Adjustment remocon, 801GF(802B, 802F, 802R) or
MSPG925FA pattern generator
(It can output 480i/1080i horizontal 100% color bar pattern
signal, and its output level must setting 0.7V±0.1V p-p
correctly)

* You must make it sure its resolution and pattern cause every
instrument can have different setting
5-3. Adjustment method 480i Comp1,
Adjust 1080p Comp1/RGB
(Factory adjustment)
(1) ADC 480i Component1 adjustment
- Check connection of Component1
- MSPG-925FA ==> Model: 209, Pattern 65
- MSPG-925FA ==> Model: 209, Pattern 65
(2) Set Component 480i mode and 100% Horizontal Color Bar
Pattern(HozTV31Bar), then set TV set to Component1
mode and its screen to “NORMAL”
mode and its screen to “NORMAL”
(3) ADC 1080p Component1 / RGB adjustment
- Check connection both of Component1 and RGB
- MSPG-925FA ==> Model: 225, Pattern 65
- MSPG-925FA ==> Model: 225, Pattern 65
(4) Set Component 1080p mode and 100% Horizontal Color
Bar Pattern(HozTV31Bar), then set TV set to Component1
mode and its screen to “NORMAL”
