7.2.2.3.3. AUDIO CONTROL HEAD HEIGHT ADJUSTMENT
The height of the Audio Control Head replacement part is preset at the factory.

Purpose:

To be sure the tape runs properly along the Control Head.

Symptom of Misadjustment:

If the control signal is not properly picked up, Servo Operation cannot
be achieved. A Blue screen will be seen in Playback.

This confirmation is required when the Audio Control Head is replaced.

1. Play back a T120 cassette tape and check that the lower edge of the

tape runs approximately 0.25 mm above the lower edge of the Audio
Control Head.

2. If necessary, adjust Black Screws (A) and (B) clockwise to lower the

tape or counterclockwise to raise.

Fig. M6

7.2.2.3.4. AUDIO CONTROL HEAD AZIMUTH ADJUSTMENT
