(If not executed this step, the condition for W/B may be
different.)
(2) Push “Exit” key.
(3) Enter White Balance mode by pushing the ADJ key and select

the center of LCD module within 10cm of the surface
(5) Select each items (Red/Green/Blue Gain) using ▲/▼(CH +/-)
key on R/C..
(6) Adjust R/ G/ B Gain using ◄/►(VOL +/-) key on R/C.
(7) Adjust three modes all (Cool / Medium / Warm)
- For All model w/o LS345
Fix the one of R/G/B gain and change the others
-
For LS3450 model
Cool Mode
(i) Fix the one of R/G/B gain to 192 (default data) and
decrease the others.
( If G gain is adjusted over 172 and R and B gain less than 192 ,
Adjust is O.K.)
(ii) If G gain is less than 172, Increase G gain by up to 172,
and then increase R gain and G gain same amount of
increasing G gain.
(iii) 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
Medium / Warm Mode - Fix the one of R/G/B gain to 192
(default data) and decrease the others.
(8) When adjustment is completed, exit adjustment mode using
EXIT key on R/C.
※
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
▪
If it is LS345 Model.
※
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
