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 mode as Economic or SmartEco
Using Economic mode reduces system noise and power consumption by 30%. Using
SmartEco mode reduces system noise and lamp power consumption by up to 70%. If the
Economic or SmartEco mode is selected, the light output will be reduced and result in
darker projected pictures.
Setting the projector in Economic or SmartEco mode also extends the lamp operation

Lamp Settings > Lamp mode menu and press ◄/► until your desired mode is
selected.

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.
