1. Adjustment item and a procedure
When the following parts are disassembled or exchanged, please adjust according to the table below.
1.1. Lighting Area Adjustment
1. 1. 1. Lighting area confirmation
1. Check if any shade is visible in the DMD effective display area.
* Make the projection environment as dark as possible, and project an all-white and all-black pattern (internal pattern) for this check.
* Change the "DUAL" "LAMP1" "LAMP2" on [LAMP SELECT], please check each.
2. When the Lighting area interferes with the effective area, adjust the Relay Lens Holder position.
1. 1. 2. Lighting area adjustment
1. Unscrew the one screw and free the RL-P.C.Board fixing bracket.
2. Open the adjustment cover to upper side.
3. Projection "All White" in internal test pattern. (Lamp select "DUAL" and Lamp power "NORMAL")
Adjust to after EEPROM data transmission is completed.

4. Loosen the 2 fixed screw, with a hexagon wrench (2.5 mm).
5. Adjustment screw ① coordinates the horizontal direction
of the Lighting area.
6. Adjustment screw ② coordinates the vertical direction
of the Lighting area.
7. When adjustment is completed, tighten two fixed screws.
8. Please assemble an adjustment cover and RL-P.C.Board
fixing bracket fittings as before.
1. 2. Color wheel index adjustment
1. Setting to Service mode, and select "Red-Blue" in internal test patterns.
2. Set to [DYNAMIC] of PICTURE MODE.
3. Select "CW INDEX" in "EXTRA OPTION" menu and adjust with ◀ ▶ buttons.
4. Confirm whether there is a horizontal line in red area and blue area.
5. If a horizontal line is in the red area, decrease CW INDEX setting value by 1 and record
the value where the horizontal line (in both red area and blue area) disappears.
(The recorded value is assumed to "A".)
6. If a horizontal line is in the blue area, increase CW INDEX setting value by 1 and record the value where
the horizontal line (in both red area and blue area) disappears. (The recorded value is assumed to "B".)
7. Set the mean value (omission below decimal point) of "A" and "B" to the CW INDEX setting value.
If there is no setting that horizontal line of both blue and red disappears, set it at the point where the line
in blue area is Inconspicuous.
8. Please cancel service mode, if adjustment is completed.
1. 3. Lens calibration
1. Select sub menu "LENS CALIBRATION" of main menu "PROJECTOR SETUP".
2. Because a confirmation message is displayed, select "OK".
3. The lens will move vertically and horizontally, and the limit value of the lens shift and home position are set automatically.
4. When the lens has been completely stopped, calibration is complete.
If the calibration has not been correctly executed, a message [INCOMPLETE] will appear.
In this case, please start again from step 1.
