MAINTENANCE

Cleaning is important!

When the tape is running, magnetic powder and dust naturally accu- mulate on the heads, capstan and pinch roller. When they become too dirty...

●Sound quality deteriorates.

●The output sound level drops.

●Previously recorded tape is not completely erased.

●Recording is not performed satisfactorily.

Therefore, you should clean the heads, etc. after every 10 hours of use for optimal recording conditions.

Cleaning the heads, capstan and pinch roller

Open the cassette holder.

Clean the heads, pinch roller and capstan.

For effective cleaning, use a cleaning kit available from an audio store. After cleaning, be sure that the cleaning fluid has dried completely be- fore loading a cassette.

Erase head Combination record/play head

Cautions:

1.Keep magnets and metallic objects away from the head.

If the head becomes magnetized, noise will increase and the sound will deteriorate. Demagnetize the head every 20–30 hours of use with a head eraser (available from an audio store). (When demag-

netizing the head, the button should be set to STANDBY.)

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

Cleaning the lens

If the lens in the CD pickup is dirty, dropout, etc., could degrade sound. Open the CD holder and clean the lens as shown.

●Use a blower (available from a camera store) to blow dust off the lens.

●If there are fingerprints, etc. on the lens, gently wipe clean with a cotton swab.
