Extending light source life

The light source is a consumable item that normally can last up to 10000-20000 hours with proper usage. To keep the light source life as long as possible, you can do the following settings via the OSD menu.

•Setting Light Source Mode Selection as Economic

Using Economic mode reduces system noise and power consumption by 20%. 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 light source operation life. To

set Economic mode, go into the SYSTEM SETUP: Advanced > Light Source Adjustments > Light Source Mode Selection menu and press / .

•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 light source life.

To set Auto Power Off, go into the SYSTEM SETUP: Basic > Operation Settings

>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.
