EnglishLamp information
Getting to know the lamp hour
When the projector is in operat ion, 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) +  3/2 (hours used in normal mode)
See Setting Lamp mode as Economic  below for more information on Economic mode.
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 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 2000-3000 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  / .
Setting Auto Power Off
This function allows the  projector to turn off automatically  if no input source is detected 
after a set period of time to prevent unnecessary waste of lamp life.
To  s e t   Auto Power Off , go into the SYSTEM SETUP: Basic  > Auto Power Off menu and 
press  / . The time period can be set from  5 to 30 minutes in 5-minute increments. If the 
preset time lengths ar e not suitable for your  presentation, select Disable. The projector will 
not automatically shut down  in a certain time period.
