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.
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 mains plug into the mains socket 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.
