Avoiding Co-Channel Interference
If the ZeroWire G2 deployment is a typical one-system per room, there are essentially no restrictions. The
transmitter’s Channel Selection feature picks the channel that is least susceptible to interference from the two
available channels based on the result of its scan at power on.
Some of the factors affecting isolation of the ZeroWire G2 channels are listed below:
1. The thickness and material of the room walls.
2. The opening and closing of room doors.
3. The room’s ceiling structure and the materials used in its construction.
ZeroWire G2 Transmitter/Receiver pairs must be installed in the same room. Cross room operation is not
supported. When two Transmitter/Receiver pairs are installed in a given room, each pair must be linked
separately, one pair at a time, linking the second pair after successfully linking the first. There is no need to
turn off the first linked pair before powering or linking the second pair.
Channel Usage
The recommendations listed below should be used to determine the appropriate setting:
1. ZeroWire G2 Transmitter and/or Receiver units cannot be used with earlier ZeroWire Transmitter and/or
Receiver units.
2. A maximum of two ZeroWire systems may be operated in the same room. The linked Transmitter and
Receiver pairs should be separated by at least 3 feet (1 m) within the room.
3. Groups of two ZeroWire systems may be set in multiple rooms, providing the rooms are spaced at least 25
feet (7.6 m) apart.
4. ZeroWire G2 Transmitters and Receivers should not be installed in metal cabinets or surrounded by metallic
objects, as this will prevent Transmitter communication with the Receiver.
Multi System Installation
When two paired Transmitter and Receiver systems are to be installed in a given OR, use the following procedure:
1. If the Transmitters and Receivers have not been linked, power up the first Transmitter and Receiver pair, and
follow the Linking Procedure described on page 30.
2. Power up the second Transmitter and Receiver pair, and repeat the Linking Procedure. Transmitter and
Receiver pairs must be linked one pair at a time. We recommend that linked pairs be labeled to facilitate
installation and troubleshooting.
Performance
ZeroWire HD Wireless Video System is intended and optimized for use in surgical or procedure rooms. Usage
outside of a clinical environment is not recommended.
The following steps will help you to achieve optimal performance of the ZeroWire system:
1. Mount both components at least 5 feet (1.5 m) from the floor.
2. Ideally, both the Transmitter and Receiver should be at the same height.
3. For a reliable video link, please follow the setup guidelines described on page 29.
4. The Transmitter and Receiver should be facing each other and be visible to each other in free air space.
5. For non-line-of-sight applications, we recommend that Transmitters and Receivers be located ≤ 6 feet (1.8 m)
or less from the walls.
