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.

Using AC Power

To power the CTR-109 from standard

AC power, plug the supplied power

cord into the AC IN jack on the side of

the CTR-109. Then plug the other end

into a standard AC outlet.

Cautions:

• Always plug the power cord into

the AC IN jack before you plug it

into the AC outlet, and always

unplug the power cord from the

AC outlet before you unplug it

from the AC IN jack.

• The power cord has a polarized

plug that is designed to fit into the

recorder’s jack only one way. If the

plug does not easily fit into the

jack, do not force it. Simply turn it

over and try again.

Using Vehicle Battery Power

You can power the CTR-109 from your

vehicle’s cigarette-lighter socket using

a DC adapter, such as Cat. No. 273-

1802 (not supplied).

Cautions:

• You must use a DC adapter that

supplies 6 volts and delivers at

least 300 milliamps. Its center tip

must be set to negative, and its

plug ,ust correctly fit the CTR-

109’s DC IN 6V jack. The recom-

mended adapter meets these

specifications. Using an adapter

that does not could damage the

CTR-109 or the adapter.

• Always plug the adapter into the

CTR-109 before you plug it into

the cigarette-lighter socket, and

always unplug the adapter from

the cigarette-lighter socket before

you unplug it from the CTR-109.

Follow these steps to use vehicle bat-

tery power.

1. Set the DC adapter’s voltage

switch to 6V.

2. Insert the adapter’s barrel plug

into the CTR-109’s DC IN 6V jack.

3. Insert the adapter’s larger plug

into the vehicle’s cigarette-lighter

socket.

USING AN EARPHONE

For private listening, insert the sup-

plied earphone’s 1/8-inch plug into the

EAR jack.

Note: Connecting the earphone auto-

matically disconnects the built-in

speaker.

Listening Safely

To protect your hearing, follow these

guidelines when you use the ear-

phone.

• Set the volume to the lowest set-

ting before you begin listening.

After you begin listening, adjust

the volume to a comfortable level.

• Do not listen at extremely high vol-

ume levels. Extended high volume

listening can lead to permanent

hearing loss.

• Once you set the volume, do not

increase it. Over time, your ears

adapt to the volume level, so a vol-

ume level that does not cause dis-

comfort might still damage your

hearing.

Traffic Safety

Do not wear an earphone while operat-

ing a motor vehicle or riding a bicycle.

This can create a traffic hazard and

can be illegal in some areas.

Even though some earphones let you

hear some outside sounds when lis-

tening at normal volume levels, they

still can present a traffic hazard.

Using an External

Microphone

You can connect an external micro-

phone (not supplied) with a 1/8-inch

plug to the CTR-109. Your local

built-in microphone.

Follow these steps to record using an

external microphone.

1. Load a blank cassette tape, or one

you want to record over, into the

cassette compartment.

2. Insert the microphone’s plug into

the CTR-109’s MIC jack.

has a separate, smaller plug for

remote operation, insert that plug

into the REM jack. Then you can

use the microphone’s remote

switch to stop or start recording.

3. Press RECORD to begin record-

ing. Both PLAY and RECORD lock

Recording from a Connected

Audio Source

You can record directly from an exter-

nal audio source, such as a radio, tape

deck, or CD player. To make the con-

nection, you need a suitable mono

patch cord with a 1/8-inch plug (avail-

able at your local RadioShack store).

Note: Before you connect an external

audio source to the recorder, be sure

the source’s and the recorder’s volume

controls are set to their minimum set-

tings.

Follow these steps to record from an

external audio source.

Note: If you connected an external mi-

crophone, disconnect it.

you want to record over, into the

cassette compartment.
