Cleaning the heads, capstan and pinch roller

Cleaning is important!

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 satisfactorily.

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

Head (recording/playback)

Pinch roller

Erasure head

Capstan

Open the cassette holder. Clean the heads, capstan and pinch roller.

For effective cleaning, use a cleaning kit available at an audio store.

After cleaning, make sure that the cleaning fluid has dried completely before loading a cassette.

Cautions:

Keep magnets and metallic objects away from the 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 an audio store. When demagnetizing the head, the unit should be turned off.

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

Do not use anything other than alcohol for cleaning. Thinner and benzine will damage the rubber pinch roller.

Cleaning the CD pickup lens

If the CD pickup lens is dirty, the sound may be degraded.
