Batboard

Afternoon, I have a APX6500LI that will beep then lose audio after it has not received any transmissions in the last 4 hrs. We power it off then back on and works for another 4 hrs since the last reception.

Have this tied into a US Digital ATX via the speaker output on the accessory connector.

I have looked through the CPS for anything with a 240min setting, but UTL so far. Any help is appreciated.

Thanks!
Chris
