Disabling Buttons—Panel Lock
 
By using the Panel Lock function, you can disable the buttons 
with the exception of certain operations. This is a convenient 
way to prevent buttons from being pressed inadvertently, 
changing the settings.
When the panel is locked, the following operations can be 
performed.
- Play using the piano sound

Before switching the power on, turn the 
volume all the way down.

Adjust the volume.
 
Playing the keyboard now produces a Piano 1 sound.
It will not be possible to switch to another sound.
Switching the power off and back on again releases the 
panel lock and returns the MP-500 to its usual state.
 
You can set Panel Lock in Step 3 above by turning on the 
power while holding down any Tone button other than the 
[Piano 1] button. In that case, you can play using only the 
tone of the button that was pressed.
