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:
Equivalent lamp hour
= 1 (hours used in Economic mode) +4/3 (hours used
in normal mode)
See "Setting Lamp Power as Eco." below for more
information on Eco. mode.
To obtain the lamp hour information:
1. Press MENU and then press / until the
Advanced Setup menu is highlighted.
2. Press to highlight Lamp and press ENTER. The
Lamp page displays.
3. Highlight Lamp Hours and press ENTER to
display the Lamp Hours information page.
4. To leave the menu, press MENU.
About Lamp Rest Rate:
Lamp Rest Rate shows the percentage of the lamp rest
life. The method of calculating the rate is as follows:
Rest Rate = [1 - (Total Lamp Hours /4000)] x 100%
Extending lamp life
The projection lamp is a consumable item that normally
can last up to 3000-4000 hours with proper usage. To
keep the lamp life as long as possible, you can do the
following settings via the OSD menu.
• Setting Lamp Power as Eco.
Using Eco. mode reduces system noise and power
consumption by 20%. If the Eco. mode is selected, the
light output will be reduced and result in darker
projected pictures.
Setting the projector in Eco. mode also extends the lamp timer automatic shutdown feature.
To set Eco. mode, go into the Advanced Setup > Lamp > Lamp Power menu and press /
.
• Setting Auto Off
This function allows the projector to turn off automatically if no input source is detected
after a set period of time.
To set Auto Off, go into the System Setup > Auto Off menu and press / . The time
period can be set from 5 to 30 minutes in 5-minute increments. If the preset time lengths are
not suitable for your presentation, select Disable. The projector will not automatically shut
down in a certain time period.
