FCC license forms, including applications for ship (506) and land station licenses can be downloaded via the Internet at www.fcc.gov/forms. To obtain a form from the FCC, call (888) 225-5322. RADIO CALL SIGN Currently the FCC does not require recreational boaters to have a Ship Radio Station License. The USCG recommends the boats registration number and the state to be used. CANADIAN SHIP STATION LICENSING You may need a license when traveling in Canada. If you do need a license contact their nearest field office or regional office or write: Industry Canada Radio Regulatory Branch Attn: DOSP 300 Slater Street Ottawa, Ontario Canada, KIA 0C8 GX1280S Page 5 FCC NOTICE NOTICE Unauthorized changes or modifications to this equipment may void compliance with FCC Rules. Any change or modification must be approved in writing by STANDARD HORIZON. NOTICE This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: - Reorient or relocate the receiving antenna. - Increase the separation between the equipment and receiver. - Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. - Consult the dealer or an experienced radio/TV technician for help. Page 6 GX1280S GETTING STARTED ABOUT VHF RADIO The radio frequencies used in the VHF marine band lie between 156 and 158 MHz with some shore stations available between 161 and 163 MHz. The marine VHF band provides communications over distances that are essentially "line of sight" (VHF signals do not travel well through objects such as buildings, hills or trees). Actual transmission range depends much more on antenna type, gain and height than on the power output of the transmitter. On a fixed mount 25W radio transmission expected distances can be greater than 15 miles, for a portable 5W radio transmission the expected distance can be greater than 5 miles in "line of sight". SELECTING AN ANTENNA Marine antennas are made to radiate signals equally in all horizontal directions, but not straight up. The objective of a marine antenna is to enhance the signal toward the horizon. The degree to which this is accomplished is called the antenna's gain. It is measured in decibels (dB) and is one of the major factors in choosing an antenna. In terms of effective radiated power (ERP), antennas are rated on the basis of how much gain they have over a theoretical antenna with zero gain. A 3 foot, 3dB gain antenna represents twice as much gain over the imaginary antenna. Typically a 3 foot 3dB gain stainless steel whip is used on a sailboat mast. The longer 8 foot 6dB fiberglass whip is primarily used on power boats that require the additional gain. GX1280S Page 7 COAXIAL CABLE VHF antennas are connected to the transceiver by means of a coaxial cable ­ a shielded transmission 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. For runs over 20 feet but less than 50 feet, the larger RG-8X or RG213/U should be used for cable runs over 50 feet RG-8X should be used. For installation of the connector onto the coaxial cable refer to the figure below. Adapter 1/16'' 3/4'' 3/4'' 1 1/8'' 1/8'' 3/8'' 5/8'' To get your coax cable through a fitting and into your boat's interior, you may have to cut off the end plug and reattach it later. You can do this if you follow the directions that come with the connector. Be sure to make good soldered connections.

The mode changes from USA to International to Canadian with each press of the [WX] key. 2. "USA" will be displayed on the LCD for USA mode, "INTL" will be displayed for International mode, and "CAN" will be displayed for Canadian mode. 3. Refer to the VHF MARINE CHANNEL CHART (page 63) for allocated channels in each mode. 6.6 NOAA WEATHER CHANNELS 1. To receive a NOAA weather channel, press the [WX] key from any channel. The transceiver will go to the last selected weather channel. 2. Turn the CHANNEL selector knob on the radio or [UP( )] / [DOWN( )] keys on the microphone to select a different NOAA weather channel. 3. To exit from the NOAA weather channels, press the [WX] key. The transceiver returns to the channel it was on prior to a weather channel. Page 24 GX1280S 6.7 NOAA WEATHER ALERT In the event of extreme weather disturbances, such as storms and hurricanes, the NOAA (National Oceanic and Atmospheric Administration) sends a weather alert accompanied by a 1050 Hz tone and subsequent weather report on one of the NOAA weather channels. When the Weather Alert feature is enabled (see section 8.5 WX ALERT), the transceiver is capable of receiving this alert if the following is performed: 1. Program NOAA weather channels into the transceiver's memory for scanning. Follow the same procedure as for regular channels under section 6.15. 2. Press the [SCAN] key once to start memory scanning or hold down the [SCAN] key during memory scanning to start priority scanning. 3. The programmed NOAA weather channels will be scanned along with the regular-programmed channels. However, scanning will not stop on a normal weather broadcast unless a NOAA alert is received. 4. When an alert is received on a NOAA weather channel, scanning will stop and the transceiver will emit a loud beep to alert the user of a NOAA broadcast. 5. Press the [WX] key to stop the alert tone and receive the weather report. NOTE If the [WX] key is not pressed the alert tone will be emitted for 5 minutes and then the weather report will be received. NOTE The Weather Alert feature is also engaged while the transceiver is receiving on one of the NOAA weather channels. 6.8 NOAA WEATHER ALERT TESTING In the event of a major storm or other appreciable weather condition requiring vessels at sea or other bodies of water to be notified, the NOAA (National Oceanographic and Atmospheric Administration) broadcasts a 1050 Hz tone that some marine VHF radios can detect. (Refer to Section 6.7 "NOAA WEATER ALERT" on how to use this feature.) This tone, when detected, will produce a loud beep from the radio speaker to signal that a weather alert is being broadcast. In order to test this system, the NOAA broadcasts the 1050 Hz tone every Wednesday, sometime between 11 AM and 1 PM. GX1280S Page 25 6.9 EMERGENCY (CHANNEL 16 USE) Channel 16 is known as the Hail and Distress Channel. An emergency may be defined as a threat to life or property. In such instances, be sure the transceiver is on and set to CHANNEL 16. Then use the following procedure: 1. Press the microphone push-to-talk switch and say "Mayday, Mayday, Mayday. This is , , " (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 magnetic bearing (state which) to a well-known landmark such as a navigation aid or geographic 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 other distinguishing 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, try another channel. 