1. Connect the monoscope signal to the ANALOG Y/G
input connector.
2. Press the SHIFT button to ON. [The LED (orange) on
top of the button turns on.]
3. To adjust the 4:3 mode of adjustment, press the 16:9
OFF button [to turn off the LED (orange)] to select the

on top of the button turns off.]
5. To select the NORMAL mode of adjustment, press the
UNDER SCAN button (
select the normal mode. [The green LED turns off.]
To select the UNDER SCAN mode of adjustment,
press the UNDER SCAN button (
position to select the under scan mode. [The green
LED turns on.]
6. Adjust the H CENTER data so that the horizontal
center of the picture comes to the horizontal center of
the screen.
7. Adjust the V CENTER data so that the vertical center of the
picture comes to the vertical center of the screen.
8. Connect the cross-hatch signal to the ANALOG Y/G
input connector.
9. Adjust the respective V SIZE, V LIN BAL, V LIN
AMP and H SIZE data so that the optimum picture is
obtained as shown in Fig. 1-8.
Note: Do not adjust the V SIZE data when adjusting the
MODEs 9, 13, 23 and 27.
10. Adjust the trapezoidal distortion and PIN distortion on
both sides of picture using the H KEY BAL, H KEY,
H PIN BAL and H PIN data respectively as shown in
Fig. 1-9.
11. Adjust the corner "S" distortion and the corner PIN
distortion on both sides of picture using the H CORS and
H COR PIN data respectively as shown in Fig. 1-10.
12. Repeat the above-described steps of the linearity
adjustment(2) until the optimum horizontal linearity
and vertical linearity are obtained.
