Automatic Level Control (ALC) Circuit — ensures quality recording by automatically setting the proper recording level.

Record/Battery Indicator — flikers during recording and lights steadily when the batteries need replacing.

Built-inCondenser Microphone— gives you high-sensitivity for recording conferences or lectures.

Supplied Earphone — let you listen in privacy.

Auxiliary Input Jack — lets you connect a radio, tape deck, or CD player so you can record from these external audio sources.

External Microphone Jack — lets you connect an external microphone so you can record an individual but exclude the surrounding noise

Remote Control Jack — lets you connect an external microphone with an on/off switch so you can control the CTR-94 from your microphone.

Erasing Plug — plugs into the external microphone jack so you can erase a cassette tape by recording silence.

Retractable Handle — lets you easily carry the CTR-94.

Three Power Sources — let you power the CTR-94 from four C batteries (not supplied), standard AC power (with an optional AC adapter), or vehicle DC power (with an optional DC adapter).

PREPARATION

CONNECTING POWER

You can power your CTR-94from any of these power sources:

Internal batteries

Standard AC power (with an optional AC adapter)

Vehicle battery power (with an optional DC auto adapter)

Note: Connecting an adapter disconnects the internal batteries.

Cautions:

Always dispose of old batteries promptly and properly.

Never leave dead, old, or weak batteries in the CTR-94.Batteries can leak chemicals and corrode or damage electronic circuits.

If you do not plan to use batteries in the CTR-94for a month or more, remove the batteries to protect the CTR94 from possible battery leakage.

Using Internal Batteries

You can power your CTR-94from four C batteries (not supplied). For the best performance, we recommend alkaline batteries, such as Cat. No.23-551.

1.Press down on the battery compartment cover’s grooves and slide it off in the direction of the arrow.

3.Install the batteries as indicated by the polarity symbols (+ and –)marked inside the battery compartment.

Cautions:

Use only fresh batteries of the required size and type.

Never mix fresh and old batteries, or different battery types.

4.Replace the cover.

2.Remove the old batteries (if necessary).

Checking the Battery

Condition

To check the battery’s condition, press PLAY,REWIND, orFAST-F.If the RECORD/BATTERY indicator lights steadily, the batteries need replacing.

(illus)

Using AC Power

You can also power the CTR-94from standard AC power using an AC adapter, such as Radio Shack Cat. No.273-1662(not supplied).

Cautions:

The recommended adapter supplies 6 volts and delivers at least 300 milliamps. Its center tip is set to negative, and its plug correctly fits the CTR-94’sDC 6V jack. Using an adapter that does not meet these specifications could seriously damage theCTR-94or the adapter.

Always plug the adapter into the CTR-94before you plug it into the AC outlet, and always unplug the adapter from the AC outlet before you unplug it from theCTR-94.

Note: The recorder automatically disconnects internal batteries when you connect an AC adapter.

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

(illus)

2.Insert the adapter’s green-tippedbarrel plug into the adapter’s cord so it readsTIP-NEG.

(illus)

3.Plug the adapter’s barrel plug into the DC 6V jack on the left side of theCTR-94.

14-1107.fmPage 6 Thursday, July 1, 1999 11:15 AM

Using Vehicle Battery Power

You can also power the CTR-94from your vehicle’s battery using an auto DC adapter (such as Radio Shack Cat. No.14-844,not supplied) that connects to your vehicle’s cigarettelighter socket.

Cautions:

The recommended DC adapter supplies 6 volts and delivers at least 300 milliamps. Its center tip is set to negative, and its plug correctly fits the recorder’s DC 6V jack. Using an adapter that does not meet these specifications could seriously 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 thecigarette-lightersocket before you unplug it from the recorder.

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

2.Insert the DC adapter’s blacktipped barrel plug into the adapter’s cord so it reads TIPNEG.

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

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 is illegal in some areas.

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

OPERATION

LOADING A CASSETTE

PLAYING A TAPE

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

Warning: To protect your hearing, setVOLUME to its lowest setting before you begin playing a cassette tape.

(illus)

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

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

RECORDING

Notes:

Before you load a cassette tape for recording, be sure the cassette’s erase-protectiontabs are in place (see “Preventing Accidental Erasure”).

The CTR-94’sAutomatic Level Control (ALC) circuit automatically adjusts the recording level.VOLUME has no effect on recording.

Using the Built-In

Microphone

The built-incondenser microphone is ahigh-sensitivitymicrophone that easily picks up sounds, near or far. This is handy for recording conferences or lectures.

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

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

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

Using an External

Microphone

You can connect an external microphone with a 1/8-inchplug to the recorder. This is handy for when you want to record only an individual’s voice and exclude all other sounds in the surrounding area. Your local Radio Shack store carries a wide variety of external microphones.

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

Recording from an External Audio Source

You can record directly from an external audio source, such as a radio, tape deck, or CD player, using a suitable patch cord (not supplied) with a 1/8-inchplug.

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 setting.

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

2.If you connected an external microphone, disconnect it.

3.Connect your external audio source to the AUX jack, using an optional patch cord with a1/8- inch plug at one end and the appropriate plug at the other end that matches your audio source’s output jack.
