- Because this is not a hot chassis, it is not necessary to use an isolation transformer. However, the use of isolation transformer will help protect test instrument.
- Adjustment must be done in the correct order.
- The adjustment must be performed in the circumstance of 25±5°C of temperature and 65±10% of relative humidity if there is no specific designation.
- The input voltage of the receiver must keep 100~220V, 50/60Hz.
- Before adjustment, execute Heat-Run for 15 minutes at RF no signal.

ADC Process
Required Equipments
- Remote controller for adjustment
- MSPG-925F Pattern Generator
- Convert to RGB PC in Input-source
- Input the PC 1024x768 @ 60Hz 1/2 Black & White
- Pattern (MSPG-925F model:60, pattern:54) into RGB.
Adjust by commanding AUTO_COLOR_ADJUST(0xF1) 0x00 0x02
instruction.
Confirmation
- Confirm whether "0xF3 (offset), 0xF4 (gain)" address of EEPROM "0xBC" is "0xAA" or not.
- If "0xF3", "0xF4" address of EEPROM "0xBC" isn’t "0xAA", adjust once more
- We can confirm the ADC values from "0x06~0x0B"addresses in a page "0xBC"
After enter Service Mode by pushing "ADJ" key,
execute "Auto-RGB" by pushing "_" key at
"Auto-RGB"
Component input ADC.
Component Gain/Offset Adjustment7
- Convert to Component in Input-source
- Input the Component ( Which has 720p@60Hz YpbPr signal : 100% Color Bar (MSPG-925F Model : 217 / Pattern:65 ) into Component.
- Adjust by commanding AUTO_COLOR_ADJUST (0xF1)0x00 0x02 instruction.
Confirmation
- Confirm whether "0xF3 (offset), 0xF4 (gain)" address of EEPROM "0xBC" is "0xAA" or not.
- If "0xF3", "0xF4" address of EEPROM "0xBC" isn’t "0xAA",adjust once more
- Can confirm the ADC values from "0x06~0x0B"addresses in a page "0xBC"
After enter Service
Mode by pushing "ADJ" key, execute "Auto-RGB"by pushing
"_" key at "Auto-RGB"
