9-3. 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) In case of PDP: Measure and adjust after sticking the
Color Analyzer (CA-100+, CA210 ) to the side of the
module.

(3) Aging time
- After aging start, keep the power on (no suspension of
power supply) and heat-run over 15 minutes.
- In case of PDP, keep white pattern using inside pattern.
- In case of LCD, using ‘no signal’ or ‘full white pattern’ or
- In case of LCD, using ‘no signal’ or ‘full white pattern’ or
the others, check the back light on.
