Generally, if you don't want to lose memories, you should replace the
battery while the radio is operating.

???????

Personally, I wouldn't replace anything in any radio with the power on.
Suppose he dropped the battery and it shorted out something on the board. I
bet he would be wishing he used common sense and turned the rig off. The
battery is a CR2032 3V available at any Radio Shack or camera store. If it
is soldered to the board, you can salvage a holder of an old motherboard and
use it. But please, turn the power off no matter wat. The TS50 is too good
a radio to damage. Memory channels can be replaced a lot cheaper than a
radio can.
