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 light source brightness.
[REF. LIGHT MODE]
Three [REF. LIGHT MODE] options can be selected according to the purpose of use. You can also
adjust output power and change luminance (brightness).
This can also be used to adjust the brightness between the different projectors when using a com-
bination of multiple projectors.

• When [WALL COLOR] is set to [WHITEBOARD], [REF. LIGHT MODE] cannot be selected.
• If [CONSTANT BRIGHTNESS] is set to [ON], then [REF. LIGHT MODE] and [REF. LIGHT ADJUST] cannot be selected.
NORMAL This is the standard mode.

The output of each [REF. LIGHT MODE] can be adjusted in 1% increments and saved.

ON Maintains the brightness that is in effect at the time [ON] is selected. Unless [OFF] is
selected, the same settings will remain in effect even when the projector is turned
off.
• To re-adjust the brightness, first turn this setting [OFF] before making further
adjustments.
