FEATURES

Your Optimus CTR–113 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 opera-

tion while recording.

Because the CTR-113 does not record long periods of si-

lence, you not only save tape space and battery power,

you also save time when you try to find a certain section

on the tape. Your recorder is small enough to fit in a brief-

case 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.

ital Tape Counter — helps you quickly return to a

specific section on the tape.

One-Touch Recordin

— lets you press one button to

start recording.

used by Tandy Corporation.

14-1119.fm Page 2 Friday, July 2, 1999 3:28 PM

Cue/Review — lets you easily locate a certain section on

the tape.

Voice-Activated Circuit — automatically starts record-

ing when the recorder picks up sound and stops record-

ing within 5 seconds after the sound falls below a preset

level.

Built-In Microphone — lets you make quality recordings

without having to use an external microphone.

Wrist Strap — makes the recorder convenient to carry

and use.

Earphone — lets you listen without disturbing others.

Three-Way Power — lets you operate your cassette re-

corder using internal batteries, AC power (using an op-

tional adapter), or your vehicle’s cigarette-lighter socket

(using an optional adapter).

Built-In Speaker — lets you listen to your recorder with-

out an earphone.

Automatic Level Control (ALC) Circuit — automatically

adjusts to the proper recording level.

PREPARATION

POWERING THE RECORDER

For portable use, you can power the recorder from inter-

nal 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 recommend alkaline batteries, such

as RadioShack Cat. No. 23-552. Or, you can use re-

chargeable 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.

14-1119.fm Page 5 Friday, July 2, 1999 3:28 PM

Follow these steps to install batteries.

1. Slide the battery compartment cover in the direction

shown by the arrow on the cover.

Caution: The battery compartment cover is hinged.

Do not try to remove it.

2. Install two AA batteries as indicated by the polarity

symbols (+ and –) marked on the back of the

recorder.

3. Replace the cover.

When the recorder stops operating properly or the battery

light is low, replace the batteries.

Cautions:

• If you do not plan to use the recorder for a week or

more, or you plan to use only another power source,

remove the batteries.

• Always dispose of old batteries promptly and prop-

erly.

of batt. compartment cover

and installation of batteries.

14-1119.fm Page 6 Friday, July 2, 1999 3:28 PM

Important: Your recorder is capable of using recharge-

able nickel-cadmium batteries. At the end of the batteries’

lives, they must be recycled or disposed of properly. Con-

tact your local, county, or state hazardous waste man-

agement 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.

Using AC Power

To power the recorder from an AC outlet, you need an

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

Cautions:

• You must use an adapter that supplies at least 3 volts

and delivers at least 300 mA. Its center tip must be

set to negative, and its barrel plug must fit the CTR-

113’s DC 3V jack. The recommended adapter meets

these specifications. Using an adapter that does not

meet these specifications could damage the CTR-

113 or the adapter.

• Connecting an AC adapter automatically disconnects

internal batteries.

14-1119.fm Page 7 Friday, July 2, 1999 3:28 PM

• Always plug the adapter into the recorder before you

plug it into the AC outlet. Always unplug the adapter

from the AC outlet before you unplug it from the

recorder.

1. Set the adapter’s voltage switch to 3V.

2. Attach the 3.4 mm outer diameter/1.3 mm inner

diameter barrel plug to the AC adapter’s cord with the

tip set to negative (–).

3. Insert the barrel plug into the recorder’s DC 3V jack.

4. Plug the adapter into a standard AC outlet.

Using DC Power

To power the recorder from your vehicle’s cigarette-lighter

socket, you need a DC adapter (not supplied), such as

Cat. No. 273-1810 or Cat. No. 270-1560.

14-1119.fm Page 8 Friday, July 2, 1999 3:28 PM

Cautions:

• You must use an adapter that supplies 3 volts and

delivers at least 300 milliamps. Its center tip must be

set to negative, and its barrel plug must fit the CTR-

113’s DC 3V jack. The recommended adapter meets

these specifications. Using an adapter that does not

meet these specifications could damage the CTR-

113 or the adapter.

• Connecting a DC adapter automatically disconnects

internal batteries.

• Always plug the adapter into the recorder before you

plug it into the cigarette-lighter socket. Always unplug

the adapter from the cigarette-lighter socket before

you unplug it from the recorder.

Follow these steps to power the recorder from your vehi-

cle’s cigarette-lighter socket.

1. Set the adapter’s voltage switch to 3V.

14-1119.fm Page 9 Friday, July 2, 1999 3:28 PM

2. Attach the 3.4 mm outer diameter/1.3 mm inner

diameter barrel plug to the DC adapter’s cord with

the tip set to negative (–).

3. Insert the barrel plug into the recorder’s DC 3V jack.

4. Plug the other end of the adapter into the vehicle’s

cigarette-lighter socket.

Note: If the recorder does not operate properly when

powered from your vehicle’s battery, unplug the adapter

from the cigarette-lighter socket and clean the socket to

remove any ashes or other debris.

USING THE EARPHONE

You can use the supplied earphone for private listening.

Insert the earphone’s 1/8-inch (3.5-mm) plug into the EAR

jack.

Note: Connecting the earphone disconnects the record-

er’s built-in speaker.
