[REF. LIGHT MODE]
Set this when you want to change the brightness of the projector or when you want to use the
projector in the energy-saving mode (→ page 41).
This can also be used to adjust the brightness between the different projectors when using a com-
bination of multiple projectors.

NOTE:
• 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.
TIP:
• Brightness normally decreases with use, but by selecting [CONSTANT BRIGHTNESS] mode, sensors inside the projector detect
brightness and automatically adjust the output, thereby maintaining a constant brightness throughout the life of the light module.
However, if output is already at its maximum, brightness will decrease with use.
For this reason, when using multi-screen projection, it is recommended to adjust the brightness to a slightly lower level, then
setting the [CONSTANT BRIGHTNESS] mode to [ON].
The picture becomes brighter than the [NORMAL] mode. However, the operating
noise and power consumption will also increase due to control of the cooling fan ac-
cording to the brightness. The life of the optical components may also be shortened
depending on the operating environment.
The light module luminance (brightness) will become 100% and the screen will
turn bright.
By controlling the brightness and fan speed according to the selected setting,
energy can be saved and motion noise and the power consumption can be lowered.
Brightness can be adjusted in 1% increments from 50 to 100%.
[CONSTANT BRIGHTNESS] mode will be canceled.
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.
