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.
1/16''
3/4''
1 1/8''
Adapter
3/4''
1/8''
5/8''3/8''
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.

5 CONTROLS AND INDICATORS
NOTE
This section defines each control of the transceiver. See Figure 4 for location of controls. For detailed operating instructions refer to chapter 6 of this manual.
5.1 CONTROLS AND CONNECTIONS
POWER SWITCH/VOLUME CONTROL
Turns the transceiver on and off as well as adjusts the audio volume. To turn the transceiver on press and hold this knob until the LCD turns on. To turn it off, press and hold this knob until the LCD turns off. When the power is turned on, the transceiver is set to the last selected channel.
Secondary Use
When the transceiver is turned on while the [SCAN] and [WX] keys are held down, the internal microprocessor is reset. This clears the memory and all user-programmed settings, such as scan memory, and priority scan assignments. This condition is known as the default condition, the same as when shipped from the factory. For a list of these defaults, see the section 6.18 Resetting the Transceiver’s Microprocessor.
NOTE
Resetting the microprocess will not erase the DSC MMSI and the Individual Directory Call information.
SQUELCH CONTROL (SQL
Adjusting this control clockwise, sets the point at which random noise on the channel does not activate the audio circuits but a received signal does. This point is called the squelch threshold. Further adjustment of the squelch control will degrade reception of wanted transmissions.
CHANNEL SELECTOR KNOB
Rotary knob used to select channels and to choose menu items (such as the DSC menu, radio setup and DSC setup menu). The [UP()] / [
DOWN()] key on the microphone can also be used to select channels
and menu items.
Secondary Use
While holding down the [SCAN] Key and turning the CHANNEL selector knob, you can confirm memory channels for scanning.

6 BASIC OPERATION
6.1 RECEPTION
1. After the transceiver has been installed, ensure that the power supply and antenna are properly connected.
2. Press and hold the VOL/PWR knob until the radio turns on.
3. Turn the SQL knob fully counterclockwise. This state is known as “squelch off”.
4. Turn up the VOL/PWR knob until noise or audio from the speaker is at a comfortable level.
5. Turn the SQL knob clockwise until the random noise disappears. This state is known as the “squelch threshold.”
6. Turn the CHANNEL selector knob to select the desired channel. Refer to the channel chart on page 62 for available channels.
7. When a message is received, adjust the volume to the desired listening level. The “BUSY” indicator in the LCD is displayed indicating that the channel is being used.
6.2 TRANSMISSION
1. Perform steps 1 through 6 of RECEPTION.
2. Before transmitting, monitor the channel to ensure it is clear.
THIS IS AN FCC REQUIREMENT!
3. Press the PTT (push-to-talk) switch. The “TX” indicator on the LCD is displayed.
4. Speak slowly and clearly into the microphone.
5. When the transmission is finished, release the PTT switch.
NOTE
This is a noise-canceling microphone. The oval slot on the bottom of microphone should be positioned within 1 inch (2.5 cm) from the mouth for optimum performance.
6.3 TRANSMIT TIME - OUT TIMER (TOT)
When the PTT switch on the microphone is held down, transmit time is limited to 5 minutes. This limits unintentional transmissions due to a stuck micro­phone. About 10 seconds before automatic transmitter shutdown, a warning beep will be heard from the speaker(s). The transceiver will automatically go to receive mode, even if the PTT switch is continually held down. Before trans­mitting again, the PTT switch must first be released and then pressed again.
GX1280S Page 23
6.4 SIMPLEX/DUPLEX CHANNEL USE
Refer to the VHF MARINE CHANNEL CHART (page 63) for instructions on use of simplex and duplex channels.
NOTE
All channels are factory-programmed in accordance with FCC (USA), Industry Canada (Canada), and International regulations. Mode of op­eration cannot be altered from simplex to duplex or vice-versa.
6.5 USA, CANADA, AND INTERNATIONAL MODE
1. To change the modes, hold the [16/9] key and press the [WX] key. 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.

