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 as Economic"
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
menu is highlighted.
2. Press
page displays.
3. You will see the Equivalent lamp hour 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.
Extending lamp life
The projection lamp is a consumable item that normally can last up to 3000-4000 hours with
proper usage. To keep the lamp life as long as possible, you can do the following settings
via the OSD menu.
Setting Lamp mode as Economic
Using Economic mode reduces system noise and power consumption by 20%. If the
Economic mode is selected, the light output will be reduced and result in darker projected
pictures.
Setting the projector in Economic mode also extends the lamp operation life. To set
Economic mode, go into the SYSTEM SETUP: Advanced > Lamp Settings > Lamp
mode menu and press
