Important: 1. Avoid using the projector with bright fluorescent lighting turned on. Certain high-frequency fluo-rescent lights can disrupt remote control operation.  2. Be sure nothing obstructs the path between the remote control and the projector. If the path be-tween remote control and the projector is obstructed, you can bounce the signal off certain reflective surfaces such as projector screens.  3. The buttons and keys on the projector have the same functions as the corresponding buttons on the remote control. This user’s manual describes the functions based on the remote control.

Note: The remote control can only interface with a computer when connected to the computer through a USB cable connection. The computer cable connects a computer to the projector for display pur-poses only. 
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. 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 lim-
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 3/6 on the projector functions 
both as the source button and as the left cursor key in OSD menus.
