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
= 1 (hours used in
Low
mode) + 4/3 (hours used in
Standard
mode)
See
"Setting Lamp mode as Low"
below for more information on Low mode.
The lamp hour in
Low
mode is calculated as 3/4 of that in
Standard
mode. That is, using the projector in
Low
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

information appearing on the menu.

You can also get the lamp hour information on the
INFORMATION
menu.
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 mode as Low
Using
Low
mode reduces system noise and power consumption by 20%. If the
Low
mode is selected, the light output
will be reduced and result in darker projected pictures.
Setting the projector in
Low
mode also extends the lamp operation life. To set
Low
mode, go into the
SYSTEM
SETUP: Advanced

Lamp Settings
>
Lamp mode
menu and press / .

If this mode is frequently switched, the lamp may be deteriorated.
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.
To set
Auto Power Off
, go into the

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
