Electromagnetic Compatibility - NDS ZERO WIRE DUO Manual De Instrucciones

Electromagnetic Compatibility

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 0.5 meters (20 inches). 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 transmitter at different
orientation angles and mounting locations. This is required if the placement of the ZeroWire components
deviates from the recommended guidelines on page 9 of this manual or when they must be adjacent to or
stacked below other equipment. 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-
2:2001. 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 pages 17 and 18 are provided for your reference.
