Setup Linking the Transmitter and Receiver Prior to placing the ZeroWire G2 system in service, the Transmitter and Receiver pair must be linked. Once a Transmitter and Receiver pair is linked, they remain linked until the Transmitter is explicitly linked to another Receiver or the Receiver is explicitly linked to another Transmitter. Note: If a linked pair is turned off they will automatically link to each other when they are turned on again. Linking Procedure: 1. Connect a DVI or SDI video source to the Transmitter unit and a display to the Receiver unit’s DVI output (See Figure 1). 2. Press and hold the “LINK” button (see Figure 2) on the Receiver unit until its linking LED begins flashing blue rapidly, then release. At this point, the user has 60 seconds to move to the other unit and press the LINK button on that device. 3. Next, press and hold the “LINK” button (see Figure 2 for location) on the Transmitter unit until its linking LED begins flashing blue rapidly, then release. 4. When the Transmitter and Receiver units identify each other and begin to link, both the Status LED and Link LED on both units will flash rapidly for several seconds. Once the link is established, each unit’s linking LED turns off. Note: ZeroWire G2 Transmitter and Receiver units are not compatible with earlier ZeroWire Transmitter and Receiver units.

Passing Video: With the linking completed, the status LEDs should turn blue and the source image should appear on the display. This completes the basic setup. Note: The Transmitter and Receiver are not limited to line-of-sight operation, i.e., the pair will operate reliably despite the presence of intervening obstacles. However, neither unit should be completely surrounded by metallic objects.

For mission critical applications, we strongly recommend that a replacement ZeroWire G2 Transmitter and Receiver pair, and DVI cable, be immediately available. Additionally, we recommend that a display that is hard wired to the video source be immediately available whenever a surgical procedure is in progress.

Performance Performance: ZeroWire G2 HD Wireless Video System is intended and optimized for use in surgical or procedure rooms. Use outside of a clinical environment is not recommended. The following steps will help you to achieve optimal performance of the ZeroWire G2 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 under Positioning and Orientation on pages 10 and 11. 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 the Transmitter and Receiver be located within 6 feet (1.8 m) or less from the walls.

9

Positioning and Orientation Due to the shape of the antenna’s signal field, both Transmitter and Receiver units should be installed so they are aligned vertically and horizontally within ±10°. Vertical Alignment: Vertical alignment should be within ±10° of vertical. Horizontal Alignment: Horizontal alignment should be within ±10° of horizontal. Positioning and Orientation is continued on the following page

Positioning and Orientation (continued) Elevation: The Transmitter and Receiver should be positioned at least 5 feet (1.5 m) above the floor, be at the same height, and, preferably, with the Transmitter and Receiver front edges parallel and facing each other. Separation: ZeroWire G2 operates correctly with a Transmitter and Receiver separation of up to 30 feet (9.1 m). However, in the case of most OR environments, best results are achieved with a Transmitter and Receiver separation distance of up to 8 feet (2.4 m).

Non Line of Sight Operation The ZeroWire G2 System can maintain a wireless link with partial obstructions. However, best performance is realized with a clear line-of-sight between units. In an OR environment, the ceiling mounted boom system and its spring arm junctions, along with surgical light heads, are large metal structures that can potentially block the wireless signals if they obstruct the line-of-sight between the Transmitter and Receiver (see illustration below). Preferably, surgical lights should be positioned out of the way or raised above the line-of-sight. If an object must obstruct the line-of-sight, the best option is to position it half way between the Transmitter and the Receiver. OR rooms whose walls and/or ceiling are constructed with metal sheets may reduce ZeroWire G2 performance. This condition possibly can be mitigated by moving the Transmitter and Receiver closer to each other, setting their line-of-sight to 0 degrees (see page 10), and ensuring that there are no obstructions between the Transmitter and the Receiver.

12

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 G2 systems may be operated in the same room. The transmitters and receivers should be separated by at least 3 feet (1 m) within the room. 3. Groups of two ZeroWire G2 systems may be set in multiple rooms, providing the rooms are spaced at least 25 feet (7.6 m) apart. 4. ZeroWire G2 Transmitter and/or Receiver should not be installed in metal cabinets or surrounded by metallic objects, as this will prevent the Transmitter from communicating with the Receiver.

Multi System Installation Multiple Systems: When two systems are to be installed in a given OR use the following procedure: 1. If the Transmitter and Receiver units have not been linked apply power to one Transmitter and one Receiver then follow the Linking Procedure described on page 8. 2. Turn second Transmitter and Receiver pair on 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.

Signal Strength and On Screen Diagnostic (OSD) Messages When a receiver is connected to a monitor, self-explanatory diagnostic messages are displayed in the lower left corner of the screen to inform the user of the receiver’s current status. The messages will be displayed for 15 seconds, with the exception of “Search for transmitter wireless signal failed” and “No wireless signal detected: ss=0 vm=NONE.” “Search for transmitter wireless signal failed” and “No wireless signal detected: ss=0 vm=NONE” will be displayed until remedial action is taken. When the “No wireless signal detected: ss=0 vm=NONE” message and/or the 1-bar graph are displayed on the screen, the wireless link is unreliable and requires immediate remedial action. The Signal Strength bar graph is displayed in the lower right corner of the receiver’s monitor for 60 seconds at power up. It is also displayed when the link is established following a link disconnect. When the link quality is poor or bad the bar graph is automatically displayed to alert the user that remedial action is required. The bar graph may be activated manually by a single touch of the receiver’s LINK button. Signal Strength bar graph is displayed here
