P43596 E 5 EN DRAFT PPrroodduucctt DDeessccrriippttiioonn The SYNK 4K Wireless System wirelessly transfers video data from a transmitter to up to two linked receivers. The transmitter provides an HDMI input that supports 1080p and 4K video formats, and the receiver provides an HDMI output supporting the same formats. Once the devices are linked, the transmitter wirelessly transfers high-definition video to the receiver for output on a secondary display. At least one transmitter, one receiver, and a pairing token are required for full functionality of the system. A link between the transmitter and the receiver(s) is established by manually inserting a token in the transmitter and then in the receiver(s). Encrypted network data is written onto the token from the transmitter, and the data is decrypted in the receiver to establish a private and secure connection. A token is a small memory device that is programmed with frequencies allowed to establish a link. The receiver can optionally be mounted to the back of the 32 4K Surgical Display (0240031050), and it comes with the necessary mounting hardware. A dedicated power supply is included with the transmitter and the receiver to provide power. Alternatively, a Y-cable is provided with the receiver so it can share the 32 4K Surgical Displays power supply (use when the receiver is mounted to the back of that display). The system transfers video data without controlling or altering the functions or parameters of any connected devices. IInntteennddeedd UUssee The SYNK 4K Wireless System is intended for wireless transmission of high definition video data to secondary displays in a professional healthcare setting.

Each system uses a portion of the RF spectrum commonly referred to as a channel to broadcast its signal. The list of allowed channels is regulated and varies by region. The SYNK 4K Wireless System uses 40 MHz channels in the 5.170-5.850 GHz spectrum. The 5.170-5.850 GHz spectrum is also used by 802.11a/n/ac devices as well as 5.8 GHz cordless phones. The System uses an automatic frequency selection (AFS) mechanism in combination with a passive scanning capability to maintain compatibility with these devices and identify unoccupied channels for use. Each linked SYNK 4K Wireless System requires two 40 MHz channels to properly operate. The System is designed to transmit video on a single 40 MHz channel and allocate an additional 40 MHz channel as a backup in case of co-channel interference. Systems that are separated by a large distance may use the same channel. NNoottee -- The SYNK 4K Wireless System uses a proprietary transmission method, which cannot connect to or be accessed by 802.11 devices or 5.8 GHz cordless phones. In order to make sure that there are enough free channels for each SYNK 4K Wireless System, follow the steps outlined below:

1. Contact your IT administrator to determine if 802.11a or 802.11n WiFi is in use at your facility. If so, note which channels are in use in or near each SYNK 4K Wireless System installation location. 2. Determine if any 5.8 GHz cordless phones are in use at your facility. If so, note their locations. 3. For each SYNK 4K Wireless System installation location, ensure that there are two unused 40 MHz channels per SYNK 4K Transmitter installed. If a 5.8 GHz cordless phone is used in the vicinity, assume that channels 149-165 are occupied. Contact your Stryker sales representative for more details.

Once the devices are linked, the transmitter wirelessly transfers high-defi nition video to the receiver for output on a secondary display. At least one transmitter, one receiver, and a pairing token are required for full functionality of the system. A link between the transmitter and the receiver(s) is established by manually inserting a token in the transmitter and then in the receiver(s). Encrypted network data is written onto the token from the transmitter, and the data is decrypted in the receiver to establish a private and secure connection. A token is a small memory device that is programmed with frequencies allowed to establish a link. The receiver can optionally be mounted to the back of the 32 4K Surgical Display (0240031050), and it comes with the necessary mounting hardware. A dedicated power supply is included with the transmitter and the receiver to provide power. Alternatively, a Y-cable is provided with the receiver so it can share the 32 4K Surgical Displays power supply (use when the receiver is mounted to the back of that display). The system transfers video data without controlling or altering the functions or parameters of any connected devices. Intended Use The SYNK 4K Wireless System is intended for wireless transmission of high defi nition video data to secondary displays in a professional healthcare setting. The system is a non-sterile reusable device not intended for use in the sterile fi eld. Contraindications There are no contraindications for these devices. 4 DRAFT SYNK 4K Wireless Transmitter Package Contents

Each system uses a portion of the RF spectrum commonly referred to as a channel to broadcast its signal. The list of allowed channels is regulated and varies by region. The SYNK 4K Wireless System uses 40 MHz channels in the 5.170-5.850 GHz spectrum. The 5.170-5.850 GHz spectrum is also used by 802.11a/n/ac devices as well as 5.8 GHz cordless phones. The System uses an automatic frequency selection (AFS) mechanism in combination with a passive scanning capability to maintain compatibility with these devices and identify unoccupied channels for use. Each linked SYNK 4K Wireless System requires two 40 MHz channels to properly operate. The System is designed to transmit video on a single 40 MHz channel and allocate an additional 40 MHz channel as a backup in case of co-channel interference. Systems that are separated by a large distance may use the same channel. Note: The SYNK 4K Wireless System uses a proprietary transmission method, which cannot connect to or be accessed by 802.11 devices or 5.8 GHz cordless phones. In order to make sure that there are enough free channels for each SYNK 4K Wireless System, follow the steps outlined below:

1. Contact your IT administrator to determine if 802.11a or 802.11n WiFi is in use at your facility. If so, note which channels are in use in or near each SYNK 4K Wireless System installation location. 2. Determine if any 5.8 GHz cordless phones are in use at your facility. If so, note their locations. 3. For each SYNK 4K Wireless System installation location, ensure that there are two unused 40 MHz channels per SYNK 4K Transmitter installed. If a 5.8 GHz cordless phone is used in the vicinity, assume that channels 149-

165 are occupied. Contact your Stryker sales representative for more details. 16 DRAFT Operation Pairing is the act of creating a wireless link between a transmitter and a receiver. A token is used to create the link, by inserting it into the token slot of the transmitter to write discrete pairing data and then inserting the token into the token slot of the receiver to read the pairing data. A transmitter can pair with up to two (2) receivers. The same token may be used to create each pair, or a diff erent token may be used for each pair. Once paired, a transmitter can wirelessly transmit video data to a receiver, which can send the video data from its HDMI OUT port to a display. The transmitter can also wirelessly transmit data to a receiver, which can send the data from its remotes ports to a digital capture device. Pairing the Devices Using a Temporary Token (Blue) REF: 0105208884 To pair a transmitter with a receiver:

1. Power on the transmitter and receiver. The token LED remains off as the devices perform startup functions. 2. When the LED pulses white, insert the temporary token into the token slot on the transmitter. 3. When the token LED is green, remove the token from the transmitter. 4. Within 2 minutes and 30 seconds, insert the token into the token slot on 5. Remove the token from the token slot on the receiver when the token the receiver. LED fl ashes green.
