RF Energy Exposure Awareness and Control Information and
Operational Instructions for Occupational Use
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 the occupational limits in FCC and International standards. This radio
device is NOT authorized for general population or consumer use.
-
iii
This two-way radio uses electromagnetic energy in the radio frequency (RF) spectrum to provide
communications between two or more users over a distance. It uses radio frequency (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 Motorola two-way radios 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 two-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 websites for more information on what RF energy exposure is and how
to control your exposure to assure compliance with established RF exposure limits:
http://www.fcc.gov/oet/rfsafety/rf-faqs.html
http://www.osha.gov/SLTC/radiofrequencyradiation/index.html
Federal Communication Commission (FCC) Regulations
The FCC rules require manufacturers to comply with the FCC RF energy exposure limits for portable
two-way radios before they can be marketed in the U.S. When two-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.
iv
Exposure awareness can be facilitated by the use of a product label directing users to specific user
awareness information. Your Motorola two-way radio has a RF exposure product label. Also, your
Motorola user manual, or separate safety booklet includes information and operating instructions
required to control your RF exposure and to satisfy compliance requirements.
Compliance with RF Exposure Standards
Your Motorola two-way radio is designed and tested to comply with a number of national and
International standards and guidelines (listed below) for human exposure to radio frequency
electromagnetic energy. This radio complies with the IEEE (FCC) and ICNIRP exposure limits for
occupational/controlled RF exposure environments at operating duty factors of up to 50% talk-50%
listen and is authorized by the FCC for occupational use only.
In terms of measuring RF energy for compliance with these exposure guidelines, your radio
generates measurable RF energy only while it is transmitting (during talking), not when it is receiving
(listening) or in standby mode.
NOTE:The approved batteries, supplied with this radio, are rated for a 5-5-90 duty factor (5% talk-
5% listen-90% standby) even though this radio complies with FCC occupational exposure
limits and may operate at duty factors of up to 50% talk.
Your Motorola 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
• International Commission on Non-Ionizing Radiation Protection (ICNIRP) 1998
• Ministry of Health (Canada) Safety Code 6. Limits of Human Exposure to Radiofrequency Electromagnetic Fields in the Frequency Range from 3 kHz to 300 GHz, 1999
• Australian Communications Authority Radiocommunications (Electromagnetic Radiation Human Exposure) Standard, 2003
• ANATEL ANNEX to Resolution No. 303 of July 2, 2002 "Regulation of limitation of exposure to
electrical, magnetic and electromagnetic fields in the radio frequency range between 9 KHz and
300 GHz" and "Attachment to resolution # 303 from July 2, 2002"
"Additional Requirements for SMR, Cellular and PCS Product Certification"
RF Exposure Compliance and Control Guidelines and Operating
Instructions
To control your exposure and ensure compliance with the occupational/controlled environment
exposure limits, always adhere to the following procedures.
Guidelines:
• Do not remove the RF Exposure Label from the device.
• User awareness instructions should accompany device when transferred to other users.
• Do not use this device if the operational requirements described herein are not met.
Operating Instructions
• Transmit no more than the rated duty factor of 50% of the time. To transmit (talk), push the PushTo-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).
• Hold the radio in a vertical position in front of the face with the microphone (and
other parts of the radio including the antenna) at least one inch (2.5 centimeters)
away from the nose or lips.
• Antenna should be kept away from the eye. Keeping the radio at a proper distance
is important since RF exposures decrease with increasing distance from the
antenna.
• When worn on the body, always place the radio in a Motorola-approved clip, holder, holster,
case, or body harness for this product. Using approved body-worn accessories is important
because the use of non-Motorola-approved accessories may result in exposure levels, which
exceed the FCC occupational/controlled environment RF exposure limits.
• If you are not using a body-worn accessory and are not using the radio in the intended use position in front of the face, ensure the antenna and the radio are kept at least one inch (2.5 centimeters) from the body when transmitting. Keeping the radio at a proper distance is important
because RF exposures decrease with increasing distance from the antenna.
