í Head cleaning
After long usage, tape coating or dust may adhere to the heads,
causing deterioration of sound. Therefore, the parts depicted in
the illustration should be cleaned reguraly. Use a cotton swab
moistened with a tape head cleaning solution (such as alcohol).
Note:
1. Some cleaning cassettes on the market have strong abrasive
effects and may scratch the heads. Always use cotton swabs
instead of cleaning cassettes.
2. Since the use of metal tape is apt to collect more dust on the
heads, the heads should be cleaned more often to enjoy the
best possible sound.
í Cleaning the Pinch Rollers and Capstans
If the pinch roller or capstans accumulate dust, tape transport may
become unstable, as a result from slippage, during recording or
playback. The tape can also be damaged if it gets entangled in
the capstan.
Clean these parts with a cotton swab or a soft cloth moistened with
a tape head cleaning solution (such as alcohol).
í Demagnetizing the Heads
The heads may become magnetized after long usage or if
storongly magnetized objects are brought near them. The result is
a generation of noise, loss of the high frequency range, and in
extreme cases erasure of trable components on pre-recorded
tapes in combination with added noise.
Thus, the heads should be demagnetized at regular intervals.
(Head demagnetizers are sparately available from your dealer.)
í How to Demagnetize the Tape Heads
1. Turn off the power.
2. Turn on the demagnetizer while it is at least 30 cm away from
the heads. Bring the demagnetizer near the heads and slowly
move it in small circles four or five times in front of each head,
making sure you do not touch them.
3. Slowly move the demagnetizer away and turn it off when it is at
least 30 cm away from the heads.
4. For more details, please read the User Guide provided with the
demagnetizer (optional).
