5. Using On-Screen Menu
Using the Wall Color Correction [WALL COLOR]
This function allows for quick adaptive color correction in applications where the screen material is not white.
NOTE: Selecting [WHITEBOARD] reduces lamp brightness.
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 by using the ECO mode. Selecting ECO mode decreases fan noise when compared to NORMAL mode.

(→page 67)
• The projector is always in [NORMAL] for one minute after the lamp is turned on and while the POWER indicator is blinking green.
The lamp condition will not be affected even when [LAMP MODE] is changed.
• If there is no signal for about one minute, the projector will display a blue, black or logo background (depending on setting) and
go into [ECO].
The projector will return to the [NORMAL] mode once a signal is accepted.
• If the projector becomes overheated in [NORMAL] mode because of use in a high-temperature room, there may be a case where
the [LAMP MODE] automatically changes to [ECO] mode to protect the projector. This mode is called “forced ECO mode”. When
the projector is in [ECO] mode, the picture brightness decreases. The LAMP indicator’s steady light indicates the projector is in
[ECO] mode. When the projector comes back to normal temperature, the [LAMP MODE] returns to [NORMAL] mode.
Thermometer symbol [
] indicates the [LAMP MODE] is automatically set to [ECO] mode because the internal temperature is
too high.
