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 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

"Setting the lamp

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 / . 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 50

for

details.

The following Lamp warning displays will remind you to change lamp 1 or lamp 2. Warning messages for lamp 1
are illustrated below.

Install a new lamp for optimal performance. If the

Brightest)" on page 45

), you may continue to

operate the projector until the 2950 hour lamp
warning appears.

The lamp has been in operation for 2950 hours. A
new lamp should be fitted to avoid the
inconvenience when the projector runs out of
lamp time.

is strongly recommended that you replace the
lamp at this age. The lamp is a consumable item.
The lamp brightness diminishes with use. This is
