in Fig. 4-6:
. Attach head position alignment jigs A and B, then set the deck
to the play mode,
Fit jig B on the tape guide of the record/playback head as
shown in Fig. 4-5, then align the height with screw (A) as shown
in Fig. 4-6,
Fit jig B to the head as shawn in Fig. 4-5 to check its tilt and
align it using screws (B) and (C) shown in Fig. 4-6, Then align
the height again with screw (A).
Repeat alignments in procedure 2 and 3 two or three times to
align height and tilt. (When adjusted to the standard height,
the head should be wnder the tape guide.)
. Fit jig B to the tape guide of the ieft pinch roller and align the
height with nut {E). (The standard height is above the tape
guide,)
. Play test tape MTT-902, and adjust nut (E) so that the lower
edge of the tape guide of the record/playback head is in.contact
with the tape edge, but the tape is not curted.
. Adjust the azimuth of the playhack head with screw (C) shown
in Fig. 4-6 according to item 5-3 (an page 15). If the screw is
rotated by half a turn or more, turn screws (A) and (B) by the
same amount then align again from item 6 to correct the height
of the tape guide of the record/playback head.
. Adjust the azimuth of the recard head with screw (0) shown
in Fig. 4-6 according to item 5-5, (Refer to page 18.)
