* CASE Cool
First adjust the coordinate far away from the target
value(x, y).
1) x, y > target
i) Decrease the R, G.
2) x, y < target
i) First decrease the B gain,
ii) Decrease the one of the others.
3) x > target, y < target
i) First decrease B, so make y a little more than the
target.
ii) Adjust x value by decreasing the R.
4) x < target, y > target
i) First decrease B, so make x a little more than the
target.
ii) Adjust x value by decreasing the G.
How to adjust
1) If G gain is adjusted over 172 and R gain and B gain
less than 192, Adjust is O.K.
2) If G gain is less than 172, increase G gain by up to
172, and then increase R gain and B gain same
amount of increasing G gain.
3) If R gain or B gain is over 255, Readjust G gain less
than 172, Conform to R gain is 255 or B gain is 255.
* CASE Medium / Warm
First adjust the coordinate far away from the target
value(x, y).
1) x, y > target
i) Decrease the R, G.
2) x, y < target
i) First decrease the B gain,
ii) Decrease the one of the others.
3) x > target, y < target
i) First decrease B, so make y a little more than the
target.
ii) Adjust x value by decreasing the R
4) x < target, y > target
i) First decrease B, so make x a little more than the
target.
ii) Adjust x value by decreasing the G
* After You finish all adjustments, Press “In-start” button
and compare Tool option and Area option value with its
BOM, if it is correctly same then unplug the AC cable.
If it is not same, then correct it same with BOM and
unplug AC cable.
For correct it to the model’s module from factory JIG
model.
* Push the “IN-STOP KEY” after completing the function
inspection.
