Maintenance_
■ Head care
To assure good sound quality for recording and playback, be sure
to clean the heads after approximately every 10 hours of use.
1. Press the stop/cassette holder open button to open the cassette
holder.
2. Switch the power of this unit to standby mode.
3. Clean the heads, pinch roller and the capstan shaft of each deck
with a cotton swab (or with a soft, lint-free cloth) slightly mois¬
tened with alcohol.
Do not use any solution other than alcohol for head cleaning.
■ Head demagnetization
•In order to maintain good sound quality during recording and
playback, it is recommended that the heads should be demagne¬
tized if distortion or poor sound quality persist after cleaning the
heads.
• If the heads become magnetized, they could create noise in
recordings, loss of high-frequency response, or erasure of valu¬
able recordings. Several types of head demagnetizers are avail¬
able and may be purchased at local electronics supply stores.
Follow the instructions that are supplied with the device.
• Do not bring any type of metal objects or tools such as magnetic
screwdrivers in contact with the head assembly.
■ Maintenance of external surfaces
•To clean this unit, use a soft, dry cloth.
For very dirty surfaces, dip a soft cloth in a weak soap-and-water
solution and wring well. After cleaning, wipe with a soft, dry cloth.
• Never use alcohol, paint thinner, benzine, or a chemically treated
cloth to clean this unit.
Such chemicals may damage the system's finish.
