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 10 meters (33 feet) and 30 degrees above or below the projector level.
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. The following illustration shows the corresponding buttons on the
remote control and on the projector.
Remote Control
Some buttons on the projector have two functions. For example, item 9/11 on the projector
functions both as the keystone button and as the up arrow key in OSD menus.
