If the pressure against the
tape at TG-2 is too much,
the waveform becomes as
shown in the upper figure.
(NG)
The RF envelope waveform is flat.

Perform the following steps (9) to (16) only if the
specification 10 was not satisfied.
(9) Turn off the power, then remove the HR2-
1A.
(10)Reset Bit-3 of the DIP switch S802 on the
SS-95 board to OFF (lower side).
(11)Set the alignment tape HR2-1B and put a
weight (about 1 kg) onto it.
(12)Turn on the power, then play back the HR2-
1B (00:00 to 20:00) in the PLAY mode.
(13)Rotate the tracking VR (RV1001/SS-95
board) clockwise to set the center of the RF
envelope waveform to 80 % of the maximum
output level, then check that the waveform
satisfies the specification 11.
(14)Slightly rotate the height adjustment nut of
TG-2 a little clockwise.
(15)Check again that the waveform satisfies the
specification 11.
If specification 11 is not satisfied, perform
the adjustment (4) of step 1 and later again.
(16)Perform steps (1) to (6) again to check that
the specification 10 is satisfied. If the specifi-
cation 10 is satisfied, proceed to step (7). If
not, perform the following steps
1
to
4
.
1
Turn off the power, and remove the HR2-
1A.
2
Set the HR2-1B, and put a weight (about
1 kg) onto it.
3
Reset Bit-3 of the DIP switch S802 on
the SS-95 board to OFF (lower side).
4
Turn on the power, and perform (2) of
step 1 and later.
