PREPARATION
CONNECTING POWER
For portable use, you can power your
Concertmate 690 using internal batter-
ies. Using optional adapters, you can
also power it from a standard AC outlet
or your vehicle’s cigarette lighter sock-
et.
Notes:
Connecting an AC or DC adapter
automatically disconnects internal
batteries.
Always disconnect an AC or DC
adapter when you finish using the
Concertmate 690.
Using Batteries
Your Concertmate 690 can use six AA
batteries for power. For the best per-
formance, we recommend alkaline
batteries, such as RadioShack Cat.
No. 23-552.
Cautions:
Use only fresh batteries of the re-
quired size and recommended
type.
Do not mix old and new batteries,
different types of batteries (stan-
dard, alkaline, or rechargeable),
or rechargeable batteries of differ-
ent capacities.

batteries.
