1) Playback the SW/OL standard tape. (WR5-2D)
2) Turn the tape guide No.3 and No.6 alternately until the wave-

form becomes flat. (Fig. 6-2-6)

Zenith adjustment screws for the TG3 and TG6 do not
need to be adjusted.

3) Turn the No.3 guide slowly in the clockwise direction until

the waveform amplitude at the entrance side begins to become
small. (Fig. 6-2-7 (A))
Confirm the rotation angle (A) of the No.3 guide.

4) Turn the No.3 guide slowly in the counterclockwise direction

until the waveform becomes flat. (Fig. 6-2-6)

5) Turn the No.3 guide slowly in the counterclockwise direction

until the waveform amplitude at the entrance side begins to
become small. (Fig. 6-2-7 (B))
Confirm the rotation angle (B) of the No.3 guide.

6) Turn the No.3 guide slowly in the clockwise direction and set

up in the angle (C) in the middle of the rotation angle (A) and
the rotation angle (B). (Fig. 6-2-5)

7) Turn the No.6 guide slowly in the clockwise direction until

the waveform amplitude at the exit side begins to become small.
(Fig. 6-2-8 (A))
Confirm the rotation angle (A) of the No.6 guide.

8) Turn the No.6 guide slowly in the counterclockwise direction

until the waveform becomes flat. (Fig. 6-2-6)

9) Turn the No.6 guide slowly in the counterclockwise direction

until the waveform amplitude at the exit side begins to be-
come small. (Fig. 6-2-8 (B))
Confirm the rotation angle (B) of the No.6 guide.

10) Turn the No.3 guide slowly in the clockwise direction and set

up in the angle (C) in the middle of the rotation angle (A) and
the rotation angle (B). (Fig. 6-2-5)

1) Playback a tape in REV mode.
2) Confirm that tape slack dose not occur in between the guide

No.6 (TG6) 1 and capstan 2. If the tape slack is found, turn
the height adjustment screw 4 of the Guide No.7 (TG7) 3
until tape slack is removed.

3) Playback a tape in normal mode. Confirm that tape slack dose

not occur in between the guide No.7 (TG7) 3 and capstan 2.
(Specification = 0.5 mm or less) If the tape slack of more than
0.5 mm is found, turn the height adjustment screw 4 until the
slack is 0.5 mm or less. Playback a tape in REV mode and
confirm that tape slack occurred in between the guide No.6
(TG6) 1 and capstan 2 is 0.3 mm or less, the adjustment is
complete.

1) Playback the SW/OL standard tape (WR5-2D) in REV mode.

Confirm that pitches between the peaks of the waveform are
equally spaced for 5 seconds or longer.
The pitches are not equally spaced, perform section “2-4-2.
Tape Path Adjustment” and section “2-4-3. No.7 Guide (TG7)
Adjustment”.

2) Playback the SW/OL standard tape in CUE mode.

Confirm that pitches between the peaks of the waveform are
equally spaced for 5 seconds or longer.
The pitches are not equally spaced, perform section “2-4-2.
Tape Path Adjustment”.

1) Playback the SW/OL standard tape.
2) Eject the tape once, insert and load the tape.
3) Start playing back the tape and confirm that the RF waveform

builds up in three seconds with flat envelope. Confirm at this
time that tape slack dose not occur near pinch roller.

4) Playback the tape in CUE/REV and FF/REW modes respec-

tively. Confirm that the RF waveform builds up in three sec-
onds with flat envelope. Confirm at this time that tape slack
dose not occur near pinch roller.

5) Repeat the check items 2) to 5) again.

1) Insert a thin video tape such as P5-120MP. Playback the thin

tape. Confirm that there is no clearance or curl of 0.3 mm or
more at the following points: Upper flange of guide No.3, up-
per flange of guide No. 6, upper and lower flanges of guide
No.7.

2) Confirm that there is no clearance or curl of 0.3 mm or more at

each tape guide when the FF button is pressed from the play-
back mode to enter the CUE mode, and when the REW button
is pressed from the playback mode to enter the REV mode.
