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= 20/9 * (hours used in Normal mode) + 5/3 * (hours used in Eco mode) + 20/13 * (hours used in SmartEco)+1 * (hours used in LampSave) See "Setting Lamp mode eco function as Economic or SmartEco mode" below for more information on Economic mode. The lamp hour in Economic, SmartEco and LampSave is calculated shorter of that in Normal mode. That is, using the projector in Economic, SmartEco or LampSave 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 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 eco function as Economic or SmartEco 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 / . . The lamp modes are defined as the chart below. Lamp mode Description Normal Economic SmartEco LampSave 100% lamp brightness. Saves 20% lamp power consumption. Saves up to 80% lamp power consumption depending on the content brightness level and keeps the image as bright as it is in normal mode. Saves up to 80% lamp power consumption to offer the longest lamp life. 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. 60 Maintenance

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= 20/9 * (hours used in Normal mode) + 5/3 * (hours used in
Eco mode) + 20/13 * (hours used in SmartEco)+1 * (hours used in LampSave)
See
"Setting Lamp mode eco function as Economic or SmartEco mode"
below for more
information on Economic mode.
The lamp hour in Economic, SmartEco and LampSave is calculated shorter of that in
Normal mode. That is, using the projector in Economic, SmartEco or LampSave mode
helps to extend the lamp hour.
To obtain the lamp hour information:
1.
Press
Menu/Exit
and then press
/
