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)

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  /  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.

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 or remote control.

Using Economic /Smart Eco mode will reduces system noise and power consumption.

Setting the projector in Economic/Smart Eco mode also extends the lamp operation 
life. To set
