Lamp information
Getting to know the lamp hour
When the projector is in operation, the duration (in hours) of lamp usage is
automatically calculated by the built-in timer. The method of calculating the equivalent
lamp hour is as follows:
Total (equivalent) lamp hour
= 1 (hours used in Economic mode) + 4/3 (hours used in normal mode)
See "Setting Lamp Mode" below for more information on Economic
mode.
The lamp hour in Economic mode is calculated as 3/4 of that in Normal mode.
That is, using the projector in Economic mode helps to extend the lamp hour by 1/
3.
To obtain the lamp hour information:
1. Press Menu/Exit and then press / until the SYSTEM SETUP: Advanced
menu is selected.
2. Press to select Lamp Settings and press Mode/Enter. The Lamp
Settings page displays.
3. Select Lamp Information and press Mode/Enter.
4. You will see the Equivalent lamp hour information displaying on the menu.
5. To leave the menu, press Menu/Exit.
You can also get the lamp hour information on the INFORMATION menu.

you can do the following settings via the OSD menu or remote control.

operation life. To set Economic/SmartEco mode, go into the SYSTEM SETUP:
