Electromagnetic Compatibility Tables
ZeroWire has been tested in an OR environment and the product did not interfere with electrosurgical,
ultrasound, X-Ray, medical displays and life monitoring equipment. Neither did the aforementioned equipment
interfere with ZeroWire. Additionally, since ZeroWire operates in 57 – 64 GHz, typically wireless LAN and mobile
phones will not cause interference as they operate outside the ZeroWire frequency range. However, the presence
of a source of interference within ZeroWire frequency range may result in intermittent operation and reduced
image quality or the link could go down while the interference exists. Prior to any procedure in the OR, it is
required that any such equipment be turned off and verify that the system operates as expected. If any
anomalous behavior is observed, it must be corrected prior to using the system in any surgical procedures.
ZeroWire transmitters should be separated by at least 20 inches (0.5 m). ZeroWire transmitters (Transmitter) or
receivers (Receiver) should not be installed in metal cabinets or surrounded by metallic objects, as this will
prevent the Transmitter from communicating with the Receiver.
During installation the ZeroWire link video quality should be tested with the Transmitter and Receiver at different
orientation angles, acceptable orientation angles are shown on page 10. Non-line-of-sight operation is discussed
under “Performance” on page 27. We recommend that the system be thoroughly tested prior to using it in any
surgical procedures.
Do not use power supplies or cable accessories with the ZeroWire other than those specified in this manual.
Excessive leakage currents, elevated electromagnetic emissions, or insufficient interference immunity may occur.
All medical electronic devices, including ZeroWire, must conform to the requirements of IEC 60601-1-2.
Precautions, adherences to the Electromagnetic Compatibility (EMC) guideline information provided in this
manual and verification of all medical devices in simultaneous operation are required to ensure the
electromagnetic compatibility and co-existence of all other medical devices prior to a surgical procedure.
