6-2. Video Amplitude Signal: No.23 (1600*1200@85Hz) Window Pattern

(H:33% V:33%)

1) Receive signal 23.

2) Open Menu (S), TAG7.

3) Adjust "+", "-" SW so that video amplitude at TP-R (R GAIN) on the CRT PWB is set to 45 Vp-p (+0V/ -1V).

4) When the indicated value of the video amplitude is not 45 Vp-p(+0V/ -1V) with Gain data maximum,

increase the R Gain values.

5) Adjust "+", "-" SW so that video amplitude at TP-G (G GAIN) ,TP-B (B GAIN) on the CRT PWB is set to

45 Vp-p(+0V/ -1V)

6) Push "EXIT" SW

※ When adjusting video amplitude, move cursor to desired function and push PROCEED button to

hide the OSM menu. Adjustment can be made with OSM menu hidden. OSM menu must be

hidden since its amplitude will appear on the wave form.
