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 ashes,
and I don’t know why.
The channel number on the display will ash if
the radio is in a watch mode or in scan mode.

Triple Watch, or Dual Watch (see page 6).

The serial number is on a plate inside the
battery compartment.
