4.0 REGULATORY APPROVAL
This section outlines the regulatory information for the
MRF24WN0MA/MB module for the following countries:
• United States
• Canada
• Europe
• Australia
• New Zealand
• Japan
• Korea
• Taiwan
• Other Regulatory Jurisdictions
4.1 United States
The MRF24WN0MA/MB module has received Federal
Communications Commission (FCC) CFR47 Telecom-
munications, Part 15 Subpart C “Intentional Radiators”
modular approval in accordance with Part 15.212 Mod-
ular Transmitter approval. Modular approval allows the
end user to integrate the MRF24WN0MA/MB module
into a finished product without obtaining subsequent
and separate FCC approvals for intentional radiation,
provided no changes or modifications are made to the
module circuitry. Changes or modifications could void
the user’s authority to operate the equipment. The end
user must comply with all of the instructions provided
by the Grantee, which indicate installation and/or oper-
ating conditions necessary for compliance.
The finished product is required to comply with all appli-
cable FCC equipment authorizations regulations,
requirements and equipment functions not associated
with the transmitter module portion. For example, com-
pliance must be demonstrated to regulations for other
transmitter components within the host product; to
requirements for unintentional radiators (Part 15 Sub-
part B “Unintentional Radiators”), such as digital
devices, computer peripherals, radio receivers, etc.;
and to additional authorization requirements for the
non-transmitter functions on the transmitter module
(i.e., Verification, or Declaration of Conformity) (e.g.,
transmitter modules may also contain digital logic func-
tions) as appropriate.

4.1.1
LABELING AND USER
INFORMATION REQUIREMENTS
The MRF24WN0MA/MB module has been labeled with
its own FCC ID number, and if the FCC ID is not visible
when the module is installed inside another device,
then the outside of the finished product into which the
module is installed must also display a label referring to
the enclosed module. This exterior label can use word-
ing as follows:
MRF24WN0MA/MB:
Contains Transmitter Module FCC ID: W7O24WN0
or
Contains FCC ID: W7O24WN0
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference,
and (2) this device must accept any interference
received, including interference that may cause
undesired operation
A user’s manual for the product should include the fol-
lowing statement:
This equipment has been tested and found to comply
with the limits for a Class B digital device, pursuant to
part 15 of the FCC Rules. These limits are designed
to provide reasonable protection against harmful
interference in a residential installation. This equip-
ment generates, uses and can radiate radio fre-
quency energy, and if not installed and used in
accordance with the instructions, may cause harmful
interference to radio communications. However,
there is no guarantee that interference will not occur
in a particular installation. If this equipment does
cause harmful interference to radio or television
reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to
correct the interference by one or more of the follow-
ing measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment
and receiver.
• Connect the equipment into an outlet on a circuit
different from that to which the receiver is con-
nected.
• Consult the dealer or an experienced radio/TV
technician for help.
