MAINTENANCE
CLEANING
THE
HEADS,
PINCH
ROLLERS,
AND CAPSTAN
The heads, capstan, and pinch roller of a cassette deck are parts easily
contaminated by dirt, dust, and oil during tape travel. Dirty heads in
* particular result in poor tape-to-head
contact, causing poor sound
quality, upsetting stereo balance, and causing fluctuations in tape
speed. Clean the heads regularly with special head-cleaning swabs, or
* a soft cloth dipped in cleaning fluid.
1. Open the head cleaning access port.
2. Set the POWER switch to ON.
3. Press the PLAY
switch. The head base will rise and the pinch
rollers will begin rotating.
4. Moisten a cleaning swab lightly with cleaning fluid, and gently
wipe the heads, pinch rollers, and capstans.
NOTE:
e
After cleaning, do not load a tape (for 2 to 3 minutes) until the
cleaning fluid has dried.

Set the stereo amplifier's volume control to the minimum posi-
tion when cleaning the heads.

DEMAGNETIZING THE HEADS
After using the cassette deck over a period of time, the heads will
become: magnetized.
The same effect is also caused by bringing a
screwdriver, magnet or other magnetized object too near the heads.
This causes
loss of high-frequency
sound
during
recording
and
playback, and is also a cause of interference noise. The heads should
be regularly demagnetized with a head demagnetizer (eraser). which
can be purchased at the dealers shops.
When demagnetizing the heads, be sure the cassette deck's POWER
switch is in the OFF position. For detailed instructions, consult the
operating manual for your head demagnetizer (eraser).
CLEANING THE FRONT PANEL SECTION
Wipe the front panel and the cassette holder when dusty or greasy
with a soft cloth containing a small amount of ordinary washing-up li-
quid. Then, wipe dry with a cloth. Never use volatile spirits like thin-
ners, benzine or alcohol because they will damage the panel's finish.
