2Use the card to block areas of the VCR where the receiver might be located. Turn the VCR on and off, while pointing the remote control at the card blocking the VCR. Be sure the remote control is close to the VCR to reduce reflections the receiver may pick up.
3Note the area where the VCR is unresponsive to the remote control. This region contains the receiver and can be marked by loosely taping the index card to the area.
Because the IR Blaster radiates an area approximately 40 degrees wide, it is not necessary to be precisely on target with the remote control. Offset the location of the IR Blaster transmitters from the VCR receiver to reduce interference with operation of the VCR remote control.
