1. Tape Speed Adjustment
Settings : • Test tape : TTA–100(TAPE CENTER)

• Test point : PHONES JACK (J1)

• Adjustment location : SFR1

Method : Play back the test tape and adjust SFR1 so that

the frequency is 3000Hz±10Hz.

2. Head Azimuth Adjustment
Settings : • Test tape : TTA–300

• Test point : PHONES JACK (J1)

• Adjustment location : Head azimuth
adjustment screw

Method : Play back the test tape and adjust the screw

so that the output becomes maximum and
same phase
