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. 

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  /

 to highlight the SYSTEM SETUP: Advanced 

menu.

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 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 signal 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 > Operation Settings > 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.
