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= 2.00 (hours used in Normal mode) + 1.67 (hours used
in Eco mode) + 1.00 (hours used in SmartEco mode)
See "Setting Lamp Mode" below for details.
The lamp hour in Economic/SmartEco is calculated shorter of that in Normal
mode. That is, using the projector in Economic/SmartEco mode helps to extend
the lamp hour.
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.
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 or remote control.
Setting Lamp Mode
Using Economic/SmartEco mode will reduces system noise and power
consumption. If the Economic/SmartEco mode is selected, the light output will be
reduced and result in darker projected pictures, the projector protected for longer
working life.
Setting the projector in Economic/SmartEco mode also extends the lamp
operation life. To set Economic/SmartEco mode, go into the SYSTEM SETUP:
Advanced > Lamp Settings > Lamp Mode menu and press / . .
