3.1.1
All transmitters regulated by FCC must comply with RF
exposure requirements. OET Bulletin 65, Evaluating
Compliance with FCC Guidelines for Human Exposure
to Radio Frequency Electromagnetic Fields, provides
assistance 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). The bulletin offers guidelines and
suggestions for evaluating compliance.
If appropriate, compliance with exposure guidelines for
mobile and unlicensed devices can be accomplished
by the use of warning labels and by providing users
with information concerning minimum separation dis-
tances from transmitting structures and proper
installation of antennas.
The following statement must be included as a
CAUTION statement in manuals and OEM products to
alert users of FCC RF exposure compliance:
If the MRF24WB0MA/MRF24WB0MB module is used
in a portable application (i.e., the antenna is less than
20 cm from persons during operation), the integrator is
responsible for performing Specific Absorption Rate
(SAR) testing in accordance with FCC rules 2.1091.
3.1.2
Federal Communications Commission (FCC): 
http://www.fcc.gov
DS70632A-page 22
To satisfy FCC RF Exposure requirements for
mobile and base station transmission devices, a
separation distance of 20 cm or more should be
maintained between the antenna of this device and
persons during operation. To ensure compliance,
operation at closer than this distance is not recom-
mended.
The antenna(s) used for this transmitter must not
be co-located or operating in conjunction with any
other antenna or transmitter.

The label is shown in the following example:
“Host devices which contain separately certified
modules do not need to be recertified, provided
that they meet the following conditions:
a) The host device, as a stand-alone unit without
b) The host device and all the separately certified
c) The host device complies with the certification
“All Category I radio equipment intended for use
in Canada shall permanently display on each
transmitter, receiver or inseparable combination
thereof, the applicant’s name (i.e., manufacturer’s
name, trade name or brand name), model num-
ber and certification number. This information
shall be affixed in such a manner as to not be
removable except by destruction or defacement.
The size of the lettering shall be legible without
the aid of magnification, but is not required to be
larger than 8-point font size. If the device is too
small to meet this condition, the information can
be included in the user manual upon agreement
with Industry Canada.”
NOTE: Compliance of a module in its final configu-
ration is the responsibility of the applicant. A host
device will not be considered certified if the instruc-
tions regarding antenna configuration provided in
the original description, of one or more separately
certified modules it contains, were not followed.
