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:
• 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.
• You are responsible for continued FCC technical compliance of your radio.
• You should arrange for periodic performance checks with your dealer.
Problem
Things to Try
The radio won’t power on.
Check the power connections.
Check the fuse.
Check the master battery switch and branch circuit that
connect to the radio.
The radio won’t transmit.
Make sure you are not in weather or scan mode.
Make sure you are not trying to transmit on a receive-only
channel (see the channels and frequency tables beginning
on page 50).
Make sure you are transmitting at the correct power level for
this channel (see the channels and frequency tables
beginning on page 50).
Make sure the duration of each transmission is less than 5
minutes.
Noise comes out of the speaker
all the time
Adjust the squelch level; it is probably too low.
I can’t hear anything (no volume)
from the speaker.
Adjust the squelch level; it is probably too high.
I can transmit, but no one can
hear me.
Check your UIC channel settings (see Setting the UIC

The display flashes, and I don’t
know why.
The display will flash if the radio is in a watch mode or in
scan mode. Try turning off scanning, Weather Alert Watch,
