Important!

Improper handling of batteries can cause them to burst and leak, which creates the

danger of personal injury or damage due to contact with battery acid. Be sure to note the

following important precautions.

•Always make sure that the positive (+) and negative (–) poles are facing correctly as

indicated inside the battery compartment.

•To avoid damage caused by leaking batteries, be sure to remove batteries from the

keyboard whenever you leave it unattended for long periods (such as when leaving

on a trip).

•Never mix batteries of different types.

•Never mix old batteries with new ones.

•Never discard batteries by incinerating them, do not allow their poles to be shorted

(connected to each other), never take batteries apart, and do not expose batteries to

direct heat.

•Replace batteries as soon as possible after any sign they are getting weak.

•Never attempt to recharge batteries.

■ Using the AC Adaptor

Make sure that you use only the AC adaptor specified for this keyboard.

Specified AC Adaptor: AD-5

Also note the following important warnings and precautions when using the AC

adaptor.

Warning!

•Take care to avoid any damage to or breakage of the power cord. Never place any

heavy objects on the power cord or expose it to direct heat. Doing so creates the

danger of power cord damage, fire, and electrical shock.
