I replaced the lithium batteries in my four Yamaha TX81Z FM synthesizers.
Since I was in there anyway I replaced the solder-terminal batteries with
battery holders for future battery replacement ease.

After the work I tested all of the units; three powered up as normal, but one
says "Program Me" on the display for a brief time. You can scroll it through
the standard factory programs. Did I happen to just lose the user programs
on this (no big deal if so)? Perhaps from the battery being disconnected for
too long. Does this indicate that perhaps the battery is not working in the
circuit?

Any comments are appreciated.
