This reorients your image for your type of projection. The options are: desktop front projection, ceiling rear projection,
desktop rear projection, and ceiling front projection.
NOTE: Selecting one of the other options than “Desktop Front” will force the “Keystone” mode to be “Manual".
Selecting Menu Language [Language]
You can choose one of 19 languages for on-screen instructions.
Setting Lamp Mode to Normal or Eco [Lamp Mode]
This feature enables you to select two brightness modes of the lamp: Normal and Eco modes. The lamp life can be
extended up to 3000 hours by using the Eco mode. Selecting Eco mode decreases fan noise compared to in Normal
mode.
Normal Mode ........ This is the default setting (100% Brightness).
Eco Mode .............. Select this mode to increase the lamp life (76% Brightness).
NOTE: If the projector is overheated in Normal mode, there may be a case where the Lamp mode automatically changes to Eco
mode to protect the projector. When the projector is in Eco mode, the picture becomes slightly darker. When the projector comes
back to normal temperature, the Lamp mode returns to Normal mode.
NOTE: When a picture is muted or there are no signals (blue or black screen), the Eco mode will be automatically selected in
"Lamp Mode."
