PREPARATION

Note: To connect a MIDI device to your
keyboard, see "Making the MIDI Connec-
tions" on Page 25.

CONNECTING POWER

You can power your keyboard in any of
these ways:
• internal batteries
• standard AC power
optional AC adapter
• a vehicle's cigarette-lighter socket
using an optional DC adapter
Notes:
• Connecting an AC or DC adapter
automatically disconnects any inter-
nal batteries.
• Always disconnect the AC or DC
adapter when you finish using the
keyboard.

Using Batteries

Your keyboard can use six D batteries
(not supplied) for power. For the best
performance, we recommend alkaline
batteries, such as RadioShack Cat. No.
23-550.
Cautions:
• Use only fresh batteries of the
required size and recommended
type.
• Do not mix old and new batteries,
different types of batteries (stan-
dard, alkaline, or rechargeable), or
6
rechargeable batteries of different
capacities.
1. Set
2. While pressing both tabs on the bat-
tery compartment cover on the bot-
using an
tom of the keyboard, pull the cover
up to remove it.
3. Put six D batteries into the compart-
ment as indicated by the polarity
symbols (+ and –) marked below the
compartment.
4. Replace the cover.
When the keyboard stops operating
properly, replace all six batteries.
Cautions:
• If you do not plan to use the key-
board for a week or more, or if you
plan to use only an AC or DC
adapter, remove the batteries. Bat-
teries can leak chemicals that can
destroy electronic parts.
• Dispose of old batteries promptly
and properly. Do not burn or bury
them.
