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] and [LIGHT OUTPUT].
Interrelation of luminance and runtime is as follows. Make the initial setting (operation setting) 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
The estimated runtime is a time for the luminance to decrease to half.
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 confirmed in the
[STATUS]
screen. Refer to the [PROJECTOR SETUP] menu
→
[STATUS] for details.
f
After completed the initial setting, the wider the combination of luminance and runtime becomes by setting the [PROJECTOR SETUP]

[BRIGHTNESS CONTROL SETUP]
→
[CONSTANT MODE] to [AUTO] or [PC]. Refer to the
