Have you tried charging the batteries?

Re 396t

Yes the battery are fully charged

Not to sound flippant, but are the batteries in correctly polarity wise? I've done that more times than I can count..

 

[9z4kds]

Yes they are properly in the right order .

it is

+ -
- +
+ -
i also put those 2300 in backwards what with the negative side looking like a duracell top.
the only thing i could think of is that a diode is burned out.
might be best to send to uniden for service.

That came to mind also but I am sure I did put in the battery correctly ,but I agree the diode could have gone

Try 3 new alkaline AA batts--don't forget to flip the switch so they don't charge. That way you are sure it's not the batteries or charge system.
