5) Press as to select [LIGHT OUTPUT].
6) Press qw to adjust.
f When the Fixed-focus Lens (Model No.: ET-D75LE90) is used, set [LIGHT OUTPUT] to 66.7 % or less
considering the focus quality. The luminance when [LIGHT OUTPUT] is set to 66.7 % is 20 000 lm
(approximate).
Operation
Press w.
Press q.
7) Press the <ENTER> button to proceed to the initial setting.
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 Under influence of characteristics of each light source, conditions of use, installation environment, etc., the runtime may be shorter than the
estimation.
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 the time until when the luminance decreases approximately by half, except when [OPERATING MODE] is set to
[HIGH].
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.
