To connect a MIDI device to your keyboard, see “Making the MIDI Connections” on Page 12.

CONNECTING POWER

You can power your keyboard in any of these ways:

internal batteries

standard AC power using an optional AC adapter

a vehicle’s cigarette-lighter socket using an optional DC adapter

Notes:

Connecting an AC or DC adapter auto- matically disconnects internal batteries.

Always disconnect the AC or DC adapter when you finish using the key- board.

Using Batteries

Your keyboard can use six C batteries (not supplied) for power. For the best perfor- mance and longest life, we recommend RadioShack alkaline batteries.

Cautions:

Use only fresh batteries of the required size and recommended type.

Do not mix old and new batteries, differ- ent types of batteries (standard, alka- line, or rechargeable), or rechargeable batteries of different capacities.

1. Slide POWER to OFF.

2.Press the tabs on the battery compart- ment cover on the bottom of the key- board and pull up the cover to remove it.

3.Place the batteries in the compartment as indicated by the polarity symbols (+ and –) marked inside the compartment.

4.Replace the cover.

When the keyboard stops operating properly, replace the batteries.

Warning: Dispose of old batteries promptly and properly. Do not burn or bury them.

Caution: If you do not plan to use the key- board with batteries for a week or more, re- move the batteries. Batteries can leak chemicals that can destroy electronic parts.

Using AC/DC Power

You can power the keyboard using an op- tional 9V, 300-mA AC or DC adapter and a size M Adaptaplug™ adapter (none sup- plied). All are available at your local RadioShack store.

Cautions:

You must use a Class 2 power

!source that supplies 9V DC and delivers at least 300 mA.

Its center tip must be set to positive and its plug must fit the keyboard's

jack. Using an adapter that does not meet these specifications could damage the keyboard or the adapter.

Always connect the AC or DC adapter to the keyboard before you connect it to AC power or vehicle battery power. When you finish, disconnect the adapter from AC power or vehicle battery power
