Radio Shack CTR-109 Owner's manual - Preparation

PREPARATION

CONNECTING POWER

You can power the CTR-109 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 the power cord or a

DC adapter disconnects the internal

batteries.

Using Internal Batteries

You can power the CTR-109 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 on the

cover.

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 becomes

dim, replace the batteries.

Cautions:

• Always dispose of old batteries

promptly and properly.

• Never leave dead, old, or weak

batteries in the CTR-109. They

can leak chemicals and corrode or

damage electronic circuits.

• If you do not plan to use the CTR-

109 for a week or more, or if you

plan to use an adapter only,

remove the batteries to protect the

CTR-109 from possible battery

leakage.
