[LIGHT OUTPUT] cannot be adjusted if [OPERATING MODE] is set to [LONG LIFE1], [LONG LIFE2] or [LONG LIFE3] and the [PROJECTOR
SETUP] menu → [BRIGHTNESS CONTROL] → [BRIGHTNESS CONTROL SETUP] → [CONSTANT MODE] is set to [AUTO] or [PC].
f
In such a case when conguring multiple screens with multiple projectors, uniformity of brightness between multiple screens can be obtained
by adjusting [LIGHT OUTPUT].
Relationship between brightness and runtime
The projector can be operated with arbitrary brightness and runtime by combining the settings of [MAX LIGHT
OUTPUT LEVEL], [LIGHT OUTPUT], and [CONSTANT MODE] in [BRIGHTNESS CONTROL SETUP].
The relationship between the [LIGHT OUTPUT] setting, brightness, and the estimated runtime is as follows. Make
the setting depending on the desired brightness of the projected image and runtime.
The values of the brightness and the runtime are just an estimate, and the graph indicating the relationship is just
an example. Also, these do not indicate the warranty period.
