Interrelation of brightness and runtime
The projector can be operated at arbitrary brightness and duration of use by combining the settings of [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.

Under inuences of characteristics of each light source, conditions of use, installation environment, etc., the runtime may be shorter than the
estimation.

If the runtime exceeds 20 000 hours, replacement of the components inside the projector may be required. Consult your dealer for details.
