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 LIN VRs)
on the D-board, to obtain an optimum horizontal
linearity.
Then turn RV908, 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 RV902, 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
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] 4 [SKEW]
4 . [M.WAVE (middle sine wave warp) ] -
[WAVE-A (upper and lower sine wave warp) ] +
[WAVE-U (upper sine wave warp) ]
5 . [V-M.PIN (vertical middle pin warp) ] 4
[V/WING (vertical wing warp) ]
6 . [H-M.PIN (horizontal middle pin warp) ]
