3.1.1 RF EXPOSURE
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
distances 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:
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
recommended.
The antenna(s) used for this transmitter must not
be co-located or operating in conjunction with any
other antenna or transmitter.
If the MRF24WG0MA/MB 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
APPROVED EXTERNAL ANTENNA
TYPES
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 manufacturer
provided the same antenna type and antenna gain
(equal to or less than) is used.
Testing of the MRF24WG0MB module was performed
with the antenna types listed in Table 2-2 in
Section 2.0 “Circuit Description”.

3.2 Canada
The MRF24WG0MA/MB module has been certified for
use in Canada under Industry Canada (IC) Radio
Standards Specification (RSS) RSS-210 and RSS-
Gen. Modular approval permits the installation of a
module in a host device without the need to recertify
the device.
Labeling Requirements for the Host Device (from
Section 3.2.1, RSS-Gen, Issue 3, December 2010):
The host device shall be properly labeled to identify the
module within the host device.
The Industry Canada certification label of a module
shall be clearly visible at all times when installed in the
host device, otherwise the host device must be labeled
to display the Industry Canada certification number of
the module, preceded by the words “Contains
transmitter module”, or the word “Contains”, or similar
wording expressing the same meaning, as follows:
Contains transmitter module IC: 7693A-24WG0MAMB
User Manual Notice for License-Exempt Radio
Apparatus (from Section 7.1.3 RSS-Gen, Issue 3,
December 2010):
User manuals for license-exempt radio apparatus shall
contain the following or equivalent notice in a
conspicuous location in the user manual or
alternatively on the device or both:
This device complies with Industry Canada
license-exempt RSS standard(s). Operation is
subject to the following two conditions: (1) this
device may not cause interference, and (2) this
device must accept any interference, including
interference that may cause undesired operation of
the device.
Le présent appareil est conforme aux CNR
d'Industrie Canada applicables aux appareils radio
exempts de licence. L'exploitation est autorisée
aux deux conditions suivantes: (1) l'appareil ne doit
pas produire de brouillage, et (2) l'utilisateur de
l'appareil doit accepter tout brouillage
radioélectrique subi, même si le brouillage est
susceptible d'en compromettre le fonctionnement.
