7.2.2.3. A/C HEAD HEIGHT ADJUSTMENT
The height of the A/C 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 can not be achieved.
1. Connect the oscilloscope to Pin 25 (PB Control signal) on
the TP Adjustment P.C.B.
2. Play back the Alignment Tape (VFMW0001C)
3. Confirm that the Sub Control Signal is 500 mV±200 mV. If
not, slightly and equally adjust Screw A, Screw B, and
Screw C on the A/C Head Unit to achieve the sub control
signal level of 500 mV±200 mV.
(Sub Control Signal level will decrease when rotating
screws clockwise, and increase when rotating screws
counterclockwise.)
