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:
• Reorient or relocate the receiving antenna
• Increase the separation between the equipment and receiver
• Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected
• Consult the dealer or an experienced radio/TV technician for help
Additional information on labeling and user information requirements for Part 15 devices can be found in
KDB Publication 784748, which is available at the FCC Office of Engineering and Technology (OET)

16.1.2 RF Exposure
All transmitters regulated by FCC must comply with RF exposure requirements. KDB 447498 General RF
Exposure Guidance provides guidance in determining whether proposed or existing transmitting facilities,
operations or devices comply with limits for human exposure to Radio Frequency (RF) fields adopted by
the Federal Communications Commission (FCC).
From the FCC Grant: Output power listed is conducted. This transmitter is restricted for use with the
specific antenna(s) tested in this application for Certification.
The antenna(s) used with this transmitter must be installed to provide a separation distance of at least 6.5
cm from all persons and must not be co-located or operating in conjunction with any other antenna or
transmitter. Users and installers must be provided with antenna installation instructions and transmitter
operating conditions for satisfying RF exposure compliance.

16.2 Canada
The ATWINC3400-MR210CA module has been certified for use in Canada under Innovation, Science and
Economic Development Canada (ISED, formerly Industry Canada) Radio Standards Procedure (RSP)
RSP-100, Radio Standards Specification (RSS) RSS-Gen and RSS-247. Modular approval permits the
installation of a module in a host device without the need to recertify the device.
16.2.1 Labeling and User Information Requirements
Label Requirements (from RSP-100 Issue 11, Section 3): The host device shall be properly labeled to
identify the module within the host device.
The Innovation, Science and Economic Development Canada certification label of a module shall be
clearly visible at all times when installed in the host device; otherwise, the host product must be labeled to
ATWINC3400-MR210CA
