Note 16: Contains FCC ID: OUR-XBEEPRO. The enclosed device complies with Part 15 of the FCC
Rules. Operation is subject to the following two conditions: (i.) this device may not cause harmful
interference and (ii.) this device must accept any interference received, including interference that may
cause undesired operation.
Note 17: Canada: Contains Model XBee Radio, IC: 4214A-XBEEPRO
Caution! To satisfy FCC RF exposure requirements for mobile transmitting devices, a separation distance
of 20 cm or more should be maintained between the antenna of this device and persons during
device operation. To ensure compliance, operations at closer than this distance is not
recommended. The antenna used for this transmitter must not be co-located in conjunction with
any other antenna or transmitter.

Note 18: Self-Powered Hub refers to a USB hub with an external power supply. Self-powered hubs allow a
connected USB device to draw up to 500 mA. This device may not be used with bus-powered hubs due
to the power supply requirements.
Root Port Hubs reside in the PC USB Host Controller. The USB port(s) on your PC are root port hubs.
All externally powered root port hubs (desktop PC) provide up to 500 mA of current for a USB device.
Battery-powered root port hubs provide 100 mA or 500 mA, depending upon the manufacturer. A
laptop PC that is not connected to an external power adapter is an example of a battery-powered root
port hub.
