■

Using an AC Adaptor

Use only the AC adaptor (JEITA Standard, with unified
polarity plug) that comes with this Digital Piano. Use of a
different type of AC adaptor can cause malfunction.

• Use the supplied power cord to connect the AC adaptor.

Bottom

IMPORTANT!

• Never connect the AC adaptor that comes with this

Digital Piano to any other device besides this Digital
Piano. Doing so creates the risk of malfunction.

• Make sure the Digital Piano is turned off before

plugging in or unplugging the AC adaptor.

• The AC adaptor will become warm to the touch after

very long use. This is normal and does not indicate
malfunction.

• Never try to use the supplied power cord with any

other device.

• Place the AC adaptor on the floor with its label

surface pointed downwards. The AC adaptor
becomes more prone to electromagnetic wave
generation if the label surface is in a different
position.
