ADJUSTMENT
<TAPE PLAYER SECTION>
1. Tape Speed (4.8cm/sec) Adjustment
Settings : • Test tape : TTA - 100 (TAPE CENTER)
• Test point : PHONES JACK (J101)
• Adjustment location : SFR 401
• Super bass : OFF
• Volume : MAX
Method : Play back the test tape and adjust SFR 401 so that the
frequency is 3010 Hz ±10 Hz (FWD) and FWD SPEED
±50 Hz (REV). Then confirm WOW is less than 0.52%.
