Uniden UM725 Radio Owner’s Manual
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, do not transmit except in an emergency situation.
Doing so may cause further radio damage.
x You are responsible for continued FCC technical compliance of your radio.
x Arrange for periodic performance checks with your Uniden dealer.
Problem Things to Try
The radio won’t turn on.
If you turn the radio on immediately after turning it off, the
power may not turn on due to data saving. Wait for few
seconds and turn it on again.
Check the fuse.
Check polarity.
Check the line voltage (10.5V to 16V).
The radio won’t transmit.
Make sure you are not in Weather mode.
Make sure you are not trying to transmit on a receive-only

minutes.

Adjust the squelch level; it is probably too low.
