PREPARATION

CONNECTING POWER

You can power the CTR-108 from any of three power sources:

•Internal batteries

•Standard AC power (with the sup- plied power cord)

•Your vehicle’s cigarette-lighter socket (with an optional DC adapter)

Note: Connecting an AC power cord or a DC adapter disconnects the internal batteries.

Using Internal Batteries

You can power the CTR-108 from four C batteries (not supplied). For the best performance, we recommend alkaline batteries, such as RadioShack Cat. No. 23-551/651.

1.Press down on the battery com- partment cover and slide it off in the direction of the arrow.

2.Install the batteries as indicated by the polarity symbols (+ and –) marked inside the compartment.

Cautions:

•Use only fresh batteries of the required size and recom- mended type.

•Do not mix old and new batter- ies, different types of batteries (standard, alkaline, or re- chargeable), or rechargeable batteries of different capacities.

3.Replace the cover.

When the RECORD indicator be- comes dim, replace the batteries.

Cautions:

•Always dispose of old batteries promptly and properly.

•Never leave dead, old, or weak batteries in the CTR-108. They can leak chemicals and corrode or damage electronic circuits.

•If you do not plan to use the CTR- 108 for a week or more, or if you plan to use an adapter only, remove the batteries to protect the CTR-108 from possible battery leakage.
