Replacement battery for the DSP-2232?
 

Hi,

I got a call from a friend about replacing the battery for the
DSP-2232. The manual describes it as a 3 volt Lithium battery, with a
useless part number of BT1. He was wondering about a part number so
as not to have to disconnect and open the unit twice. Anybody have
some info on this?

TIA,

Alan
