Interrelation of luminance and runtime
The projector can be operated at arbitrary brightness and duration of use by combining the settings of [MAX
LIGHT OUTPUT LEVEL], [LIGHT OUTPUT], and [CONSTANT MODE] in [BRIGHTNESS CONTROL SETUP].
Interrelation of luminance and runtime is as follows. Make the settings depending on your desired duration of use
and brightness of the projected image.
Values of the luminance and runtime are rough estimations.

Note
f The runtime may be shorter than the estimation due to the influence of characteristics of each light source, conditions of use, installation
environment, etc.
f The duration of use is referred to as the runtime when you use the projector successively. The duration of use is an estimated duration and
is not the warranty period.
f If the runtime exceeds 20 000 hours, replacement of the components inside the projector may be required. Consult your dealer for details.
[LIGHT OUTPUT]
Adjust the brightness of light source.
The setting is reflected when it is already set with "Initial setting (operation setting)" (x page 54) in the [INITIAL
SETTING] screen or with the [PROJECTOR SETUP] menu → [OPERATION SETTING]. The [LIGHT OUTPUT]
setting is synchronized with the [PROJECTOR SETUP] menu → [OPERATION SETTING] → [LIGHT OUTPUT].
The most recent setting is reflected in both items.
1)
Press as to select [LIGHT OUTPUT].
2)
Press qw to adjust.
Operation
Press w.
Press q.
Note
f [LIGHT OUTPUT] can be adjusted individually for each setting item of [OPERATING MODE].
f In such a case when configuring multiple screens with multiple projectors, uniformity of brightness between multiple screens can be
obtained by adjusting [LIGHT OUTPUT].
