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 Economic mode) + 4/3 (hours used in normal mode)

See "Setting Lamp mode eco function as Economic or Smart Eco mode" below for more information on Economic 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.
