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 menu.

•Setting Lamp Power 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 life. To set Economic mode, go to the Advanced Setup > Lamp Settings > Lamp Power menu and press / .

•Setting Auto Off

This function allows the projector to turn off automatically if no input source is detected after a set period of time.

To set Auto Off, go to the System Setup > Auto Off menu and press / to select a time period. 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.
