1. Demagnetize the record/playback head with a head damagnetizer. 2. Do not use a magnetized screwdriver for the adjustments. 3. After the adjustments, apply suitable locking compound to the parts adjusted. 4. The adjustments should be performed with the rated power supply voltage unless otherwise noted. 5. The adjustments should be performed in the order given in this service manual. (As a general rule, playback circuit adjustment should be completed before performing recording circuit adjustment.) 6. The adjustments should be performed for both L-CH and R-CH. 7. Switches and controls should be set as follows unless otherwise specified.