Approved Accessories
• Use only Motorola-approved supplied or replacement antennas, batteries, and accessories. Use
of Non-Motorola approved antennas, batteries, and accessories may exceed the FCC (IEEE)
and ICNIRP RF exposure guidelines.
• For a list of Motorola-approved accessories, visit the following website, which lists approved
accessories for your radio model: http://www.motorola.com/governmentandenterprise

Electromagnetic Interference/Compatibility
NOTE:Nearly every electronic device is susceptible to electromagnetic interference (EMI) if
inadequately shielded, designed, or otherwise configured for electromagnetic compatibility.
Facilities
To avoid electromagnetic interference and/or compatibility conflicts, turn off your radio in any facility
where posted notices instruct you to do so. Hospitals or health care facilities may be using
equipment that is sensitive to external RF energy.
Aircraft
When instructed to do so, turn off your radio when on board an aircraft. Any use of a radio must be
in accordance with applicable regulations per airline crew instructions.
Medical Devices
Pacemakers
The Advanced Medical Technology Association (AdvaMed) recommends that a minimum separation
of 6 inches (15 centimeters) be maintained between a handheld wireless radio and a pacemaker.
These recommendations are consistent with those of the U.S. Food and Drug Administration.
vi
Persons with pacemakers should:
• ALWAYS keep the radio more than 6 inches (15 centimeters) from their pacemaker when the
radio is turned ON.
• Not carry the radio in the breast pocket.
• Use the ear opposite the pacemaker to minimize the potential for interference.
• Turn the radio OFF immediately if there is any reason to suspect that interference is taking place.
Hearing Aids
Some digital wireless radios may interfere with some hearing aids. In the event of such interference,
you may want to consult your hearing aid manufacturer to discuss alternatives.
Other Medical Devices
If you use any other personal medical device, consult the manufacturer of your device to determine
if it is adequately shielded from RF energy. Your physician may be able to assist you in obtaining this
information.
Use of communication devices while driving
Always check the laws and regulations on the use of radios in the areas where you drive.
• Give full attention to driving and to the road.
• Use hands-free operation, if available.
• Pull off the road and park before making or answering a call, if driving conditions or regulations
so require.
Operational Warnings
For vehicle with air bags
Refer to vehicle manufacturer's manual prior to installation of electronic equipment to avoid
interference with air bag wiring.
Do not place a portable radio in the area over an air bag or in the air bag deployment area.
Air bags inflate with great force. If a portable radio is placed in the air bag deployment area
and the air bag inflates, the radio may be propelled with great force and cause serious injury
to occupants of the vehicle.
Potentially Explosive Atmospheres
(Explosive atmospheres refers to hazard classified locations that may contain hazardous
gas, vapors, or dusts.)
Turn off your radio prior to entering any area with a potentially explosive atmosphere unless
it is a portable radio type especially qualified for use in such areas as Intrinsically Safe (for
example, Factory Mutual, CSA, UL, or CENELEC).
Do not remove, install, or charge batteries in such areas. Sparks in a potentially explosive
atmosphere can cause an explosion or fire resulting in bodily injury or even death.
The areas with potentially explosive atmospheres referred to above include fueling areas
such as below decks on boats, fuel or chemical transfer or storage facilities, and areas
where the air contains chemicals or particles such as grain, dust or metal powders. Areas
with potentially explosive atmospheres are often, but not always, posted.
Blasting Caps And Blasting Areas
To avoid possible interference with blasting operations, turn off your radio when you are
near electrical blasting caps, in a blasting area, or in areas posted: "Turn off two-way radio."
Obey all signs and instructions.
Operational Cautions
Antennas
Do not use any portable radio that has a damaged antenna. If a damaged antenna comes into contact
with your skin, a minor burn can result.
