1.4 Wireless Microphone
The wireless microphone is available and serves as another audio input to the
SwitchPoint Infinity 3 Control System audio subsystem. The microphone uses Ultra High
Frequency (UHF) to transmit to the receiver. UHF is a common frequency range which
television stations use to broadcast their signal. The wireless microphone has been
tested to meet medical EMC and safety standards. The Instructions for Use contains
language informing the users of these radio frequencies. The theoretical maximum range
of the microphone transmitter is 91.5m (300’). This range is greatly limited inside of a
hospital operating room, due to the general construction of hospitals. The users are
instructed to test all equipment with the wireless microphone system to ensure that no
interference exists prior to the use of Stryker SwitchPoint Infinity 3 Control System.
