Maintenance
Cassette deck head care
To ensure good sound quality for recording and playback, be sure to
clean the heads approximately after every
1 0 hours of use.
1 ) Turn off the povirer of the system.
2) Press the stop/eject button to open the cassette holder.
3) Clean the heads, pinch roller, and the capstan shaft with a cotton
swab (or with a soft, lint-free cloth) slightly moistened wrtti isopro­
pyl alcohol. Do not use any solution other than alcohol for head
cleaning.
Cassette deck head demagnetization
In order to maintain good sound quality during recording and play­
back, we recommend that you demagnetize the head assembly if
there is still distortion or poor sound quality after you have cleaned
the heads.
If the head assembly becomes magnetized, it could create noise in
your recordings, cause a loss of high-frequency response, or cause
the erasure of valuable recordings. There are several types of head
demagnetizers that you can purchase at local electronics supply
stores.
Follow the instructions that are supplied with the derhagnetizer.
Do not touch the head assembly with any type of metal object or tool
such as a magnetic screwdriver.
Maintenance of external surfaces
Use a soft, dry cloth to clean the cabinet and controls.
If the surfaces are extremely dirty, use a soft cloth, dipped in a
soap-and-water solution or a weak detergent solution. Wring the cioth
well before wiping the surfaces. Then wipe once again with a soft, dry
cloth.
Never use alcohol, paint thinner, benzine, or a chemically treated
cloth to clean the cabinet or controls. Such chemicals may damage
the finish of your system.
