9. INFRARED SERVICE AREAS
9.1. Infrared Transmitter/Receiver
Notes
• Infrared signals cannot reach the Infrared Transmitter/Receiver unit if it is hidden behind the user or other
objects. Install multiple Transmitter/Receiver units in line-of-sight from all Chairman and Delegate units.
• Install the Infrared Transmitter/Receiver units in such a way that each Chairman and Delegate unit can
always communicate with two or more Transmitter/Receiver units. If installed in such a way that
communication is only established with one Transmitter/Receiver unit, the infrared signal may be blocked by
persons or other objects, possibly causing a momentary loss of signal reception.
