H-V adjustment
• For this adjustment, receive a crosshatch pattern, check whether adjustment is required or not, and then adjust.
This unit is equipped with a "16:9 mode" which identifies the input from S-video input and switches automatically to 16:9 screen
size for the full mode (squeeze signal) from a video camera or DVD. (Surface broadcasts remain "4:3".)
16:9 mode also requires adjustment. Please perform adjustment on the following basis.
The adjustment procedure is the same as for 4:3 mode.
Adjustment
1. V-HET (vertical amplitude)
2. V-LIN (vertical lilnearity)
3. V-SCR (vertical S-shape compensation)
4. V-POS (vertical position)
5. H-WID (horizontal amplitude)
6. H-POS (horizontal position)
7. H-PIN (vertical pin level)
1 Set to the 4:3 adjustment value.
