[Kenwood] TM732a "Battery"

[Jim Miller]

OK, Is there a battery inside the TM732a?  Mine is a 1992 version and I have never changed the battery and it is acting strange.  It is NOT losing it's memories.  This has all happened in about 2 months.  The front panel lights don't.  The mic buttons don't work except for the top row.  It transmits just fine (full power) one minute and the next minute it looks like it is but no movement on the wattmeter, sometimes turning it off and back on "fixes" the transmit problem.  Does the battery need changed?  Where is it?  Is it a "watch" type you can get a replacement for at the drugstore?

Thanks and 73, de Jim KG0KP
