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.

Note
f Under inuence of characteristics of each light source, conditions of use, installation environment, etc., the runtime may be shorter than the
estimation.
f If the consolidated runtime of the projector exceeds 20 000 hours, replacement of the components inside the projector may be required. The
consolidated runtime can be conrmed in the [STATUS] screen. Refer to the [PROJECTOR SETUP] menu → [STATUS] for details.
