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)

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 compartment 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 recommended type.

• Do not mix old and new batteries, 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.

• 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.

14-1116.fm Page 6 Friday, January 8, 1999 10:30 AM

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.

CTR-109 CASSETTE RECORDER

AC/DC/BATTERY

O P T

S

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 recommended 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 battery power.

REM

TONE VOLUME

• Once you set the volume, do not increase it. Over time, your ears adapt to the volume level, so a volume level that does not cause discomfort might still damage your hearing.

Traffic Safety

Do not wear an earphone while operating 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 listening at normal volume levels, they still can present a traffic hazard.

Note: Connecting the earphone automatically disconnects the built-in speaker.

Listening Safely

To protect your hearing, follow these guidelines when you use the earphone.

• Set the volume to the lowest setting before you begin listening.

After you begin listening, adjust the volume to a comfortable level.

• Do not listen at extremely high volume levels. Extended high volume listening can lead to permanent hearing loss.

-inch plug (available 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 settings.

USING THE TAPE

COUNTER

You can use the tape counter to help you find specific locations on the tape.

To return to a selection, fast-forward or rewind the tape until the counter shows the noted reading.

TAPE TIPS

Recommended Tapes

Tape quality greatly affects the quality of the recording. We recommend extended-range or low noise Type 1 regular length (60- or 90-minute) normalbias cassette tapes. We do not recommend long-play cassette tapes such as

C-120s because they are thin and can easily tangle.

Erasing a Cassette Tape

To record over a cassette tape, simply record as usual. The cassette deck records over the previous recording.

11

14-1116.fm Page 12 Friday, January 8, 1999 10:30 AM

To erase the entire cassette tape, insert the supplied erasing plug into the

MIC

jack and press

RECORD

. (Be sure you have not connected anything to the

AUX

jack.)

DC IN 6V

AUX EAR REM MIC TONE VOLUME

If you later decide to record on a tape side after you have removed its eraseprotection tab, place a piece of strong plastic tape over that side’s erase-protection hole. Be sure you cover only the hole originally covered by the erase-protection tab.

A

If you need to erase an entire cassette, you might prefer using a bulk tape eraser, available at your local

RadioShack store.

Preventing Accidental

Erasure

Cassette tapes have two erase-protection tabs — one for each side. When a tab is in place, you can record on that side.

To protect a recording from being accidentally recorded over or erased, use a screwdriver to remove one or both of the cassette tape’s erase-protection tabs. This prevents

RECORD

from being pressed.

Side A Tab

A

Caution: Removing the erase-protection tabs does not prevent a bulk eraser from erasing a cassette tape.

Restoring Tape Tension and

Sound Quality

After you play a cassette tape several times, the tape might become tightly wound on the reels. This can cause playback sound quality to deteriorate.

To restore the sound quality, fastforward the tape from the beginning to the end of one side, then completely rewind it. Then loosen the tape reels by gently tapping each side of the cassette’s outer shell on a flat surface.

Caution: Be careful not to damage the cassette when tapping it. Do not touch the exposed tape or allow any sharp objects near the cassette.

MAINTENANCE

Your RadioShack CTR-109 AC

DC Portable Cassette Recorder is an example of superior design and craftsmanship. The following suggestions will help you care for your CTR-109 so you can enjoy it for years.

Keep the CTR-109 dry. If it gets wet, wipe it dry immediately. Liquids might contain minerals that can corrode the electronic circuits.

Handle the CTR-109 gently and carefully. Dropping it can damage circuit boards and cases and can cause the CTR-109 to work improperly.

Use and store the CTR-109 only in normal temperature environments. Temperature extremes can shorten the life of electronic devices and distort or melt plastic parts.

Keep the CTR-109 away from dust and dirt, which can cause premature wear of parts.

Wipe the CTR-109 with a damp cloth occasionally to keep it looking new. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the CTR-109.

Modifying or tampering with the CTR-109’s internal components can cause a malfunction and might invalidate your CTR-109’s warranty. If your CTR-109 is not performing as it should, take it to your local RadioShack store for assistance.

14-1116.fm Page 14 Friday, January 8, 1999 10:30 AM

CLEANING THE TAPE-

HANDLING PARTS

Dirt, dust, or particles of the tape’s coating can accumulate on the tape heads and other parts that the tape touches. This can cause noise and poor high-frequency response which can greatly reduce the cassette player’s performance.

To help keep the cassette player working at its best, clean the cassette player’s tape-handling parts after every 20 hours of use using a tape cleaning kit, such as Cat. No. 44-1115.

1. Remove the batteries and disconnect any other power source.

2. Open the cassette compartment cover.

3. Press the erase-protection tab sensor, then

RECORD

to expose the tape-handling parts.

4. Gently clean the capstan, pinch roller, tape guides, and record/ play head.

and close the compartment door. Then reconnect power.
