J Replacing

1. Turn off the MAIN POWER switch according to the procedure 

“Switching the projector on/off” on page 19, and then disconnect the 
power cord plug from the wall outlet and check that the area around 
the lamp unit has cooled down.

2. Use a Phillips screwdriver to turn the lamp unit cover fixing screws at 

the bottom of the projector, and then remove the lamp unit cover.

3. Use a Phillips screw driver to loosen the two lamp unit fixing screws 

until the screws turn freely. Then hold the handle of the lamp unit and 
gently pull it out from the projector.

4. Insert the new lamp unit while making sure that the direction of 

insertion is correct, and then use a Phillips screwdriver to securely 
tighten the lamp unit fixing screw.

5. Install the lamp unit cover, and then use a Phillips screwdriver to 

securely tighten the lamp unit cover fixing screws.

J Resetting the LAMP RUNTIME

If the lamp usage time has passed 2 000 hours (when LAMP POWER has been set to NORMAL), the 
projector will switch to standby mode after approximately 10 minutes of operation. The resetting procedure 
should thus be completed within 10 minutes.

1. Insert the power cord plug into the wall outlet and then 

press the MAIN POWER switch.

2. Press the POWER button so that a picture is projected onto 

the screen.

3. Press the MENU button to display the menu screen, and 

then press the 

F or G button to select the OPTION menu.

4. Press the ENTER button, and then press the 

F or G button 

to select LAMP RUNTIME.

5. Press and hold the ENTER button for approximately 

3 seconds. The confirmation screen, “LAMP RUNTIME 
RESET.” is displayed and select OK.

6. Turn off the power.

  This will reset the cumulative usage time for the lamp 

unit to zero.

NOTE:
  Be sure to install the lamp unit and the lamp unit cover securely. If they 

are not securely installed, it may cause the protection circuit to operate so 
that the power cannot be turned on.

  Grip the handle when you remove the lamp unit. Some parts of the lamp 

unit are sharpened and may cause injury.
