My remote control does not work. What should I do?

• The remote control has it's own on/off switch on the side of the remote marked R/C. Make sure the R/C switch is in the "ON" position. Test the batteries by pressing the illumination button on the remote control. If the remote buttons don't light up, replace the batteries. The lighting in the room or the angle you are pointing at may be affecting the infra-red signal from reaching the projector properly.
