Extend mode (EXT OPTION menu)
This projector has extend mode "EXT OPTION" menu in addition to standard on-screen menus.
This mode has Self-Check function, Test Pattern and other functions for Service.
How to access Extend mode 
1. When the projector is power ON, press "POWER" button on the main unit or remote control unit to display "POWER OFF" confirmation screen.
2. Press the " RIGHT " button to select "CANCEL" in the "POWER OFF" confirmation screen.
3. On the main unit or remote control unit, press the buttons in order of " UP ", " DOWN ", " UP ", " DOWN " and "ENTER".
4. When "MENU" button is pressed at the "EXT OPTION" mode, Extend-mode is closed.
EXT OPTION Menu and Functions
Setting the cooling fan motor rotation speed.
Switching ON "FAN FULLMODE", the rotation level of the fan becomes high-speed rotation (fixed). Moreover, when "FAN FULLMODE" is ON, changing "HIGH ALTITUDE MODE" in OPTION menu becomes impossible (setting FAN FULLMODE is given priority more than HIGH ALTITUDE MODE).
Setting AUTO SETUP mode.
- NORMAL: Dot clock is adjusted strictly.
- SPECIAL: Dot clock is adjusted roughly.
# Do not usually change initial setting (NORMAL)
(1) - Software Version (MM : Main microprocessor, F:FPGA )
# FPGA (Field Programmable Gate Array)
(2) - Input signal Display ( [NO-SYNC] is displayed when there is no input signal).
(3) - Input Horizontal/Vertical signal frequency (For the RGB/YPBPR Input only)
(4) - The temperature abnormality check ("NG" is displayed for any abnormality)
(5) - Temperature around the air intake port/exhaust port and Filter sensor (deg C/A/D conversion value)
(6) - Filter sensor Difference Correction (A/D conversion) Value
(7) - Rotation check of Intake fan / Lamp fan / Iris fan (Displays "NG" when Fan is abnormal condition)
(8) - Iris condition check (Abnormal condition = "NG")
(9) - Lamp condition check (Abnormal condition = "NG")
(10) - Lamp cover installation check (Abnormal condition="NG")
(11) - Displays the projector cumulative usage time
(12) - Cumulative usage time (actual time) and Number of LAMP ON times "Current number : Last reset : Reset of last but one"
(13)- Displays the serial number of the projector.
(14)- Software Version (SM : Sub microprocessor, IM : IRIS control microcomputer)
(15)- Gamma, Color Unevenness and Crosstalk correction data check (Whether data are stored in the flash ROM)
(16)- Thermo sensor (Intake Air / Exhaust Air / Filter Air) measurement value when thermal shutdown
(deg C/A/D conversion value)
(17)- Rotation check of Exhaust fan and Power fan (Displays "NG" when Fan is abnormal condition)
# When detected abnormal temperature around the air intake port / air exhaust port / LCD block, TEMP indicator turned on. If arriving at the critical temperature, the power supply will shut down automatically (thermal shutdown) and the indicator will flash
18)- Lens memory operation abnormality check (Abnormal condition = "NG")
(19)- Judgment for Replacement Time of Lamp (Cumulative Usage more than 4000H is "NG")
# Warning of the lamp cumulative usage time and shutdown use the conversion time for LAMP POWER "NOMAL".
(20)- The number of times that carried out reset of "LAMP RUNTIME"
(21)- Cumulative usage time (conversion for LAMP POWER "NOMAL" time) and Number of LAMP ON times "Current number : Last reset : Reset of last but one"
Display version of each software and each data.
To enter the flicker adjustment mode.
Note: If replacing the optical parts (Optical block) or A-P.C.Board, adjust to flicker is minimum according to the "Flicker adjustment".
Air filter unit
# Clean the Air filter after every 100 hours of usage.
# A replacement air filter kit (TXFKN01RYNZP) is provided with a replacement lamp unit, ET-LAA410
1. If the air filter is excessively dirty, the internal temperature of the projector increases and may cause malfunction.
2. Do not use the projector without attaching the air filter.
3. The air filter should be replaced when cleaning is ineffective and when replacing the lamp unit.
Replacement procedure for lamp unit
1. Confirm that the lamp unit is cooled down completely. (More than 1 hour has passed after main power is off.)
2. Open the top cover in the direction of the arrow.
3. Lamp cover fixing screw is loosened all the way and remove "Lamp.

4. Use a Phillips screwdriver to unscrew the lamp unit fixing screws (2 screws) until loose.
5. Hold the handle of the lamp unit and with the lamp unit lock held in the direction of the red arrow, carefully pull it out of the projector unit in a vertical motion.

6. Insert the new lamp unit in correct direction. Tighten the two lamp unit fixing screws securely with a Phillips screwdriver.
# Press down on the A part firmly when inserting the lamp unit.
7. Attach the lamp cover, and tighten the two lamp cover fixing screws securely with Phillips screwdriver.
8. Close the top cover of the projector.
Reset procedure of the lamp use time
1. Insert the power plug into a power outlet, and press the <ON> side of the <MAIN POWER> switch to turn on the power.
