KX3 with internal batteries won't drive or control KXPA100, KX3 needs 12 volts to work right

[Robert Sands]

Heading says it all. My internal batteries are good for 10 plus volts and 5
watts output from KX3. When joined with the KXPA100 there is no function of
the power control over the amp. Power setting max is 5 Watts and no amp
output. With 12 volts applied, power control works well up to 110 watts.
All is well but I would like to use the internal battery source and be able
to make the twins work as with 12 V. Setup error? Advise please.

Booting up KX3 and KXPA100 with external DC and then unplugging the external DC from KX3, KX3 continues to drive KXPA100. Booting up KX3 with internal battery and KXPA100 with external DC source do not allow KX3 driving KXPA100. It looks KX3 firmware decides to bypass KXPA100 when it determines booted up with internal battery while PAMODE is ON.
