Problem
The power LED on the
charger doesn't turn on.
The radio won't transmit.
I can't hear anything from
the speaker.
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?
E-50
Things to Try
- Don't use the charger when the ambient
temperature is below 0° C (32° F) or
above 45° C (113° F).
- Make sure the charging contacts on the
radio and charger are clean.
- Replace the battery.
Make sure you are not in Weather or Scan
mode.
Make sure you are not trying to transmit on
a receive-only channel or transmit at the
wrong power level for this channel (see the
channel lists starting on page E-23).
Check the battery power level; if it's low,
charge the battery before trying to transmit.
Make sure the duration of each transmission
is less than 5 minutes.
Adjust the squelch level; it is probably too
high.
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-7).
The serial number is on a plate inside the
battery compartment.
