MAINTENANCE
Cleaning the CD pickup lens
If the CD pickup lens is dirty, the sound may be
degraded.
Open the disc door and clean the lens.
Use a blower (available at a camera store, etc.) to blow
off dust on the lens.
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.
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.
