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) Laboratory Division

8.1.2
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 8.0 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.
8.1.3
Approved External Antennas
To maintain modular approval in the United States, only the antenna types that have been tested shall be used. It
is permissible to use different antenna, provided they are of the same antenna type, antenna gain (equal to or less
than), similar in band and out-of band characteristics (consult specification sheet for cutoff frequencies).
Testing of the ATWILC3000-MR110UA module was performed with the antenna types listed in the table
.
8.1.4
Module Integration in the Host Product
Host products are to ensure continued compliance as per
KDB 996369 Module Integration Guide
8.2
Canada
The ATSAMA5D27-WLSOM1 module contains the ATWILC3000-MR110UA which has been certified for use in
Canada under Innovation, Science, and Economic Development (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.
8.2.1
Labeling and User Information Requirements
Labeling Requirements (from RSP-100 - Issue 11, Section 3): The host product 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 display the Innovation,
Science and Economic Development Canada certification number of the module, preceded by the word “Contains” or
similar wording expressing the same meaning, as follows:
Contains IC: 20266-WILC3000UA
