Re: Battery charger

The battery is shorted out. You will need to replace it.

I canot get the tranceiver top transmit. When you push the traansmit button it justs beeps once. Signed Randy

This can sometimes be the sign of a low or bad battery. Try swapping your battery with a known good unit and see if the problem persists. If you do find swapping batteries solves the problem, then you will need to troubleshoot if it is the battery or the charger which needs attention. Clean your contacts on the battery and charger with a pencil eraser to ensure good contact, and always have the radio turned off when charging. Batteries typically last approx. 18-24 months before needing replaced.

I have a TK-280 and when i put it on the charger the red charging light comes on the starts flashing red after about a min. I am on the fire dept. where i live and kinda need it charged up. I wanted to...

  • Couple things this could be.
  1. First thing is to make sure the radio is seated properly in the charger and that all the contacts are making contact and not dirty.
  2. The other thing this could be is that the battery is bad. Or in the least the capacity for the battery is extremely bad and not reliable.
  3. If the contacts look good and it's sitting on the charger proper than you will need to get another battery pack. Sorry.

  • Hope this helps and thank you for using FixYa.

TK 380 diplays "FPU OLD!"

This means that you need an older version of software. to program the radio. When it comes to Kenwood the newer version software will not program the older FPU Version radios.

Kenwood th - 79E playing up

Charger should be able to power the radio at 'EL' level, if NOTHNG happens, I'd say charger is on the blink.
