Subject:  Disable Battery Saver Feature

Take apart the 23R and look at the control board.
There will be a bundle of wires tied together basically over pad #10.
It is marked, as 10.  Soder a jumper across this pad or bridge with soder,
put the radio back together.  You will find that the battery life is not near
as long with out the saver circut.

One could put in a very small switch and just disable it when needed.
