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 Low mode) + 4/3 (hours used in Standard mode)
See "Setting Lamp mode as Low" below for more information on Low mode.
The lamp hour in Low mode is calculated as 3/4 of that in Standard mode. That is, using the projector in Low 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 is displayed.
3. You will see the Equivalent lamp hour information appearing 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 Low
Using Low mode reduces system noise and power consumption by 20%. If the Low mode is selected, the light output
will be reduced and result in darker projected pictures.
Setting the projector in Low mode also extends the lamp operation life. To set Low mode, go into the SYSTEM
SETUP: Advanced > Lamp Settings > Lamp mode menu and press / .
• When this mode is switched, the projected images may flicker.
• If this mode is frequently switched, the lamp may be deteriorated.
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 set 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 are not suitable for your
presentation, select Disable. The projector will not automatically shut down in a certain time period.
