MAINTENANCE
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.
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.
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.
