Operating Range
The infrared signal operates by line-of-sight up to a distance
of approximately 22 feet (7m) and within a 60-degree angle of
the remote sensor. The projector will not function if there are
objects between the remote control and the remote sensor on
the projector or if strong light falls on the remote sensor. A
weak battery will also prevent the projector from operating prop-
erly.
