Relationship between brightness and runtime
The projector can be operated
w
ith arbitrary brightness and runti
m
e by setting [LIGHT OUTPUT] to desired
setting.
The relationship bet
w
een the [LIGHT OUTPUT] setting, brightness, and the esti
m
ated runti
m
e is as follo
w
s. Make
the initial setting
(
operation setting
)
depending on the desired brightness of the projected i
m
age and runti
m
e.
The
v
alues of the brightness and the runti
m
e are just an esti
m
ate, and the graph indicating the relationship is just
an exa
m
ple. Also, these do not indicate the
w
arranty period.
