REGULATORY APPROVAL

The MRF24J40MB module has received regulatory

approvals for modular devices in the United States,

Canada and European countries. Modular approval

allows the end user to place the MRF24J40MB module

inside a finished product and not require regulatory

testing for an intentional radiator (RF transmitter), pro-

vided 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

operating conditions necessary for compliance.

The integrator may still be responsible for testing the end

product for any additional compliance requirements

required with this module, installed (for example: digital

device emission, PC peripheral requirements, etc.) in

the specific country that the end device will be marketed.

Annex F of the IEEE Std. 802.15.4 document has a good

summary of regulatory requirements in various countries

concerning IEEE Std. 802.15.4 devices. The standard

can be downloaded from the IEEE Standards web page:

http://standards.ieee.org/getieee802/802.15.html.

Refer to the specific country radio regulations for

details on regulatory compliance.

3.1

United States

The

MRF24J40MB

has

received

Federal

Communications

Commission

(FCC)

CFR47

Telecommunications, Part 15 Subpart C “Intentional

Radiators” 15.247 and modular approval in accordance

with FCC Public Notice DA 00-1407 Released: June 26,

2000, Part 15 Unlicensed Modular Transmitter Approval.

The MRF24J40MB module can be integrated into a

finished product without obtaining subsequent and

separate FCC approvals.

The MRF24J40MB 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

wording such as the following:

The user’s manual should include the following

statement:

3.1.1

MRF24J40MB SETTINGS

To meet the FCC requirements, the following settings

must be observed by the integrator:

• The MRF24J40MB transmit power setting

(RFCON3 0x203) cannot exceed -1.9 dB.

• Only channels 11 through 25 may be selected

(RFCON0 0x200).

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.

Contains FCC ID: OA3MRF24J40MB

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

residential

installation.

This

equipment generates, uses and can radiate radio

frequency 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 following 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

connected.

• Consult the dealer or an experienced radio/TV

technician for help.
