Yamaha YDP-88 User Manual

Make sure that your local AC mains voltage 
matches the voltage specified on the name 
plate on the bottom panel. In some areas a 
voltage selector may be provided on the 
bottom panel of the main keyboard unit near 
the power cord. Make sure that the voltage 
selector is set for the voltage in your area. A 
voltage selector is provided in some areas. 
The voltage selector is set at 220V when the 
unit is initially shipped. To change the setting 
use a “minus” screwdriver, coin, or similar 
implement to rotate the selector dial so that the 
correct voltage appears next to the pointer on 
the panel.
