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.
To obtain the lamp hour information:
1. Press MENU/EXIT and then press  /  until the System Setup: Advanced menu is highlighted.

Extending lamp life
The projection lamp is a consumable item. 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. 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 life. To set Economic mode, go to the 
System Setup: Advanced > Lamp Settings > Lamp Mode menu and press MODE/ENTER. Press 
 to select Economic and press MODE/ENTER.
• 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  s e t  Auto Power Off, go to the System Setup: Basic > Operation Settings > Auto Power Off 
menu and press  /  to select a time period. The time period can be set for 3 minutes or 10 to 30 
minutes in 5-minute increments. If the preset time lengths are not suitable for your presentation, select 
Disable. The projector will not automatically shut down in a certain time period.
