(On Automatic control)
Inside PATTERN is used when W/B is controlled. Connect to
auto controller or push Adjustment R/C POWER-ON -> Enter
the mode of White-Balance, the pattern will come out.
●
Auto-control interface and directions
(1) Adjust in the place where the influx of light like floodlight
around is blocked. (Illumination is less than 10ux).
(2) Adhere closely the Color Analyzer ( CA210 ) to the module
less than 10cm distance, keep it with the surface of the
Module and Color Analyzer’s Prove vertically.(80~100°).
(3) Aging time
- After aging start, keep the power on (no suspension of
power supply) and heat-run over 5 minutes.
- Using ‘no signal’ or ‘full white pattern’ or the others, check
the back light on.

■After enter Service Mode by pushing “ADJ” key,
■Enter White Balance by pushing “►” key at “7. White Balance”.
※
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. And Mechanical Power Switch must be set “ON”.
