Chapter 3 Basic Operations — Switching on/off the projector
62 - ENGLISH
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], [LIGHT OUTPUT], and [CONSTANT MODE] in [BRIGHTNESS CONTROL SETUP].
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 inuence 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 If the runtime exceeds 20 000 hours, replacement of the components inside the projector may be required. Consult your dealer for details.
Initial setting (installation setting)
Set [FRONT/REAR] and [FLOOR/CEILING] in [PROJECTION METHOD] depending on the installation mode.
Refer to “Installation mode” (x page 35) for details.
After completed the initial setting, you can change the setting from the [PROJECTOR SETUP] menu →
[PROJECTION METHOD].
1) Press qw to switch the setting.
