MY HM-56 ICOM Electret Condenser Mic HAS a solder tab battery installed
inside.
Even the ICOM factory sheet about replacing the electrolytic caps shows very
clearly the battery installed. With the red wire going to the BAT+ and a
black wire going to the BAT- solder point on the printed circuit board.

There's no battery in the HM_56!.
Most of the troubles stem from leaky caps. And, by the way, if it starts
acting up, replace the electrolytic cap as soon as possible. They tart
getting leaky, a sure PCB killer. Whoever needs the schematic, holler and
you'll get it.
