PREPARATION

CONNECTING POWER

You can power the CTR-109 from any
of three power sources:

• Internal batteries

• Standard AC power (with the sup­plied power cord)

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

: Connecting the power cord or a

Note

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 recomme nd alkaline
batteries, such as RadioShack Cat.
No. 23-551/651.

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 recom­mended type.

• Do not mix old and new batter-

ies, different types of batteries
(standard, alkaline, or re­chargeable), 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.

remove the batteries to protect the
CTR-109 from possible battery
leakage.
