MAINTENANCE

Cleaning the cabinet

Wipe it with a soft, dry cloth. Never use benzene or thinner as these could damage the surface finish.

Cleaning the heads, capstan and pinch roller

When the tape is running, magnetic powder and dust naturally accumulate on the heads, capstan and pinch roller.

When they become too dirty:

• Sound quality deteriorates.

• The sound output level drops.

• The previous recording is not completely erased.

• Recording is not performed correctly.

To avoid these, clean the heads, capstan and pinch roller every 10 hours of use.

For effective cleaning, use a cleaning kit available at audio stores. Make sure that the cleaning fluid has dried completely before loading a cassette.

Cleaning the CD pickup lens

If the CD pickup lens is dirty, clean the lens to prevent sound deterioration.

Gently wipe off fingerprints, etc. on the lens using a cotton swab.

To blow off dust on the lens, use a blower available at camera shops, etc., as shown below.

Capstan

Pinch roller

Note

Do not use thinner or benzene, as these will damage the rubber pinch roller (use of alcohol is permitted).

Demagnetizing the recording/playback head

If the head becomes magnetized, noise will increase and the sound will deteriorate.

Demagnetize the recording/playback head every 20 to

30 hours of use with a head demagnetizer available at audio stores. When demagnetizing the head, turn off the unit to the standby mode by pressing the STANDBY/

ON button.

Caution

As the erasure head of the unit is of magnetic type, do not demagnetize it.
