PREPARATION

POWERING THE CTR-116

You can operate your CTR-116 from any of these power sourc-
es:
four AA batteries (not supplied)
standard AC power (using an optional AC adapter)
vehicle battery power (using an optional DC adapter)
Note: Using an adapter automatically disconnects the internal
batteries.

Installing Batteries

You can power the CTR-116 with four AA batteries. For the
longest life, we recommend alkaline batteries. Or, you can use
rechargeable nickel-cadmium batteries (RadioShack Cat. No.
23-325) and charge them with a battery charger, such as Cat.
No. 23-242.
Cautions:
Use only fresh batteries of the required size and recom-
mended type.
Do not mix old and new batteries, different types of batter-
ies (standard, alkaline, or rechargeable), or rechargeable
batteries of different capacities.
