Problem
I can't hear anything
from the speaker.
The sound is muffled
or the volume is low.
Noise comes out of
the speaker all the
time
I can transmit, but no
one can hear me.
I'm not getting hazard
alerts.
The display flashes,
and I don't know why.
Where can I find my
radio's serial number?

Things to Try
Adjust the squelch level; it is probably too high.
Clear water from the speaker grill.
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.
The channel number on the display will flash if
the radio is in a watch mode or in scan mode.
Try turning off scanning, Weather Alert Watch,
Triple Watch, or Dual Watch (see page E-8).
The serial number is on a plate inside the
battery compartment.
