Extending lamp life
The projection lamp is a consumable item that normally can last up to 2000-3000 hours with proper usage. To
keep the lamp life as long as possible, you can do the following settings via the OSD menus.
•
Setting Lamp Mode as Economic
Using Economic mode reduces system noise and power consumption. If the Economic mode is selected, the light
output will be reduced and result in darker projected pictures.
Setting the projector in Economic mode also extends the lamp operation life. To set Economic mode, go into the
SYSTEM SETUP: Advanced > Lamp Settings > Lamp Mode menu and press / to select Economic.
•
Setting Auto Power Off
This function allows the projector to turn off automatically if no input signal is detected after a set period of time
to prevent unnecessary waste of lamp life.
To set Auto Power Off, go into the SYSTEM SETUP: Basic > Auto Power 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.
Timing of replacing the lamp
When the LAMP indicator light is red or a message appears suggesting it is time to replace the lamp, please install
a new lamp or consult your dealer. An old lamp may cause a malfunction in the projector and in some instances
the lamp may explode.
The LAMP indicator light and TEMPerature indicator light will light up if the lamp becomes too hot. Turn
the power off and let the projector cool for 45 minutes. If the LAMP or TEMPerature indicator light still
lights up after turning the power back on, please contact your dealer. See
"Indicators" on page 48 for
details.
The following Lamp warning displays will remind you to change the lamp.
