44. eceived When an area is detected where there is bad reception or even no reception at all three main causes must be considered 3 6 4 Bad coverage The receiver cannot pick up infra red radiation of adequate strength This can be because the tested position is outside the footprint of the installed radiators or the radiation is blocked by obstacles such as a column an overhanging balcony or other large objects Check that you used the correct footprints for the system design that radiators with enough output power are installed and that a radiator is not accidentally switched to half power operation When the bad reception is caused by a blocked radiation path try to remove the blocking obstacle or add an extra radiator to cover the shaded area 3 6 5 Black spots The receiver picks up IR signals from two radiators which cancel out each other The multipath effect can be identified by the observation that the bad reception only occurs along a specific line and or when good reception returns when the receiver is rotated to another direction This can be confirmed by keeping the receiver in the position and direction with the bad reception and then either shading off the radiation from one 20 Manual 01 18 05675 Danish Interpretation Systems radiator with your hand or switching off one radiator If this improves the reception quality then the multipath effect is causing the problem Note that IR radiation that is reflected f
