So I bought a Poly 61 and came home to test it out. It ran okay but one of the voices had a weird envelope. Opened it up to check for battery leakage and yes there was some so I removed the battery and now nothing! I just get a stuck screen with no buttons responding at all? No sound either. I just cleaned the battery leakage area with alcohol. Should the Poly 61 run fine without the battery?
Also how would I go about repairing the damage done by the battery never done a trace repair job before.
