1. Clean the following parts with a denatured-alcohol-moistened swab: record/playback/erase head pinch roller capstan rubber belt 2. Demagnetize the record/playback/erase head with a head demag netizer. 3. Do not use a magnetized screwdriver for the adjustments. 4. The adjustments should be performed with the rated power supply voltage (3 V) unless otherwise noted. Torque Measurement

Procedure: 1. Set [REC TIME] switch (S401) to NORMAL (4.8 cm/s) position, and playback the tape (WS-48A) . 2. Adjust RV602 so that frequency counter reading becomes 3,010 Hz. 3. Set [REC TIME] switch (S401) to DOUBLE (2.4 cm/s) position. 4.Playback the tape from the beginning for two minutes, then adjust RV601 so that frequency counter reading becomes 1,505 Hz.
