3. Judgement
It is OK with C level or higher when ① to ⑤ focus balance is set.
A: Each dot can be seen clearly. (There is a gap between dots.)
B: Each line can be seen clearly. (There is a gap between lines.)
C: Each line can be recognized but border of each line is not clear.
D: Each line cannot be recognized.
In case of D, please adjust the lens tilt adjustment.
1. 2. 3. Lens Tilt adjustment
1. Rotate focus ring to NEAR direction and stop it where it focuses at last of 4 corners ( ①②③④).
2. Measure the distance of best focus points and the screen for 3 locations other than last focused corner.
* Define that Maximum measured distance as X1st and 2nd distance as X2nd.
3. Make the shim adjustment based on the measured value and the chart below.
*0.3mm thick shim is set as the factory default. Depending on the neccessity,
combine 0.1mm and 0.3mm shim for the adjustment.
(1) In case of " X1st-X2nd ≧ 0.2X1st "
(2) In case of "X1st-X2nd < 0.2X1st" < Tilt for H direction >
(3) In case of "X1st-X2nd < 0.2X1st " <Tilt for V direction>
4. Whne the adjustment is finished, reconfirm it with procedure in "1.2.2 focus confirmation".

1. 3. Color wheel index adjustment
1. Go to the Serviceman mode and select "Red-Blue" in internal test patterns.
2. Select "CW INDEX" in "EXT OPTION" menu and adjust with
buttons.
3. Confirm if there is a hilizontal line in red and blue area in the test pattern.
4. When there is a holizontal line in red area, set the value to lower 1 by 1 to find the value where the line in red and
blue disappears. ---------- (The value is named as A.)
5. When there is a holizontal line in blue area, set the value to higher 1 by 1 to find the value where the line in red and
blue disappears. ---------- (The value is named as B.)
6. Set the average value of A and B as CW INDEX value. (Omit the figures after the decimal fractions.)
Note: If there is no value to eliminate the line in red and blue both at the same time,
set it at the point where the line in blue area is hardest to see.
1. 4. EEPROM data transfer
1. 4. 1. Required equipments
1. Computer : Use it for the transfer of backup data.
2. Communication cable : D-sub 9pin (male/female RS-232C straight)
3. Service Software : ［DataLogBackup tool］ Service software is downloaded from the projector service homepage.
