ˆ Preparation


You can power the recorder from any of three power sources:

Standard AC power (with the supplied power cord)

Internal batteries

Your vehicle’s cigarette-lightersocket (with an optional DC adapter)

Note: Connecting the power cord or a DC adapter disconnects the internal batteries.

Using AC Power

To power the recorder from standard AC power, plug the supplied power cord into the AC IN jack on the side of the recorder. Then plug the other end into a standard AC outlet.

Warning: The power cord has a polarized plug that is designed to fit into the recorder’s jack and a standard AC outlet only one way. If the plug does not easily fit into the jack and AC outlet, do not force either plug. Simply turn it over and try again.

Caution: Always plug the power cord into theAC 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.

Using Internal Batteries

You can power the recorder from four C batteries (not supplied). For the best performance and longest life, we recommend RadioShack alkaline batteries.


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.

Follow these steps to install batteries.

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 in the compartment as indicated by the polarity symbols (+ and –)marked inside.

3.Replace the cover.



















14-1128.fmPage 4 Thursday, April 6, 2000 3:24 PM

When the record/battery indicator becomes dim during recording or the recorder stops operating properly, replace the batteries.

Warning: Always dispose of old batteries promptly and properly. Do not burn or bury them.

Caution: If you do not plan to use the recorder with batteries for a month or more, remove the batteries. Batteries can leak chemicals that can destroy electronic parts.

Using Vehicle Battery Power

You can power the recorder from your vehicle’s cigarette-lightersocket using a 6V, 300 mA DC adapter and a size B Adaptaplug™ adapter (neither supplied, available at your local RadioShack store).


You must use a DC adapter that supplies 6 volts and delivers at least 300 milliamps. Its center tip must be set to positive, and its plug must correctly fit the recorder’s DC 6V jack. Using an adapter that does not meet these requirements could damage the recorder or the adapter.

Always plug the adapter into the recorder before you plug it into the cigarette-lightersocket, and always unplug the adapter from the ciga-rette-lightersocket before you unplug it from the recorder.

Follow these steps to use vehicle battery power.

1.Set the DC adapter’s voltage switch to 6V.

2.Insert the Adaptaplug adapter into the adapter’s cord so it reads + TIP.

3.Insert the Adaptaplug’s barrel plug into the DC 6V jack on the left side of the recorder.

4.Insert the adapter’s larger plug into the vehicle’s cigarette-lightersocket.


You can use an optional mono earphone with a 1/8-inch(3.5-mm)mini plug to listen to a tape privately. Insert the earphone’s1/8-inchplug into theEAR jack.

Note: Connecting the earphone automatically disconnects thebuilt-inspeaker.

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.

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.

ˆ Operation


1.Take up any slack in the tape by turning one of the cassette’s hubs with a pencil.

3.Load the cassette into the cassette guides in the door with its open edge out, the side you want to play facing up, and its full reel to the left.

4.Close the door.

Caution: If you do not remove the excess slack, the tape could become tangled in the record/playback mechanism.

2.Press STOP/EJECT to open the cassette compartment door.


1.Load the cassette tape.

2.Press PLAY. The cassette plays until it reaches the end of the side, then it automatically stops.


Press PAUSE to temporarily stop playback. PressPAUSE again to resume playback.

PLAY to resume playback.

If you hold down REWIND/REVIEWor FAST-F/CUEwhile the tape is playing, you can hear the tape as it moves at a faster speed. This makes it easy to locate a specific part of a recording. When you release REWIND/REVIEWor FAST- F/CUE, the tape plays at its normal speed.

3.Adjust TONEand VOLUME/VOX SENSto a comfortable listening level.

4.To stop playback before the tape automatically stops, press STOP/ EJECT.



Before you load a cassette tape for recording, be sure its erase-protec-tion tabs are in place (see “Preventing Accidental Erasure” on Page 8).

The recorder’s Automatic Level Control (ALC) circuit automatically adjusts the recording level. VOLUME/VOX SENS has no effect on recording.

4.Press RECORD to begin recording. BothPLAY andRECORD lock down.

Note: To temporarily stop recording, pressPAUSE. PressPAUSE again to resume recording.

5.The recorder automatically stops the tape when it reaches the end of the current side. To stop recording sooner, press STOP/EJECT.

Using an External Microphone

You can connect an external microphone (not supplied) with a 1/8-inchplug to the recorder. Your local RadioShack store sells a variety of microphones.

Note: Connecting an external microphone automatically disconnects thebuilt-inmicrophone.

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 recorder’s MIC jack.

Using the Built-InMicrophone

1.Load a blank cassette tape, or one you want to record over, into the cassette compartment.

2.Place the recorder 2 to 3 feet from the recording source.

1.Load a blank cassette tape, or one you want to record over, into the cassette compartment.

2.Connect the external source to the AUX jack using a patch cord with a1/8-inchplug.

VOX Recording

When you use VOX recording, the recorder automatically begins recording when it senses a voice or other sound, then automatically stops when the sound stops.

To start VOX recording, set VOX toON then adjustVOLUME/VOX SENS to set the sound level at which recording begins. RotatingVOLUME/VOX SENS to the left increases the VOX sensitivity. The higher the VOX sensitivity, the lower the sound level is needed to start VOX recording.

Recording from a Connected Audio Source

You can record directly from an external audio source, such as a radio, tape deck, or CD player. To make the connection, you need a suitable mono patch cord with a 1/8-inch(3.5-mm)plug (available at your local RadioShack store).

Note: Before you connect an external audio source to the recorder, be sure the source’s volume control is set to its minimum setting.

Follow these steps to record from an external audio source.

3.Start the external audio source and set its volume control to a normal listening level.

4.Press RECORD to begin recording. BothPLAY andRECORD lock down.

Note: To temporarily stop recording, pressPAUSE. To resume recording, pressPAUSE again.

5.The recorder automatically stops the tape when it reaches the end of the current side. To stop recording sooner, press STOP/EJECT. Then stop the audio source.

Note: During recording, the speaker is muted. If you want to monitor the recording, connect an earphone (not supplied) (see “Using an Earphone” on Page 4).



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



















14-1128.fmPage 8 Thursday, April 6, 2000 3:24 PM

At the beginning of a tape, press TAPE COUNTER to reset the tape counter to000. Then note the counter’s reading at the beginning of each selection.

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


Recommended Tapes

Tape quality greatly affects the quality of the recording. We recommend extendedrange or low noise Type 1 regular length (60or 90-minute)normal-biascassette tapes. We do not recommendlong-playcassette tapes such asC-120sbecause they are thin and can easily tangle.

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 edge of the cassette 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.

Erasing Tapes

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 RadioShack bulk tape eraser.

Note: If you use metal orhigh-biastype tape, the recorded sound might not be erased properly.

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 prevent accidental erasure of a tape recording, use a screwdriver to remove one or both of the cassette tape’s eraseprotection tabs. This prevents RECORD from being pressed.

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

Caution: Removing theerase-protectiontabs does not prevent a bulk eraser from erasing a cassette tape.

ˆ Care and Maintenance

Your RadioShack Portable Cassette 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, damage batteries, 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.

Use only fresh batteries of the required size and recommended 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 components can cause a malfunction and might invalidate its warranty. If your recorder is not performing as it should, take it to your local RadioShack store for assistance.
