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:
Lamp Usage Time = (hours used in Normal mode) + (hours used in Economic mode)
Total (equivalent) lamp hour = 1.0 x (hours used in Normal mode) + 1.0 x (hours used in Economic
mode)
To obtain the lamp hour information:
1. Go to SYSTEM SETUP: ADVANCED > Lamp Settings and press OK. The Lamp Settings
page appears.
2. Press to select Lamp Timer and press OK. The Lamp Timer information is displayed.
You can also get the lamp hour information on the INFORMATION menu.
