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

SmartEco ImageCare/SmartEco LampCare mode reduces system noise and power 

consumption by up to 70%, which adjusts image brightness dynamically. If the Economic, 

SmartEco ImageCare or SmartEco LampCare mode is selected, the light output 

will be reduced and result in darker projected pictures.
Setting the projector in Economic, SmartEco ImageCare or SmartEco LampCare 

mode also extends the lamp operation life. To set Economic, SmartEco ImageCare or 

SmartEco LampCare 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 set Auto Power Off, go into the SYSTEM SETUP: Basic > Operation Settings 
> Auto Power Off menu and press  / . 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.
