Figure 9.
(1) Fig. 9 (A):
If the black horizontal line moves down
slowly, turn V-hold knob counterclockwise
to have a proper sync.
Fig. 9 (B):
If several horizontal lines appear at random,
turn V-hold knob clockwise to have a proper

(1) Connect pattern generator
(PM5508) to the unit.
(2) Set antenna input
to about 70 dB.
(3) Set the pattern to
"GRAY SCALE".

Figure 10.
(1) Turning RF-AGC (R209) clockwise will
produce noise in picture,
(2) Turning RF-AGC (R209) counterclockwise
will remove such noise; but the picture,
then, moves a little to right and its
brightness somewhat lessens.
Then, for proper adjustment:
Turn RF-AGC fully clockwise to produce
noise, turn it back gently to remove the
noise and stop just at a point where no
phenomenon such as (2) arises.
