Double Check your Power Source/Supply and wiring for voltage dfrops under current load. When the voltage drops to about 11-11.5 volts on the back two pins of the radio during TX it give a low battery indicator. It could be a corroded connection in the line I have seen that drop the voltage just enough to Bleep Bleep!
Get a good volt meter and trace the power path to ground while keying and you probably will find the problem.
It is annoying when things look good but I have always been able to find something. Had a bad fuse holder once,spade lug on the battery,bad splice connector etc.
I have about 40 CDM1550s in my fleet.
