RF Energy Exposure Awareness and Control Information, and
Operational Instructions for FCC Occupational Use Requirements
NOTICE: This radio is intended for use in occupational/controlled conditions,
where users have full knowledge of their exposure and can exercise control over
their exposure to meet FCC limits. This radio device is NOT authorized for general
population, consumer, or any other use.
This 2-way radio uses electromagnetic energy in the radio frequency (RF) spectrum to
provide communications between two or more users over a distance. It uses RF energy
or radio waves to send and receive calls. RF energy is one form of electromagnetic
energy. Other forms include, but are not limited to, sunlight and x-rays. RF energy,
however, should not be confused with these other forms of electromagnetic energy,
which when used improperly, can cause biological damage. Very high levels of x-rays,
for example, can damage tissues and genetic material.
Experts in science, engineering, medicine, health, and industry work with organizations
to develop standards for safe exposure to RF energy. These standards provide
recommended levels of RF exposure for both workers and the general public. These
recommended RF exposure levels include substantial margins of protection.
All 2-way radios marketed in North America are designed, manufactured, and tested to
ensure they meet government-established RF exposure levels. In addition,
manufacturers also recommend specific operating instructions to users of 2-way radios.
These instructions are important because they inform users about RF energy exposure
and provide simple procedures on how to control it. Please refer to the following Web
sites for more information on what RF energy exposure is and how to control your
exposure to assure compliance with established RF exposure limits.

MCC RF Energy Exposure Guide 1 2/14/2007
Federal Communication Commission Regulations
The FCC rules require manufacturers to comply with the FCC RF energy exposure
limits for mobile 2-way radios before they can be marketed in the U.S. When 2-way
radios are used as a consequence of employment, the FCC requires users to be fully
aware of and able to control their exposure to meet occupational requirements.
Exposure awareness can be facilitated by the use of a label directing users to specific
user awareness information. Your MeteorComm (MCC) 2-way radio has an RF
exposure product label. Also, your MCC user manual, as well as this RF Energy
Exposure Guide guide, includes information and operating instructions required to
control your RF exposure and to satisfy compliance requirements.
Compliance with RF Exposure Standard
Your MCC two-way radio is designed and tested to comply with a number of national
and international standards and guidelines (listed below) regarding human exposure to
radio frequency electromagnetic energy. This radio complies with the IEEE and ICNIRP
exposure limits for occupational/controlled RF exposure environment at duty factors of
up to 50% talk-50% listen and is authorized by the FCC for occupational use. In terms
of measuring RF energy for compliance with the FCC exposure guidelines, your radio
antenna radiates measurable RF energy only while it is transmitting (during talking), not
when it is receiving (listening) or in standby mode.
Your MCC two-way radio complies with the following RF energy exposure
standards and guidelines:
• United States Federal Communications Commission, Code of Federal Regulations;
47CFR part 2 sub-part J
• American National Standards Institute (ANSI) / Institute of Electrical and Electronic
Engineers (IEEE) C95. 1-1992
• Institute of Electrical and Electronic Engineers (IEEE) C95.1-1999 Edition

RF Exposure Compliance and Control Guidelines
and Operating Instructions for Vehicular Installations
To control exposure to yourself and others and to ensure compliance with
occupational/controlled environment exposure limits, always adhere to the following
procedures.
1. Guidelines:
• These user awareness instructions should accompany the device or vehicle that
it is installed in when transferred to other users.
• Do not use this device if the operational requirements described herein are not
met.
2. Operator Instructions:
• For voice operation, transmit no more than the rated duty factor of 50% of
the time. To transmit (talk), push the Push-To-Talk (PTT) button. To receive
calls, release the PTT button. Transmitting 50% of the time, or less, is important
because this radio generates measurable RF energy exposure only when
transmitting (in terms of measuring for standards compliance).
• Be aware that a transmitter may operate automatically at any time when
functioning as a data radio. People outside of the vehicle must maintain the
recommended minimum lateral distance from the antennas at all times. It is the
responsibility of the vehicle’s operator to keep bystanders beyond the minimum
lateral distance from the antennas in order to comply with the FCC RF exposure
limits for an uncontrolled/general population environment.
• Transmit only when people outside the vehicle are at least the
recommended minimum lateral distance away, as shown in Table 1, from a
properly installed externally-mounted antenna.
NOTE: Table 1 below lists the recommended lateral distances to be maintained
between bystanders and approved, properly installed transmitting antennas (e.g.,
monopoles over a ground plane, or dipoles) in an uncontrolled environment for each of
the radio frequency bands available in MCC multi-band transceivers.

2412-2462 0.033 100% 8 in (20 cm)
NOTE: You, as the vehicle operator, should be knowledgeable of the location of
each of the antennas on the vehicle and of the minimum lateral distances applicable
to each. If this information is not available to you, contact your installer to obtain this
information. Until this information is available to you, keep bystanders at a distance
beyond the largest lateral distance specified in Table 1 (45 in.) from every antenna on
the vehicle.

Mobile Antenna Installation Guidelines
The following instructions apply only to vehicles with metal bodies or suitable ground
plane.
• Mount each antenna connected to a transmitter in the center of the roof or trunk
lid of the vehicle. When mounting an antenna to a trunk lid, be sure the minimum
lateral separation distances (Table 1) are maintained with respect to back seat
passengers.
• Install all antennas in accordance with the manufacturer’s instructions.
• Always disable the transmitter when installing or servicing an antenna or
transmission line or when working near an installed antenna.
• Mobile antennas may be installed at the center of a vehicle roof or trunk lid as
long as the minimum lateral distance is observed.
• Use only MCC-approved or MCC-supplied antennas. Unauthorized antennas,
modifications or attachments could damage the radio and their use may violate
FCC regulations.
RF Exposure Compliance, Control Guidelines and
Operating Instructions for Fixed Installations
To control exposure to yourself and others and to ensure compliance with RF exposure
limits, always adhere to the following procedures.
• Base station antennas should be installed on permanent outdoor structures, such
as the roof of a building or an antenna tower.
• Install all antennas in accordance with the manufacturer’s instructions.
• Always disable the transmitter when installing or servicing an antenna or
transmission line or when working near an installed antenna.
• Use only MCC-approved or MCC-supplied antennas. Unauthorized antennas,
modifications or attachments could damage the radio and their use may violate
FCC regulations.
• RF Exposure compliance at such sites must be addressed on a site-by-site
basis. It is the responsibility of the licensee to ensure compliance is met.
Approved Accessories
• This radio has been tested and meets the FCC RF exposure guidelines when
used with the MCC accessories supplied with or designated for the product. Use
of other accessories may not ensure compliance with the FCC’s RF exposure
guidelines, and may violate FCC regulations.
• For a list of MCC-approved accessories, refer to the operator manual, or contact
MCC.