GX1280SPage 24
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
2. Then repeat once: “Mayday,
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.
, , ” (your vessel’s name).
” (your vessel’s name).
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
GX1280SPage 26
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).

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.

10.3 TROUBLESHOOTING CHART
SYMPTON
Transceiver fails to power up.
Transceiver blows fuse when connected to power supply.
Popping or whining noise from the speaker while engine runs.
Sound is not emitted from the external speaker.
Receiving station re­port low transmit power, even with transceiver set to HI power.
“HI BATTERY” or “LO BATTERY” message is appeared when the power is turned on.
Your position is not displayed.
PROBABLE CAUSE
No DC voltage to the transceiver, or blown fuse.
Reversed power wires.
Engine noise.
Accessory cable.
Antenna.
The power supply volt­age is too high or too low.
Accessory cable.
Setting of the GPS navigation receiver.
REMEDY
a. Check the 12VDC battery con-
nections and the fuse.
b. The VOL/PWR knob needs to
be pressed and held to turn the radio on.
Check the power cable for DC volt­age, or replace the fuse (6A 250V). Make sure the red wire is con­nected to the positive (+) battery post, and the black wire is con­nected to the negative (-) battery post. If the fuse still blows, con­tact your Dealer.
Reroute the DC power cables away from the engine. Add noise suppressor on power cable. Change to resistive spark plug wires and/or add an alternator whine filter.
Check the connections of the ac­cessory cable.
Have the antenna checked or test the transceiver with another an­tenna. If the problem persists, con­tact your Dealer for servicing.
Confirm that the connected power supply voltage is not 17 volts or lower than 10 volts. Confirm that the generator has not malfunc­tioned.
Check the accessory cable con­nection.
Some GPS use the battery ground line for NMEA connection.
Check the output signal format of the GPS navigation receiver. This radio requires NMEA0183 format with GLL sentence as an output signal. If the GPS has a baud rate setting make sure to select 4800 and parity to NONE.
GX1280S Page 61
11. CHANNEL ASSIGNMENTS
Tables on the following columns list the VHF Marine Channel assignments for U.S.A. and International use. Below are listed some data about the charts.
1. VTS. Where indicated, these channels are part of the U.S. Coast Guard’s Vessel Traffic System.
2. Alpha channel numbers, that is, channel numbers followed by the letter A (such as Channel 07A) are simplex channels on the U.S.A. or Cana­dian channel assignments whose counterparts in the International as­signments are duplex channels. International channels do not use “al- pha” numbers. If you call the Coast Guard on Channel 16, they will some­times ask you to “go to channel 22 Alpha.” This is a channel assigned to U.S.A, and Canadian Coast Guards for handling distress and other calls. If your radio is set for International operation you will go to Chan­nel 22 instead of 22A, and will not be able to communicate with the Coast Guard. To use Channel 22A, your radio must be set for USA or Canada operation, usually by a U/I/C (USA/International/Canada) con­trol or combination of controls. Channel 22 (without an “A”) is an Inter- national duplex channel for port operations. Some radios indicate an “A” adjacent to the alpha channels on the display; on others “alpha” is not indicated but the proper channel is selected based on the U/I/C set­ting.
3. Bridge-to-Bridge channels (for example, Channel 13) are for use by bridge operators on intercoastal waterways and rivers. It is also used by marine vessels in the vicinity of these bridges for navigation and for communi­cating with the bridge operators. Note that a limit of 1 Watt is specified for these channels. See page 27 for additional information.
4. The S/D column on the chart indicates either S (simplex) or D (duplex). Simplex means transmitting and receiving on the same frequency. Only one party at a time can talk, unlike a telephone. Be sure to say “over” and release your microphone push-to-talk switch at the end of each trans­mission. Duplex operation involves the use of one frequency for trans­mitting and a separate frequency for receiving. On channels specified as duplex on the charts, correct mode of operation is established auto­matically by your radio when you select a channel; you cannot change the mode. And you still must release the push-to-talk switch after each transmission in order to listen to the radio.
