Problem
Things to Try
I can’t hear anything
from the speaker.
Adjust the squelch level; it is probably too high.
Noise comes out of the
speaker all the time
Adjust the squelch level; it is probably too low.
I can transmit, but no
one can hear me.
Check your UIC channel settings: does the area
you are in use different channel assignments?
I’m not getting hazard
alerts.
Make sure Weather Alert Watch is turned on.
The display flashes,
and I don’t know why.
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 6).
Where can I find my
radio’s serial number?
The serial number is on a plate inside the
battery compartment.