6.10 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 monitored 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 of channel 16 for hailing must be limited to initial contact only. Calling should not exceed 30 seconds, but may be repeated 3 times at 2-minute intervals. In areas of heavy radio traffic, congestion on channel 16 resulting from its use as a hailing channel can be reduced 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 exceed 30 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 Page 26 GX1280S some of the channels available to non-commercial (recreational) boaters. Monitor your desired channel in advance to make sure you will not be interrupting other traffic, and then go back to either channel 16 or 9 for your initial contact. When the hailing channel (16 or 9) is clear, state the name of the other vessel you wish to 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 another channel by saying "go to," the number of the other channel, and "over." Then switch to the 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 last transmission by stating your Call Sign and the word "out." Note that it is not necessary to state your Call Sign with each transmission, only at the beginning and end of the contact. Remember to return to Channel 16 when not using another channel. Some radios automatically monitor Channel 16 even when set to other channels or when scanning. 6.11 MAKING TELEPHONE CALLS To make a radiotelephone call, use a channel designated for this purpose, The fastest way to learn which channels are used for radiotelephone traffic is to ask at a local marina. Channels available for such traffic are designated Public Correspondence channels on the channel charts in this manual. Some examples for USA use are Channels 24, 25, 26, 27, 28, 84, 85, 86, and 87. Call the marine operator and identify yourself by your vessel's name, The marine operator will then ask you how you will pay for the call (telephone credit card, collect, etc.) and then link your radio transmission to the telephone lines. The marine telephone company managing the VHF channel you are using may charge a link-up fee in addition to the cost of the call. 6.12 OPERATING ON CHANNELS 13 AND 67 Channel 13 is used at docks and bridges and by vessels maneuvering in port. Messages on this channel must concern navigation only, such as meeting and passing in restricted waters. Channel 67 is used for navigational traffic between vessels. GX1280S Page 27 By regulation, power is normally limited to 1 Watt on these channels. Your radio is programmed to automatically reduce power to this limit on these channels. However, in certain situations it may be necessary to temporarily use a higher power. See page 20 (H/L key) for means to temporarily override the low-power limit on these two channels. 6.13 PROHIBITED COMMUNICATIONS The 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). 6.14 DUAL WATCH (TO CH16) 1.

GX1280S Page 29 6.18 VOICE SCRAMBLER If privacy of communications is desired, a CVS2500 voice scrambler (VS) can be installed in the transceiver. Contact your Dealer to have a CVS2500 installed. Refer to the section 8.9 VOICE SCRAMBLER to program the voice scrambler. 1. Turn on the transceiver. 2. Select a channel that was programmed for scrambler mode ("VS" will appear on the LCD). If a channel is not set for the voice scrambler, the display will be as shown in the illustration at the right ("VS" will disappear from the LCD). If a voice scrambler is canceled temporarily in the "SETUP" menu, the display will be as shown in the illustration at the right. 3. Monitor the channel before transmitting. 4. Transmit the voice message. The signal sent will be scrambled. 6.19 RESETTING THE TRANSCEIVER'S MICROPROCESSOR Resetting the microprocessor restores the initial, factory supplied conditions in the transceiver. These are called the default conditions. To reset the microprocessor, first turn the transceiver off. Then while pressing the [WX] and [SCAN] keys, turn the transceiver on. The default conditions are: No channels in the SCAN memory. Channel 16 will be selected when the transceiver is turned on. WX channel 01 will be recalled when the [WX] key is pressed. Key beep will be on. NOTE Resetting the microprocessor will not erase DSC MMSI and Directory Call Waiting information. Page 30 GX1280S 7 DIGITAL SELECTIVE CALLING 7.1 GENERAL WARNING This radio is designed to generate a digital maritime distress and safety call to facilitate search and rescue. To be effective as a safety device, this equipment must be used only within communication range of a shorebased VHF marine channel 70 distress and safety watch system. The range of signal may vary but under normal conditions should be approximately 20 nautical miles. Digital Selective Calling is a semi-automated method of establishing a radio call, it has been designated by the International Maritime Organization (IMO) as an international standard for establishing VHF, MF and HF radio calls. It has also been designated as part of the Global Maritime Distress and Safety System (GMDSS). It is planned that DSC will eventually replace aural watches on distress frequencies and will be used to announce routine and urgent maritime safety information broadcasts. This new system allows mariners to instantly send a distress call with GPS position (when connected to the transceiver) to the US Coast Guard and other vessels within range of the transmission. DSC will also allow mariners to initiate or receive Distress, Urgency, Safety, Routine, POSITION REQUEST, POSITION SEND, and Group calls to or from another vessel equipped with a DSC transceiver. 7.2 DSC SCAN When the radio is shipped from the factory it is programmed so CH70 (the DSC channel) is scanned at all times. A selection is provided in the SETUP MENU to disable the DSC SCAN. Turning off DSC SCAN will disable the radio from receiving DSC calls (i.e.: Distress Call, Individual Call, All Ships Call, and Position Requests). If you want to use any of the functions the selection must be left ON. To Change DSC SCAN Method: 1. Press and hold down the [CALL/SET] key until "RADIO SETUP" menu appears. 2. Turn the CHANNEL selector knob to select "DSC SETUP" menu. 3. Press the [ CALL/SET ] key, then select "DSC GX1280S Page 31 SCAN" with the CHANNEL selector knob. 4. Press the [CALL/SET] key. 5.
