat's interior, you may have tocut off the end plug and reattach it later. You can do this if you follow the directions thatcome with the connector. Be sure to make good soldered connections.9 9 9 9 MAINTENANCE MAINTENANCE MAINTENANCE MAINTENANCEThe inherent quality of the solid-state components used in this transceiver will providemany years of continuous use. Taking the following precautions will prevent damage tothe transceiver.・ Keep the microphone connected or the jack covered at all times to preventcorrosion of electrical contacts;・ Never key the microphone unless an antenna or suitable dummy load is connectedto the transceiver.・ Ensure that the supply voltage to the transceiver does not exceed 16 VDC or fallbelow 11 VDC.・ Use only STANDARD HORIZON-approved accessories and replacement parts.In the unlikely event of serious problems, please contact your Dealer or our repairfacility.

Below are listed some data about the charts.1. VTS. Where indicated, these channels are part of the U.S. Coast Guard’s VVVVesselTTTTraffic SSSSystem.2. Alpha channel numbers, that is, channel numbers followed by the letter A (such asChannel 07AAAA) are simplexsimplexsimplexsimplex channels on the U.S.A. or Canadian channelassignments whose counterparts in the International assignments are duplexduplexduplexduplexchannels. International channels do not use “alpha” numbers. If you call the CoastGuard on Channel 16, they will sometimes ask you to “go to channel 22 Alphago to channel 22 Alphago to channel 22 Alphago to channel 22 Alpha.”This is a channel assigned to U.S.A, and Canadian Coast Guards for handlingdistress and other calls. If your radio is set for InternationalInternationalInternationalInternational operation you will go toChannel 22 instead of 22AAAA, and will not be able to communicate with the CoastGuard. To use Channel 22AAAA, your radio must be set for USAUSAUSAUSA or CanadaCanadaCanadaCanada operation,usually by a U/I/C (USA/International/Canada) control or combination of controls.Channel 22 (without an “A”) is an InternationalInternationalInternationalInternational duplex channel for port operations.Some radios indicate an “A” adjacent to the alpha channels on the display; onothers “alpha” is not indicated but the proper channel is selected based on the U/I/Csetting.3. Bridge-to-Bridge channels (for example, Channel 13) are for use by bridge operatorson intercoastal waterways and rivers. It is also used by marine vessels in thevicinity of these bridges for navigation and for communicating with the bridgeoperators. Note that a limit of 1 Watt is specified for these channels. See page xx for
