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.

Using
Economic
mode reduces system noise and power consumption by 20%. If the

projected pictures.

set
Economic
mode, go into the

Light Source
Adjustments

Light Source Mode Selection
menu and press / .

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
