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.
