Charger problem: ERR BC3 in VFO B, d=002 in VFO A

[WA7OP]

I was using Lithiums and when they died I installed fresh NiMH and then worked the Baltic on 5 watts. Then I enabled the charger for 8 hours. The next day the charge setting in the menu displays ERR BC3 in VFO B, d=002 in VFO A. This locks the display with those messages until the KX3 is power cycled.The  FW is v1.5. The NiMH cells are not charging. Also the clock won't set and displays 45:85:85. I found the ERR BC3 was encountered by some one else running older FW but there was no definitive resolution. Can anyone provide some ideas for a solution?

Tnx, Scott wa7op

Works as expected now! This is problem is now resolved by a more serious reseating of the KXBC3 board (as is suggested in the manual). Also, kit builders should take care with the wire routing.
Elecraft has certainly got a jewel here. They rock! And, many thanks to Rich, AC7, for responding.
