The marking this product has been classified as Class 1.

It means that there is no danger of hazardous radiation

outside the product.

Location: Bottom

Resetting the Microcomputer

The microcomputer may malfunction (unit can-

not be operated, or shows an erroneous dis-

play) if the power cord is unplugged while the

power is ON, or due to some other external

factor. If this happens, execute the following

procedure to reset the microcomputer and

return the unit to its normal operating condition.

Plug in the AC power cord to the wall outlet,

and within 5 seconds, press and hold down

the

button and press CD button.

Please note that resetting the microcomputer

will clear the contents of the memory and

return the unit to the state it was in when it

left the factory .

ADJUSTMENT

SERVICE ADJUSTMENT

Lubrication

The mechanical parts are factory coated with a thin coat of light grease and should not require further

lubrication. If a light grease is applied, be careful not to get any grease on the play/record head or erase

head, hubs, pulleys, tapes reels, drive belts, or switches. Use a good lubricant such as Silicon Lube G322L

or Lubricate.

Service Check

Before aligning the mechanism, wipe off any accumulated dirt with denatured alcohol. Wipe around parts

where the tape contacts and around all rotating parts. Drive belts are specially processed. Do not clean

them with alcohol.

Mechanical Torque

Use a cassette type torque gauge and check the tape mechanism.

Take-up torque 35 to 70 g-cm

Rewind torque 50 g-cm min.

Fast forward torque 50 g-cm min.

Pinch Wheel Pressure

No adjustment to the pinch roller spring is necessary. It should be sufficient to give at least 40 g-cm pull

force.

Tape Head Servicing

Each time the unit is serviced, the face of all heads should be thoroughly cleaned with denatured alcohol or

commercial head cleaning solution. The playback head should be demagnetized with a commercial

demagnetizer. Accumulation of tape oxide during normal operations can cause problems, including loss of

high frequencies and wow and flutter.

Erase Head

The erase head is properly aligned when the tape rides directly between the tape guide on the head without

crinkling the tape.

Play/Record and Playback Head Azimuth Adjustment

To adjust the play/record and playback head azimuth screw:

1. Connect two (2) VTVMs and a dual trace scope to the stereo headphone jack (as shown) with a 32

ohm dummy load. (See Figure 1.)

ADJUSTMENT

2. Insert a 10 kHz test tape (Teac MTT-1141V or Equivalent) into the tape mechanism and play it back.

3. While playing back the test tape, slowly turn the azimuth adjusting screw until the amplitude of both

channel output waveforms is maximum and in phase. Note: Reiteration adjusting Right, lift the screw,

until the amplitude of both channel output waveform is maximum. (See Figure 2.)

4. Secure the azimuth screw in place with glue or paint after making the adjustment.

Tape Speed Adjustment

1. Set the function switch to TAPE.

2. Connect a frequency counter with a 32 ohm dummy load to the stereo headphone jack. (See Figure 3.)

3. Insert and play back a 3 kHz test tape (Teac MTT-111 or Equivalent) into the tape mechanism.

4. Insert an insulated alignment tool and adjust the tape speed potentiometer (MOTOR) until the

frequency counter indicates 2940 Hz to 3090 Hz.

Bias Oscillator Frequency and Level Adjustment

1. Set the function switch to TAPE and the record and play tape mechanism to RECORD.

2. Connect a VTVM and frequency counter to test point R/P HEAD.

3. Adjust bias oscillator coil L203 until the frequency counter indicates 67 kHz ±0.5 kHz.
