Setting Up

Power Requirements

Although the PSR-450 will run either from an AC adaptor or batteries, Yamaha 
recommends use of an AC adaptor whenever possible.  An AC adaptor is more 
environmentally friendly than batteries and does not deplete resources.

■ Using an AC Power Adaptor

mended by Yamaha) to the power supply jack.

For battery operation the PSR-450 requires six 1.5V “D” size, R20P (LR20) or 
equivalent batteries. (Alkaline batteries are recommended.)  When the batteries 
need to be replaced, the volume may be reduced, the sound may be distorted, and 
other problems may occur. When this happens, turn the power off and replace the 
batteries, as described below

q Turn the instrument upside-down on the soft cloth, then open the battery com-

partment cover located on the instrument’s bottom panel.

w Insert the six new batteries as shown in the illustration, making sure that the 

positive and negative terminals are properly aligned.

e Replace the compartment cover, making sure that it locks firmly in place.
