Preparation

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.

Preparation
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
DC 9V
