Discussion about the Korg PolySix synthesizer

I just found out that the New battery that was installed is a slightly 
lower voltage, a 2032 lithium

It should be 3.2 Volts? Correct?

I messed with the Reset Adjuster to no avail. The main problem was the 
sound reverting back to Bank One , Sound A every 20 minutes or so. 
Would a lower voltage battery be causing the problem?

Thanks
Joe
