MRF24J40MC
3.1.1
To meet the FCC requirements, the following settings
must be observed by the integrator:
• The MRF24J40MC transmit power setting shall
• Only channels 11 through 25 may be selected
3.1.2
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 manufacturer
provided the same antenna type, antenna gain (equal
to or less than), and MRF24J40MC power setting is
used for the same antenna type tested.
Testing of the MRF24J40MC module was performed
with the antenna types listed in
3.1.3
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 RF fields adopted by
the Federal Communications Commission (FCC). The

for
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.
The following statement must be included as a
CAUTION statement in manuals and OEM products to
alert users of FCC RF Exposure compliance:
If the MRF24J40MC module is used in a portable
application (antenna is less than 20 cm from persons
during operation), the integrator is responsible for
performing Specific Absorption Rate (SAR) testing in
accordance with FCC rules 2.1091.
3.1.4
Federal
http://www.fcc.gov
To satisfy FCC RF Exposure requirements for mobile
and base station transmission devices, a separation
distance of 20 cm or more should be maintained
between the antenna of this device and persons
during operation. To ensure compliance, operation at
closer than this distance is not recommended.
The antenna(s) used for this transmitter must not be
co-located or operating in conjunction with any other
antenna or transmitter.
