FEATURES

Your Optimus CTR–11 3 Voice-Activated Cassette Tape
Recorder gives you convenient recording technology.
You can have recording begin and end according to the
sound level in a room, which gives you hands-free opera­tion while recording.

Because the CTR-113 does not record long periods of si­lence, you not only save tape space and battery power,
you also save time whe n you try t o find a certain sec tion
on the tape. Your recorder is small enough to fit in a brief­case or purse, so you can take it almost anywhere.

The cassette recorder includes these special features:

Semi Auto Stop

— during playback and recording, stops
the recorder and releases the tape mechanism when the
tape reaches the end, to save battery power and protect
your cassette tape.

Di

ital Tape Counter

— helps you quickly return to a

specific section on the tape.

One-Touch Recordi n

lets you press one button to

—

start recording.

PREPARATION

POWERING THE RECORDER

For portable use, you can p ower the recorder from inter­nal batteries. Using adapters, you can also power it from
a standard AC outlet or your vehicle’s cigarette-lighter
socket.

Using Internal Battery Power

The recorder uses two AA batteries (not supplied). For
the best results, we reco mmend alkaline batteries, such
as RadioShack Cat. No. 23-552. Or, you can use re­chargeable nickel-cadmium batteries, such as Cat. No.
23-125, with a battery charger (Cat. No. 23-133).

Cautions:

• Use only fresh batteries of the recommended size

and type.

• Do not mix old and new batteries, different types of

batteries (standard, alkaline, or rechargeable), or
rechargeable batteries of different capacities.

Important:

Your recorder is capable of using re charge­able nickel-cadmium batteries. At the end of the batteries’
lives, they must be recycled or disposed of properly. Con­tact your local, county, or state hazardous waste man­agement authorities for information on recycling or
disposal programs in your area. Some options that might
be available are: municipal curbside collection, drop-off
boxes at retailers such as your local RadioShack store,
recycling collection centers, and mail-back programs.

AC adapter (not supplied), such as Cat. No. 273-1654.
