[Elecraft] KX-3 won't turn on with batteries

[ncelarry at scicable.com]

I got my new factory built KX-3 last week. I just installed new eneloop 
pro NI-MH batteries and the radio will not turn on using the batteries. 
Using a power supply I changed the charger settings per the manual, when 
I try to close out of the menu I get a batt err message.

Yes the charger was installed at the factory.

I also tried a new set of Energizer Max still will not turn on.

All batteries are new and the voltage is as it should be.

I also checked battery plug in the radio it was tight.

I did check polarity several times.

Any ideas???

TIA
