1.  Avoid using the projector with bright fluoresc ent lighting turned on. Certain high-frequency fluo-
rescent lights can disrupt remote control operation.

tween the 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 descri bes the functions based on the remote control.

Remote Control Operating Range 
The remote control uses infrared transmission to cont rol 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 re mote will function well within a radi us of about 7 meters (23 feet) and 
15 degrees above or below the projector level. If the pr ojector does not respond to the remote control, 
move a little closer.   
Projector and Remote Control Buttons 
The projector can be operated using t he remote control or the buttons on the top of the projector. All 
operations can be carried out with the remote cont rol; however, the buttons on the projector are lim-
ited in use.
