PREPARATION
CONNECTING POWER
You can power your Concertmate 970
in any of these ways.
• 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 adapter
when you finish using the Con-
certmate 970.
Using Batteries
Your Concertmate 970 can use six AA
batteries (not supplied) for power. For
the best performance, we recommend
alkaline batteries, such as RadioShack
Cat. No. 23-557.
Cautions:
• Only use fresh batteries of the
required size and type.
• Be sure POWER/MODE is set to
OFF while you install batteries.
1. Press the tab on the battery com-
partment cover, then pull up to
remove the cover.
2. Put the batteries in the compart-
ment as indicated by the polarity
symbols (+ and –) marked beside
the compartment .
3. Replace the cover.
Notes:
• If you won’t be using the Concert-
mate 970 with batteries for a week
or more, or if you will be using
only AC or vehicle battery power,
remove the batteries.
• If the Concertmate 970 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.
