FEATURES

Your Optimus CTR-106 Voice-Activated Cassette Tape

Recorder gives you a convenient and reliable way to record live audio. You can manually start recording or set the CTR-106 to automatically start recording when the recorder picks up sound.

Because the CTR-106 does not record long periods of silence, 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 briefcase or purse, so you can take it almost anywhere — meetings, lectures, and so on.

The cassette recorder includes these special features:

Voice-Activated Circuit — automatically starts recording when the recorder picks up sound and stops recording within 5 seconds after the sound falls below a set level.

Built-In Condenser Microphone — helps provide quality recordings.

Digital Tape Counter — helps you quickly return to a specific section on the tape.

14-1111.fm Page 3 Thursday, July 1, 1999 12:55 PM

Automatic Level Control (ALC) Circuit — automatically adjusts to the proper recording level.

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.

Three-Way Power — lets you operate your cassette recorder using internal batteries, an AC outlet (using an optional adapter), or your vehicle’s cigarette-lighter socket

(using an optional adapter).

Earphone — lets you listen without disturbing others.

You can also use the earphone to monitor a recording and check the microphone’s sensitivity.

Built-In Speaker — lets you listen to your recorder without an earphone.

PREPARATION

POWERING THE RECORDER

For portable use, you can power the recorder from internal batteries. 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. For the best results, we recommend alkaline batteries, such as RadioShack

Cat. No. 23-552. Or, you can use rechargeable nickelcadmium 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.

5

14-1111.fm Page 6 Thursday, July 1, 1999 12:55 PM

Follow these steps to install batteries.

Illust.

1. Slide the battery compartment cover in the direction shown by the arrow on the cover.

2. Install two AA batteries as indicated by the polarity symbols (+ and –) marked on the back of the recorder.

3. Replace the cover.

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 properly.

6

14-1111.fm Page 7 Thursday, July 1, 1999 12:55 PM

Important: Your recorder is capable of using rechargeable nickel-cadmium batteries. At the end of the batteries’ useful life, 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, recycling collection centers, and mailback 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 3 volts and delivers at least 300 milliamps. Its center tip must be set to negative, and it must have a plug that properly fits the CTR-106’s

DC 3V

jack. The recommended adapter meets these specifications. Using an adapter that does not meet these specifications could damage the CTR-106 or the adapter.

• Connecting an AC adapter automatically disconnects internal batteries.

7

8

14-1111.fm Page 8 Thursday, July 1, 1999 12:55 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.

Illust.

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 plug into the recorder’s

DC 3V

jack.

4. Plug the adapter into a standard AC outlet.

14-1111.fm Page 9 Thursday, July 1, 1999 12:55 PM

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. 270-1560.

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 it must have a plug that properly fits the CTR-106’s

DC 3V

jack. The recommended adapter meets these specifications. Using an adapter that does not meet these specifications could damage the CTR-106 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.

9

14-1111.fm Page 10 Thursday, July 1, 1999 12:55 PM

Follow these steps to power the recorder from your vehicle’s cigarette-lighter socket.

Illust.

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 DC adapter’s cord with the tip set to negative (–).

3. Insert the plug into the recorder’s

DC 3V

jack.

4. Plug 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.

EAR

jack.

Illust.

Note: Connecting the earphone disconnects the recorder’s built-in speaker.

11

14-1111.fm Page 12 Thursday, July 1, 1999 12:55 PM

Listening Safely

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

• Do not listen at extremely high volume levels.

Extended high-volume listening can lead to permanent hearing loss.

• Set the volume to its lowest level before you begin listening. After you put on the earphone, adjust the volume to a comfortable listening level.

• Do not increase the volume once you have established a comfortable listening level. 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 cause a traffic hazard and could be illegal in some areas.

Even though some earphones let you hear outside sounds when listening at normal volume levels, they still can present a traffic hazard.

RECORDING

Notes:

• We recommend you use normal bias (Type I) cassette tapes, such as RadioShack LN and XR tape.

• We recommend regular length (60- or 90-minute) cassette tapes. We do not recommend long-play cassette tapes, such as C-120s, because they are thin and can easily tangle.

• The ALC (automatic level control) circuit automatically sets the recording level.

VOLUME

TAPE TIPS

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, fast-forward 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.

Preventing Accidental Erasure

Cassette tapes have two eraseprotection 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.

18

Illust.

14-1111.fm Page 19 Thursday, July 1, 1999 12:55 PM

If you later decide to record on a tape side after you have removed the erase-protection 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.

Illust.

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

Erasing a Cassette Tape

To record over a cassette tape, simply record as usual.

The cassette deck records over the previous recording.

You can quickly erase both sides of a cassette tape using a bulk tape eraser, such as Cat. No. 44-232.

MAINTENANCE

Your CTR-106 Voice-Activated Cassette Tape Recorder is an example of superior design and craftsmanship. The following suggestions will help you care for your recorder so you can enjoy it for years.

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

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

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

Handle the recorder gently and carefully.

Dropping it can damage circuit boards and cases and can cause the recorder to work improperly.

20

14-1111.fm Page 21 Thursday, July 1, 1999 12:55 PM

Use only fresh batteries of the required size and type. Batteries can leak chemicals that damage your recorder’s electronic parts.

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

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

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 greatly reduce the performance of the cassette player. To prevent noise and poor high-frequency response, clean the cassette player’s tape-handling parts after about 20 hours of use. Your local RadioShack store sells cassette deck head-cleaning kits.

21

14-1111.fm Page 22 Thursday, July 1, 1999 12:55 PM

1. Disconnect all power sources.

2. Open the cassette compartment door.

3. Hold down the erase protection tab sensor, then

RECORD

to expose the tape-handling parts.

4. Use a cotton swab dipped in denatured alcohol or tape head-cleaning solution to clean the record/play head, pinch roller, capstan, erase head, and tape guides.

Illust.

5. When you finish cleaning, press

STOP

and close the compartment. Then reconnect power.
