PREPARATION
CONNECTING POWER
You can power the CTR-107 from any of three power
sources:
• Internal batteries
• Standard AC power (with an optional AC
adapter)
• Your vehicle’s cigarette-lighter socket (with an
optional DC adapter)
Note:
Connecting an adapter disconnects internal
batteries.
Using Internal Batteries
You can power the CTR-107 from four AA batteries
(not supplied). For the best performance, we recom-
mend alkaline batteries, such as RadioShack Cat.
No. 23-557.
You can also use rechargeable nickel-cadmium bat-
teries (Cat. No. 23-125) with a battery charger (Cat.
No. 23-133).
