Message GPS Data OK Meaning The radio is receiving valid GPS data. The radio is not receiving valid GPS data: check the GPS status screen and the GPS connection. The radio has been unable to receive valid GPS data for at Input least four hours; it can no longer track your position. You need Position to manually input your position (see Setting the GPS position manually on page 14). Battery Low The battery voltage output is too low (below 10.5 VDC).
Normal mode with Triple or Dual Watch If you activate Triple Watch while operating in normal mode, the radio checks channels 16 and 9 every two seconds; with Dual Watch turned on, the radio only checks channel 16. The radio will not check channels 16 or 9 while you are actively transmitting; it waits until your transmission is finished and then checks the channels. Press and hold 16/9-TRI (on the radio or the microphone) for two seconds to turn Triple/ Dual Watch on or off.
In scan mode, you can get the following information from the display (some indicators will not always be displayed). Using the radio in scan mode xx You cannot transmit while in scan mode. xx You must have two or more channels in memory to start a scan. xx To save a channel into memory, select the channel, then press and hold WX-MEM for two seconds. Memory will show on the display. xx To remove a channel from memory, set the radio to that channel, then press and hold WX-MEM for two seconds.
Scan mode with Triple or Dual Watch If you activate Triple Watch while operating in scan mode, the radio checks channels 16 and 9 every two seconds, then goes on to scan the next channel; with Dual Watch turned on, the radio only checks channel 16. Press and hold 16/9-TRI (on the radio or the microphone) for two seconds to turn Triple or Dual Watch on or off. (To change between Triple or Dual Watch, see page 13.
Using the radio in weather mode xx You cannot transmit while in weather mode. xx To enter weather mode, press WX-MEM. xx Weather mode can filter out alerts that do not affect your location if the location code (FIPS code) of the alert is entered in your radio (see page 13). If you have no FIPS codes programmed into your radio, the radio will notify you of all alerts in any area. xx To turn off the radio’s alert tone, press any button.
CALL ENT 1W/2.5 W ENT 1W/2.5 W ENT 1W/2.5 W Using Your Radio xx An arrow on the left side indicates the current selection. xx Press CHANNEL UP on the radio or the microphone to move up a line in the menu; if you are at the top line in the menu, the cursor jumps to the bottom of the menu. xx Press ENT-1W/25W to choose the selected item. xx Press CHANNEL DOWN on the radio or the microphone to move down a line in the menu; if you are at the bottom line of the menu, the cursor jumps to the top of the menu.
While listening to a channel, adjust the SQUELCH knob until the noise is filtered out and you can only hear the transmission. If you switch to a channel with a lot of noise or with a weak transmission, you may need to adjust the squelch level again. ## NOTE: Setting the squelch level too high may prevent you from hearing weaker transmissions. If you are having difficulty hearing a transmission, try setting the squelch level lower.
Some channels (for example, channels 13 and 67) limit the power of transmission to 1 Watt so that there is less interference between boaters attempting to use the channel at the same time. If you switch to one of these channels, the radio changes back to 1 Watt automatically. See the channel lists beginning on page 37 for a list of power-restricted channels. Choosing Triple Watch or Dual Watch In Triple Watch mode, the radio briefly checks channels 16 and 9 every two seconds.

Press and hold CALL-MENU to display the normal menu. 2.
INSTALLING THE HARDWARE MOUNTING THE RADIO Your radio can sit at any angle in the mounting bracket so it can easily accommodate the best location. First, determine the best place to mount the radio. For optimum performance, find a location that can: xx Properly support the weight of the radio, approximately 2.2 pounds or 1.0 kilograms. You may need to use some type of anchor with the mounting screws to hold the radio, depending on the surface. xx Keep the battery leads as short as possible.
CONNECTING THE RADIO To operate correctly, your radio requires two electrical connections: xx providing it with power from the boat’s electrical system xx connecting a VHF-FM marine antenna to the antenna connector Power Supply Requirements VHF Antenna Requirements Male PL-259 connector Nominal 13.8 VDC power supply with a negative ground (10.5 VDC to 16.0 VDC). 50 Ω impedance Power leads should be kept as short as Minimum 3 foot, 3 dB rated antenna for possible.
CONNECTING THE ACCESSORY CABLE Use the accessory cable to connect the radio to a GPS receiver, a GPS chartplotter, and an external speaker. The wiring diagram below shows the connections for each accessory. ACCESSORY CABLE WIRES CONNECTS TO...
After 4 hours, the audible alert sounds again if no coordinates are received and the GPS is connected. After 23.5 hours, the radio deleted the current coordinates and displays Input GPS. See page 14 to manually set the GPS coordinates. Configuring the GPS If the radio is receiving valid GPS data, it will automatically set the clock to your local time based on the GPS location.
CONNECTING TO AN EXTERNAL SPEAKER You can use an external speaker to monitor the radio from a different part of your boat or in a noisy environment. If you adjust the VOLUME-PWR knob on the radio, it will also adjust the external speaker volume. Your radio supports an external speaker with the following specifications: xx Minimum impedance of 4 Ohms xx Minimum power handling of 10 Watts 1. Connect the BLACK wire of the accessory cable to the GROUND WIRE of your external speaker. 2.
MAINTENANCE AND TROUBLESHOOTING Due to its rugged design, your radio requires very little maintenance. However, it is a precision electronic instrument, so you should follow a few precautions: xx If the antenna has been damaged, you should not transmit except in the case of an emergency. A defective antenna may cause damage to your radio. xx You are responsible for continued FCC technical compliance of your radio. xx You should arrange for periodic performance checks with your dealer.
Problem Things to Try Make sure your GPS receiver is correctly connected (see Connecting to a GPS receiver, page 30). I’m not getting any GPS data on my display. Make sure your GPS receiver is working properly. I’m not getting any hazard alerts. Check to make sure the FIPS codes in your radio include your current location (see Using FIPS codes for weather alerts on page 13). Check to make sure the FIPS codes in your radio were entered correctly (see Using FIPS codes for weather alerts on page 13).
