4.1.2

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).
This module is approved for installation into mobile
and/or portable host platforms and must not be co-
located or operating in conjunction with any other
antenna or transmitter except in accordance with FCC
multitransmitter guidelines. End users must be pro-
vided with transmitter operating conditions for satisfy-
ing RF Exposure compliance.

4.1.3

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 manufacturers
provided the same antenna type that has similar inband
and out-of-band radiation patterns and antenna gain
(equal to or less than) is used.
Modular approval testing of the MRF24WN0MA/MB
module was performed with the antenna types listed in

Table 3-1

.

4.2

Canada

The MRF24WN0MA/MB module has been certified for
use in Canada under Industry Canada (IC) Radio Stan-
dards 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.

4.2.1

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: 

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:

Transmitter Antenna (from Section 7.1.2 RSS-Gen,
Issue 3, December 2010): User manuals for transmit-
ters shall display the following notice in a conspicuous
location:

The above notice may be affixed to the device instead
of displayed in the user manual.

4.2.2

RF EXPOSURE

All transmitters regulated by IC must comply with RF
exposure requirements listed in RSS-102 - Radio Fre-
quency (RF) Exposure Compliance of Radiocommuni-
cation Apparatus (All Frequency Bands). 

Contains transmitter module IC: 7693A-24WN0

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'Indus-
trie Canada applicables aux appareils radio exempts 
de licence. L'exploitation est autorisée aux deux con-
ditions 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.

Under Industry Canada regulations, this radio trans-
mitter may only operate using an antenna of a type 
and maximum (or lesser) gain approved for the trans-
mitter by Industry Canada. To reduce potential radio 
interference to other users, the antenna type and its 
gain should be so chosen that the equivalent isotrop-
ically radiated power (e.i.r.p.) is not more than that 
necessary for successful communication.

Conformément à la réglementation d'Industrie Can-
ada, le présent émetteur radio peut fonctionner avec 
une antenne d'un type et d'un gain maximal (ou 
inférieur) approuvé pour l'émetteur par Industrie Can-
ada. Dans le but de réduire les risques de brouillage 
radioélectrique à l'intention des autres utilisateurs, il 
faut choisir le type d'antenne et son gain de sorte 
que la puissance isotrope rayonnée équivalente 
(p.i.r.e.) ne dépasse pas l'intensité nécessaire à 
l'établissement d'une communication satisfaisante.
