Measuring instrument
- EVM (Electronic Voltmeter)
- Digital frequency counter
Test tape
- Headazimuth adjustment (8 kHz, -20 dB); QZZCFM
- Tape speed adjustment (3 kHz, -10 dB); QZZCWAT
- Playback gain adjustment (315 Hz, 0 dB); QZZCFM

9.1.1. Head Azimuth Adjustment
Note :
If you wish to readjust the head azimuth, be sure to adjust with adhering the casette tape closely
to the mechanism by pushing the center of cassette tape with your finger. (Shown in Fig. 1)
1. Connect the measuring instrument as shown in Fig. 2.
