How does the Whitley Workstation wireless footswitch work?
OPERATION OF WHITLEY WORKSTATION FOOTSWITCH TRANSMITTERS The porthole door system on the Whitley range of workstations operates through an advanced wireless control technology. In specifying a radio control system suitable for use in hospitals and similar establishments it was important for us to choose a system not susceptible to external interference. Our system uses similar principles to those in car and domestic security alarms. If the receiver detects a transmitted signal that it does not recognise (even, for example, transmitted from another footswitch operating on a different channel) at the same time as a legitimate signal is detected, it will not perform the task as instructed. This is a safety feature. The implication is that two or more workstations installed near one another cannot have the porthole sequences performed at exactly the same time as each other. When we explain to customers the thinking and reasoning behind this safety feature they see the wisdom of how the sys
