1. Head Azimuth Adjustment
Setting: • Test tape: TTS-930
• Tape speed: 2.4 cm
• Adjustment point: Head Azimuth Adjustment screw
Method: Playback the 5 kHz signal of the test tape (TTS-930)
and adjust screw so that the output becomes maximum.
2. Tape Speed Adjustment (2.4cm)
Setting: • T est tape: TTS-900
