RF exposure
If you are an integrating the XBee 3 into another product, you must include the following Caution
statement in OEMproduct manuals to alert users of FCC RF exposure compliance:
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 are not recommended. The antenna used for this transmitter must not be co-
located in conjunction with any other antenna or transmitter.
XBee 3 USB Adapter
The XBee 3 USB Adapter integrates an XBee 3 RF Module into its hardware. Due to output power
limitations it is exempt from SAR testing. It is approved as a portable application.
FCC publication 996369 related information
In Publication 996369 section D03, the FCC requires information concerning a module to be presented
by OEM manufacturers. This section assists in answering or fulfilling these requirements.
2.1 General
No requirements are associated with this section.
2.2 List of applicable FCC rules
This module conforms to FCC Part 15.247.
2.3 Summarize the specific operational use conditions
Certain approved antennas require attenuation for operation. For the XBee 3, see XBee 3 RF module.
For the Pro XBee 3, see XBee3-PRO RF module.
Host product user guides should include the antenna table if end customers are permitted to select
antennas.
2.4 Limited module procedures
Not applicable.
2.5 Trace antenna designs
While it is possible to build a trace antenna into the host PCB, this requires at least a Class II
permissive change to the FCC grant which includes significant extra testing and cost. If an embedded
trace or chip antenna is desired, simply select the XBee 3 module variant with the preferred antenna.
2.6 RF exposure considerations
For RF exposure considerations see RF exposure and FCC-approved antennas (2.4 GHz).
Host product manufacturers need to provide end-users a copy of the “RF Exposure” section of the
manual: RF exposure.
