Things to Try
- Verify that the battery is installed correctly.
- Charge the radio.
- Don't use the charger when the ambient temperature is
below 0° C (32° F) or above 45° C (113° F).
- Make sure the charging contacts on the radio and
charger are clean.
- Replace the battery.
- Make sure you are not in Weather or Scan mode.
- Make sure you are not trying to transmit on a receive-
only channel or transmit at the wrong power level for
this channel (see the channel lists starting on page
E-64.
- Check the battery power level; if it's low, charge the
battery before trying to transmit.
- Make sure the duration of each transmission is less
than 5 minutes.
- Try transmitting on a different channel.
- Adjust the squelch level; it is probably too high.
- Adjust the volume level; it is probably too low.
- If the radio has been exposed to water, there may be
water on the speaker. Press SPKR soft key to sound
a tone that will help remove the water. Allow the radio
to dry out.
Adjust the squelch level; it is probably too low.
Check your UIC channel settings: does the area you are
in use different channel assignments?
Make sure Weather Alert Watch is turned on.
Be sure you have channels saved into Memory.
Key beep is set to OFF. Turn Key Beep on.
- Make sure the MMSI (DSC self ID) is entered.
Reposition the radio so that nothing blocks the internal
GPS antenna from the satellite signal.
Verify that MENU/GPS/INTERNAL GPS/UNIT POWER
= ON.
The serial number is on a plate inside the battery
compartment.
Be sure there are no obstructions between the radio's
antenna and the sky. If you are inside the cabin, move
outside.
