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.
