O
Operate the Zero-calibration of the CA-100, then stick sensor
to PDP module surface when you
make adjust ment .

For manual adjustment, it is also possible by the following
sequence.
(1) Select WHITE PATTERN of HEAT RUN mode by pressing
POWER ON KEY on service remote control then
operate HEAT RUN more than 15 minute.
(2) Supply 216Gray Level, 50% size length and breadth signal to
RGB input. (Refer to Fig 2)
(3) W/B adjustment must be adjusted only High Light and then
save the adjustment value with Y Key.
(4) To adjust High Light, stick sensor to 216 Gray Level (or 105-
115 Cd/m 2 ) Pattern, press ADJ Key on R/C for adjustment
and press T , U on R/C in adjustment mode to select R-L or G-
L, press VOL +, - Key and adjust it until color coordination
becomes as below.
X: 0.275±0.003, Y: 0.280±0.003
Color temperature: 11,500°K±500°K
(5) Exit adjustment mode using Y Key.
