Remote Control Operating Range
The remote control uses infrared transm ission 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. 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 li m-
ited in use. The following illustration shows the corresponding buttons on the remote control and on
the projector.
Some buttons on the projector have two functions. For example, item 5 on the projector functions
both as the volume down button and also as the left cursor key in OSD menus.
