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.
