First of all I hope I’m in the right forum.
I purchased 4 Motorola T80 walkie-talkies last year and they worked perfectly until recently.
Now, one of the units won’t transmit. When I press the transmit button, it emits a continuous beep and the channel number is flashing. The other units work fine on the same channel. The battery is fully charged.
I couldn’t find anything in the manual or online.
Does anyone have any idea what it could be?
