Getting Ready to Play
Either an AC adaptor or batteries can be used to power this
Digital Keyboard. Normally, use of AC adaptor power is
recommended.
• The AC adaptor does not come with this Digital Keyboard.
Purchase it separately from your retailer. See page E-3 for
information about options.
Make sure that you use only the AC adaptor specified for this
Digital Keyboard. Use of a different type of AC adaptor can
cause malfunction.
• Be sure to turn off Digital Keyboard power before
connecting or disconnecting the AC adaptor.
• The AC adaptor will become warm to the touch after
very long use. This is normal and does not indicate
malfunction.
• To prevent breaking of the wire, take care to avoid
putting any type of load on the power cord.
• Never insert metal, pencils, or any other objects into
the product’s 9.5V DC terminal. Doing so creates the
risk of accident.
• Be sure to turn off power before loading batteries.
• It is up to you to prepare six commercially available
batteries. Do not use oxyride batteries or any other
nickel based batteries.
1.
Open the battery cover on the bottom of the
Digital Keyboard.

Load six batteries into the battery compartment.
• CTK-4200: AA-size batteries
• WK-220/WK-225: D-size batteries

Insert the tabs of the battery cover into the
holes on the side of the battery compartment,
and close the cover.
