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.
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 x You cannot transmit while in scan mode. x You must have two or more channels in memory to start a scan. x To save a channel into memory, select the 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.
Using the radio in weather mode x You cannot transmit while in weather mode. x To enter weather mode, press WX-MEM. x 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.
CALL 1W/2.5 W 1W/2.5 W 1W/2.5 W Using Your Radio x An arrow on the left side indicates the current selection. x 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.
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.
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.

POSITION REQUEST AND REPLY Requesting another station’s position (POS Request) Anytime you need to know where another boat currently is—to find your boating partners, to respond to a request for assistance, etc.—you can send a position request to their radio: 1.
Enabling automatic position reply If you want the radio to automatically transmit your current position whenever it receives a position request, you can enable automatic position reply. Most boaters activate automatic position reply for safety reasons or because they subscribe to a marine towing service.
3. To cancel standby and return to the mode your radio was in, press any button. DISABLING AUTOMATIC CHANNEL SWITCHING If you are involved in a bridge-to-bridge call, you may not want the radio to automatically switch channels when it receives a DSC call. In cases like this, you can disable automatic channel switching.
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: x Properly support the weight of the radio, approximately 2.2 pounds or 1.0 kilograms.
CONNECTING THE RADIO To operate correctly, your radio requires two electrical connections: x providing it with power from the boat’s electrical system x 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 50 Ω...

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.
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: x If the antenna has been damaged, you should not transmit except in the case of an emergency.
