Chapter 3 Basic Operations — Switching on/off the projector
Relationship between brightness and runtime
When [OPERATING MODE] is set to [NORMAL], [USER1], [USER2], or [USER3], the projector can be operated
with arbitrary brightness and runtime by setting [LIGHT OUTPUT] to desired setting.
The relationship between the [LIGHT OUTPUT] setting, brightness, and the estimated runtime is as follows. Make
the initial setting (operation 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 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 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]
menu → [BRIGHTNESS CONTROL] → [BRIGHTNESS CONTROL SETUP] → [CONSTANT MODE] to [AUTO] or [PC]. Refer to the
[PROJECTOR SETUP] menu → [BRIGHTNESS CONTROL] for details.
