Projector PC 

Swap IR function for PC or Projector, the red Projector LED flashes when using 
the remote control in Projector mode; the green PC LED flashes when using the 
remote control in PC mode 

Note: 

The remote control can only interface with a computer for PC mouse function when connected to 
the computer through a USB cable connection. 

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.
