(On Automatic control)
Inside PATTERN is used when W/B is controlled. Connect to
auto controller or push Adjustment R/C P-ONLY → 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 10 lux).
(2) Adhere closely the Color analyzer(CA210) to the module
less than 10 cm 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 'POWER ONLY' or the others, check
the back light on.
