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:

A user’s manual for the product should include the fol-

lowing statement:

Additional information on labeling and user information

requirements for Part 15 devices can be found in KDB

Publication 784748 available at the FCC Office of Engi-

neering and Technology (OET) Laboratory Division

MRF24WN0MA/MB:

Contains Transmitter Module FCC ID: W7O24WN0

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

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.
