PRECAUTION

1. Clean the following parts with a denatured alcohol-moistened swab : record/playback/erase head pinch roller rubber belts capstan idlers 2. Demagnetize the record/playback head with a head demagnetizer. 3. Do not use a magnetized screwdriver for the adjustment. 4. After the adjustments, apply suitable locking compound to the parts adjusted. 5. The adjustments should be performed with the rated power supply voltage unless otherwise noted.
