Extending lamp life
The projection lamp is a consumable item that normally can last up to 3000-4000 hours 
with proper usage. To keep the lamp life as long as possible, you can do the following 
settings via the OSD menu.
•  Setting Lamp Mode 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 lamp operation life. To set 
Economic mode, go into the SYSTEM SETUP: Advanced > Lamp Settings > 
Lamp Mode 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 lamp life.
To  s e t  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.
