Free Waveform
If the free waveform
is not within the range in
Fig.
4-19,
perform
the following
adjustment.
(1) When there are no (or few) peaks on the free
waveform:
Turn height adjustment screw @ (Fig. 4-20)
slowly
clockwise
to
obtain
the range
in
Fig. 4-19.
,
(2) When there are too many peaks:
Turn
height
adjustment
screw
@
slowly
~ counterclockwise.
Note 1): Turn screw (a) slowly and observe the wave-
form movement every 30°.
2): When
screw
@) is turned, the tape running
height changes, and the tape may touch the
upper
or
lower
guide
flange.
Therefore,
when
performing
this adjustment,
observe
continuously with a dental mirror and make
sure that the tape does not touch the No.7,
8 guide flanges and ACE head lower flange.
If the tape touches No. 7, 8 guides before
the range in Fig. 4-19 is obtained, turn No. 7,
8 guides counterclockwise
and make space.
If it touches
the ACE
head
lower
flange,
turn No. 7, 8 guides clockwise.

Turn
No. .7 guide clockwise and make
the RF
output waveform exit 4cm.

5)
While observing the No. 8 guide and tape space
with a dental mirror, turn the No. 8 guide clock-
wise, and get rid of the space. (This can be done
more easily by turning until a curl appears, then
turning in the opposite direction just until the
curl is gone.)
6)
Check that the RF output waveform exit portion
is 4cm. If it has changed, make it 4cm with No. 7
guide. If No. 8 guide is tightened, the RF wave-
form changes and goes over 4cm, so turn No. 7
guide again and make it 4cm.
7)
Check again that there is no space between No. 8
guide and the tape.
8)
Loosen: No.

9)
Put into RVS mode and check No. 8 guide curl
and space with a dental mirror.
10) When there is curl at No. 8 guide in RVS mode,
turn No. 9 guide clockwise and adjust so that the
curl disappears.
When 'there is space, turn the
No. 9 guide counterclockwise and adjust so that
space is gone.
11) Check
that there is no
curl at No. 8 guide in
REV mode.
12) If there is curl at No. 8 guide in REV mode, turn
No. 9 guide clockwise to get rid of the curl. If
put into RVS mode
at this time, there will be
space, but this is OK.
