3.1.2 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 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.
3.1.3
APPROVED EXTERNAL ANTENNA
TYPES
To maintain modular approval in the United States, only
tested antenna types must be used. It is permissible to
use different manufacturer antenna provided the same
antenna type and antenna gain (equal to or less than)
is used.
MRF24WB0MB module testing was performed with the
antenna types listed in Table 2-2 in Section 2.8, Exter-
nal Antenna.

3.2 Canada
The MRF24WB0MA/MRF24WB0MB module is certi-
fied for use in Canada under Industry Canada (IC)
Radio Standards Specification (RSS) RSS-210 and
RSSGen. Modular approval permits the installation of a
module in a host device without the need to recertify
the device.
3.2.1
LABELING AND USER
INFORMATION REQUIREMENTS
Labeling requirements for the Host Device (from Sec-
tion 3.2.1, RSS-Gen, Issue 3, December 2010): The
host device must be labeled to identify the module
within the host device.
The Industry Canada certification label of a module
must 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 transmit-
ter module”, or the word “Contains”, or similar wording
expressing the same meaning, as follows:
Contains transmitter module IC:
8248A-G21ZEROG
User Manual Notice for License-Exempt Radio Appara-
tus (from Section 7.1.3, RSS-Gen, Issue 3, December
2010): User manuals for license-exempt radio apparatus
must contain the following or equivalent notice in a con-
spicuous 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 radioélec-
trique subi, même si le brouillage est susceptible
d'en compromettre le fonctionnement.
