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-Brightestmode, using Dual-Reliablemode reduces system noise and power consumption. If the Dual-Reliablemode is selected, the light output for the individual lamp will be reduced.

Setting the projector in Dual-Reliablemode also extends the individual lamp operation life. See "Setting the lamp mode" on page 39 for how Dual-Reliablemode 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.
