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 eco function as Economic or SmartEco 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 highlighted.
2. Press to highlight Lamp Settings and press Mode/Enter. The Lamp Settings
page displays.
3. You will see the Equivalent lamp information displaying on the menu.
4. To leave the menu, press Menu/Exit.
You can also get the lamp hour information on the INFORMATION menu.
