Functions in Service Mode
EXTRA OPTION
"EXTRA OPTION" is added to the MENU.
CUT OFF
Sets the display ON/OFF for each color (R, G, B).
3DCMS
Sets ON (Valid) / OFF (Invalid) of 3DCMS.
SELF CHECK
Displays SELF CHECK.
CW INDEX
When the color wheel is replaced, adjusts it with LEFT and RIGHT buttons.
a. Display the test pattern (Red & Blue pattern).
b. Confirm whether there is a horizontal line.
c. 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".)
d. 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".)
e. Set the mean value (omission below decimal point) of "A" and "B" to the CW INDEX setting value.
POWER ON SHUTTER
# OPEN: Opens the shutter when power ON.
# CLOSE: Closes the shutter when power ON.
POWER OFF SHUTTER
# IGNORE: Does not control the shutter when power OFF.
# OPEN: Opens the shutter when power OFF.
# CLOSE: Closes the shutter when power OFF.
MODEL
Set it when the A-P.C.Board is replaced.
# If replacing A-P.C.Board (assembly), set MODEL.
* Never set it to a model name different from the model that installs the new A-P.C.Board. If a different model name is set, it becomes impossible to output normal pictures after the next startup.
* When a new A-P.C.Board is installed without maintenance of adjustment data, it is required to adjust the color wheel.
ACF
Executes ACF setting/operation.
# FILTER SETUP: Sets the interval time of automatic rewinding of the filter.
# ROLL: Rewinds the filter once compulsorily.
CLOG SENSOR CALIBRATION
Execute the sensor calibration when EEPROM (IC3103 or IC3104) / A-P.C.Board or Airflow sensor (CF1302) is replaced.
* Make the main unit to the assembled state without fail, set the projector to the floor installation, and calibrate.
* If the projector installed at an elevation of 1 400 m or higher sea level, be sure to set the HIGH ALTITUDE MODE sub-menu in PROJECTOR SETUP menu to ON, and attempt the calibration.
When OK is selected and ENTER button is pressed, the calibration is executed.
# When the calibration is started, the screen becomes whole magenta.
# While calibrating, all lamps will light (DUAL mode).
# Do not switch OFF the projector while calibrating.
# When the magenta screen will disappear in approx. 15 minutes and it returns to the normal screen, the calibration is completed.
# Turn the POWER switch OFF and turn ON it again, then confirm whether to operate normally.
Ye MODULATE Addition
When the PICTURE MODE menu is displayed, it is enabled to be adjusted with the ENTER button.
# ON: Validates Ye MODULATE function.
# OFF: Invalidates Ye MODULATE function.
ADVANCED MENU Addition
The following 4 items are added to the ADVANCED MENU.
1. FRAME LOCK
When the input signal is RGB, FRAME LOCK is added.
2. 480i SD
When non-standard signal of 480i/576i is inputted (AV amplifier, etc.), synchronization might be disordered according to connected equipment. In this case, set 480i SD to ON.
3. 480p OS
When 480p/576p is received, aliasing noise (longitudinal striated beat noise) might be generated according to connected equipment. In this case, set 480p OS to ON. However, the resolution decreases a little.
4. HPLL
When non-standard signal of VIDEO/S-VIDEO is inputted (VCR, VHD, etc.), horizontal synchronization might be disordered
according to connected equipment. In this case, set HPLL to OFF.
STATUS Addition
The following items are added to the STATUS sub-menu in PROJECTOR SETUP menu.
1. APPROXIMATE TIME
Prediction remainder time of the filter in ACF
2. FPGA VERSION

Interlock Function
To ensure safety, the protection circuit of the main unit functions, and this projector becomes operation halt condition (a part of circuit is energizing) when the lamp unit cover is removed or installed incorrectly.
When servicing, install the lamp unit cover in former position when energizing with the upper case removed.
DISASSEMBLING PROCEDURE 
Removal of Upper Case
(1) Turn the lens cover counterclockwise and remove.
(2) Remove the projection lens.
1. Fully turn the projection Lens counterclockwise.
2. While pressing the lens release button, turn the projection lens counterclockwise in addition.
3. Remove the projection lens.
(3) Loosen the 1 screw until it idles, then remove the lamp unit
cover.
Note:
The lamp unit cover is connected to the main unit with the connector. Be careful when removing it.
(4) Unscrew the 5 screws and remove the upper case.
Note:
Confirm the lens release button actuates correctly when you reassemble the upper case as it was.
