Remote Control Operating Range
The remote control uses infrared transmission to control the projector. It is not necessary to
point the remote directly at the projector. Provided you are not holding the remote
perpendicular to the sides or the rear of the projector, the remote will function well within a
radius of about 7 meters (23 feet) and 15 degrees above or below the projector level. If the
projector does not respond to the remote control, move a little closer.
Projector and Remote Control Buttons
The projector can be operated using the remote control or the buttons on the top of the
projector. All operations can be carried out with the remote control; however, the buttons on
the projector are limited in use.
