5. Verify that the horizontal lines on the top and
bottom of cross-hatched area of the monoscope
signal are horizontal and linear.
6. Turn RV916, RV964 and RV969, the horizontal
green linearity variable resistors (H.G
on the D-board, to obtain an optimum horizontal
linearity.
Then turn the horizontal green amplitude
variable resistor (H.G SIZE VR) to set horizontal
amplitude to 15.6 frames.
Note: The horizontal position indicator of the
monoscope signal must be positioned at
the center by adjusting
the
horizontal green center position variable
resistor (V.G CENT VR) in advance.

7. Input cross hatch signal.
Turn vertical green (V.G) and horizontal green
variable resistors and make
adjustments according to the following steps :
(Adjustment procedure)
1. [BOW] [SKEW] [CENT (center position)
2. [PIN (pin warp) [SUB BOW] [BOW]
3 . [KEYS (trapezoid) [SUB SKEW] [SKEW]
4. [M.WAVE (middle sine wave warp)
[WAVE-A (upper and lower sine wave warp)
[WAVE-U (upper sine wave warp)
For vertical (V) only.
5. [V-M.PIN (vertical middle pin warp)
[V/WING (vertical wing warp)
For vertical (V) only.
6 . [H-M.PIN (horizontal middle pin warp)
For horizontal (H) only.
