NOTE:

•

Power will be automatically drawn from the AC adaptor if the optional AC adaptor is connected

while batteries are installed in the instrument.

It is recommended that you replace worn batteries as soon as possible. When battery voltage

drops, the display will dim and / or the sound will become distorted, when this occurs, replace

the batteries with a complete set of six new batteries of the same type.

NEVER mix old and new batteries, different types of batteries (alkaline, magnesium, etc.), different

brand batteries or batteries from the same brand but of different types. Misuse may cause the

instrument to become hot, result in fire, or battery leakage.

Also, to prevent damage due to battery leakage, remove all the batteries from the instrument

when it is not to be used for an extended period of time.

If batteries are installed in this instrument, and the instrument is unused for a long period. They

will loose their power.

CAUTION:

Using Headphones Or Connecting An Amplifier

An optional set of stereo headphones can be connected

to the PHONES/INPUT jack located on the rear panel.

When headphones are connected to the jack, the

internal speakers of the unit will switch off automatically

(Perfect for private practice or late night playing). If you

would prefer to use an external sound system, the

PHONE/INPUT jack can also be used to connect the

electronic keyboard set to a stereo system or mixing

console.

Turn off the power on all equipment before

making any connections.
