I have a funny problem with my EM-2000. Sometimes when turning on the keyboard, everything is set, the accompainment, and the right hand tone is not even with the left hand tone, I mean, it sounds a little off tune.

Usually, I give CPR... I turn ON/Off the keyboard several times, and sometimes I hit it and kick it, and then, after 10 minuted it feels much better... and return to normal. It usually happens when the keyboard is cold.

Any suggestions? Anybody with a similar problem?

Doesnt sound good. Have it checked by a dealer.
