FCC notices

IMPORTANT: XBee/XBee-PRO Zigbee RF Modules have been certified by the FCC for use with other
products without any further certification (as per FCC section 2.1091). Modifications not expressly
approved by Digi could void the user's authority to operate the equipment.
IMPORTANT: OEMs must test final product to comply with unintentional radiators (FCC section 15.107
& 15.109) before declaring compliance of their final product to Part 15 of the FCC Rules.
IMPORTANT: The RF module has been certified for remote and base radio applications. If the module
will be used for portable applications, the device must undergo SAR testing.
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures: Re-orient or relocate the receiving antenna,
Increase the separation between the equipment and receiver, Connect equipment and receiver to
outlets on different circuits, or Consult the dealer or an experienced radio/TV technician for help.

FCC-approved antennas (2.4 GHz)

The XBee/XBee-PRO Zigbee RF Module can be installed using antennas and cables constructed with
non-standard connectors (RPSMA, RPTNC, etc.) An adapter cable may be necessary to attach the
XBee connector to the antenna connector.
The modules are FCC approved for fixed base station and mobile applications for the channels
indicated in the tables below. If the antenna is mounted at least 25 cm (10 in) from nearby persons,
the application is considered a mobile application. Antennas not listed in the table must be tested to
comply with FCC Section 15.203 (Unique Antenna Connectors) and Section 15.247 (Emissions).
The antennas in the tables below have been approved for use with this module. Cable loss is required
when using gain antennas as shown in the tables.
Digi does not carry all of these antenna variants. Contact Digi Sales for available antennas.
1. If using the RF module in a portable application (for example, if the module is used in a hand-
held device and the antenna is less than 25 cm from the human body when the device is in
operation), The integrator is responsible for passing additional Specific Absorption Rate (SAR)
testing based on FCC rules 2.1091 and FCC Guidelines for Human Exposure to Radio Frequency
Electromagnetic Fields, OET Bulletin and Supplement C. The testing results will be submitted
to the FCC for approval prior to selling the integrated unit. The required SAR testing measures
emissions from the module and how they affect the person.
2. Zigbee firmware will be limited to 32% duty cycle on channel 26.
3. If you are using 802.15.4 firmware with up to a 66% duty cycle on this channel.
