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= 20/9 * (hours used in Normal mode) + 5/3 * (hours
used in Eco mode) + 20/13 * (hours used in SmartEco)+1 * (hours used in LampSave)
See "Setting Lamp mode eco function as Economic or SmartEco mode"
below for more information on Economic mode.
The lamp hour in Economic, SmartEco and LampSave is calculated shorter of that in
Normal mode. That is, using the projector in Economic, SmartEco or LampSave mode
helps to extend the lamp hour.
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.
