Electromagnetic Compatibility (EMC ) Tables
ZeroWire has been tested in an OR environment and 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 3.1 – 4.8 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 (.5 m). ZeroWire transmitters (Tx) or
receivers (Rx) should not be installed in metal cabinets or surrounded by metallic objects, as this will
prevent the Tx from communicating with the Rx.
During installation the ZeroWire link video quality should be tested with the Tx and Rx at different
orientation angles, acceptable orientation angles are shown on page 12.
Non Line of Sight Operation
is
discussed on page 13. 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
7
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 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.
The EMC tables on the next three pages are provided for your reference.
