A clear line of sight between the microphone and the receiver is critical for best

performance. Take the following potential obstructions to the IR signal into consideration

when placing the receiver:

• Movable furniture (such as desks, tables, and podiums)

• Installed furniture (such as bookcases, racks, cabinets, workbenches, and sinks)

• Support pillars

• I-beams

• Projectors
