Extending Lamp Life; Timing Of Replacing The Lamp - BenQ SP920 - XGA DLP Projector User Manual

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 menus.
• Setting Lamp Mode as Dual-Reliable
Compared to Dual-Brightest mode, using Dual-Reliable mode reduces system noise and power consumption. If
the Dual-Reliable mode is selected, the light output for the individual lamp will be reduced.
Setting the projector in Dual-Reliable mode also extends the individual lamp operation life. See
mode" on page 39 for how Dual-Reliable mode is set.
• 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
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
details.
