-EEPROM setting mode
*) Since this product does not have OSD IC, OSD for adjustment is displayed by using GGF1416 at the time of
monitor adjustment.
A
[Operations]
To enter the setting mode, while keeping the EPRTEST terminal at "Low",
Flicker adjustment mode
Line adjustment 1 mode
Line adjustment 2 mode
Dimmer parameter setting mode
[ ↑ ↓ ] button: Used to select a desired adjustment item in each mode
[ ←→ ] button: Used to adjust the selected item
Notes:
B
1) The setting values are written in the EEPROM and then the read-out data is displayed on the screen.
WRITE and READ operations are processed by the block data of 16 bits.
The total bits for the settings depend on adjusting items.
2) For CS (Check Sum) items, when the settings are changed, the CS value is written in 8 bits by applying
the exclusive OR (XOR). The CS value is first written in the EEPROM and then the read-out data is displayed.
If the written data is different from the read-out data, the letter color for the read-out data is changed.
