PREPARATION
POWERING YOUR 
KEYBOARD
You can power your Concertmate 410
with.
• Internal batteries (see “Using Bat-
teries”)
• Standard AC power using an
optional AC adapter (see “Using
AC Power” on Page 6)
• A vehicle’s cigarette lighter socket
using an optional DC adapter (see
“Using Vehicle Battery Power” on
Page 6)
Notes:
• Connecting an AC or DC adapter
automatically disconnects internal
batteries.
• Always disconnect the AC or DC
adapter when you finish using the
Concertmate 410.
Using Batteries
Your Concertmate 410 can use six C
batteries (not supplied) for power. We
recommend alkaline batteries, such as
RadioShack Cat. No. 23-551.
Caution: Only use fresh batteries of
the required size and type.
1. Press the tabs on the battery com-
partment cover, then pull up in the
direction of the arrows to remove
the cover.
2. Put the batteries in the compart-
ment as indicated by the polarity
symbols (+ and –) marked inside.
3. Replace the cover.
Notes:
• If you do not plan to power the
Concertmate 410 from batteries
for a week or more, or if you plan
to use only AC or vehicle battery
power, remove the batteries.
• If the Concertmate 410 sounds
weak or does not work properly,
replace all six batteries. Do not
mix old and new batteries.
Caution: Dispose of old batteries
promptly and properly.
