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 dis-
tances from transmitting structures and proper installa-
tion of antennas.
The following statement must be included as a CAU-
TION 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 MRF24J40MD/ME 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
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 MRF24J40MD/ME module was per-
formed with the antenna types listed in Table 2-1
Tested External Antenna Types.

3.2 Canada
The MRF24J40MD/ME module has been certified 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 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 transmit-
ter module”, or the word “Contains”, or similar wording
expressing the same meaning, as follows:
Contains transmitter module IC: 7693A-24J40MDME
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 appara-
tus shall contain the following or equivalent notice in a
conspicuous location in the user manual or alterna-
tively 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.
