Had mine for about a year, npc on radio display and battery's (x3) wouldn't work with it, but work in my drills. I suspect water got into it as that's the only change in circumstances. I opened up the rear compartment, sprayed the bottom battery (old style) contacts as a short would suggestions the radio that the battery was flat. With compressed air and a towel, dried out the interior. It now works. I have issues with the volume not knob, similar issue I believe (water Ingress).
