REGULATORY APPROVAL
The user ’s manual should include the following
statement:
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.
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
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.

MRF24J40MB SETTINGS
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
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).
finished product without obtaining subsequent and
separate FCC approvals.
3.1.2
RF EXPOSURE
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:
Contains Transmitter Module FCC ID:
OA3MRF24J40MB
-or-
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.
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.