Batteries
All batteries can cause property damage and/or bodily injury, such as burns, if a conductive material
such as jewelry, keys, or beaded chains touches exposed terminals. The conductive material may
complete an electrical circuit (short circuit) and become quite hot. Exercise care in handling any
charged battery, particularly when placing it inside a pocket, purse, or other container with metal
objects.
Intrinsically Safe Radio Information
The Intrinsically safe approval unit refers to a product that has been approved as intrinsically safe by
an approval agency (for example FM Approvals, CSA, UL, or Cenelec) and certifies that a particular
product meets the Agency's applicable intrinsic safety standards for specific types of hazardous
classified locations. A portable radio that has been approved for intrinsic safety will have Approval
label attached to the radio to identify the unit as being Approved for specified hazardous
atmospheres. This label specifies the hazardous Class/Division/Group along with the part number of
the battery that must be used. The intrinsically safe approval label will be located on the portable
radio unit.
vii
Operational Cautions for Intrinsic Safe Equipment
• Do not operate radio communications equipment in a hazardous atmosphere unless it is a type
especially qualified (for example, FM, UL, CSA, or CENELEC approved). An explosion or fire may
result.
• Do not operate a radio unit that has been approved as intrinsically safe product in a hazardous
atmosphere if it has been physically damaged (for example, cracked housing). An explosion or fire
may result.
• Do not replace or charge batteries in a hazardous atmosphere. Contact sparking may occur while
installing or removing batteries and cause an explosion or fire.
Warnings for Radios Approved as Intrinsically Safe
Radios must ship from the Motorola manufacturing facility with the hazardous atmosphere capability
and the intrinsic safety approval labelling (FM, UL, CSA, CENELEC). Radios will not be upgraded to
this capability and labeled once they have been shipped to the field.
viii
Repair
A modification changes the unit's hardware from its original design configuration. Modifications can
only be made by the original product manufacturer.
• Do not replace or change accessories in a hazardous atmosphere. Contact sparking may
occur while installing or removing accessories and cause an explosion or fire.
• Turn the radio off before removing or installing a battery or accessory.
• Do not disassemble an intrinsically safe product in any way that exposes the internal
circuits of the unit.
• Failure to use an intrinsically safe approved battery or Approved accessories specifically
approved for the radio unit may result in the dangerously unsafe condition of an
unapproved radio combination being used in a hazardous location.
• Unauthorized or incorrect modification of the intrinsically safe approved Product will
negate the approval rating of the product.
• Incorrect repair or relabeling of any intrinsically safe Agency approved radio could
adversely affect the Approval rating of the unit.
• Use of a radio that is not intrinsically safe in a hazardous atmosphere could result in
serious injury or death.
REPAIRS FOR MOTOROLA PRODUCTS WITH INTRINSICALLY SAFE APPROVAL ARE THE
RESPONSIBILITY OF THE USER.
• Repairs to a Motorola FM approved radio product should only be done at a location that
has been FM audited under the FM 3605 repairs and service standard.
• Contact Motorola for assistance regarding repairs and service of Motorola intrinsically
safe equipment.
A repair constitutes something done internally to the unit that would bring it back to its original
condition.
Items not considered as repairs are those in which an action is performed on a unit which does not
require the outer casing of the unit to be opened in a manner that exposes the internal electrical
circuits of the unit.
Do Not Substitute Options or Accessories
The Motorola communications equipment certified as intrinsically safe by the approving agency,
(FM, UL, CSA, CENELEC) is tested as a complete system which consists of the listed agency
Approved portable, Approved battery, and Approved accessories or options, or both. This Approved
portable and battery combination must be strictly observed. There must be no substitution of items,
even if the substitute has been previously Approved with a different Motorola communications
equipment unit. Approved configurations are listed by the Approving Agency (FM, UL, CSA,
CENELEC).
The intrinsically safe Approval label affixed to radio refers to the intrinsically safe classification of
that radio product, and the approved batteries that can be used with that system.
The manual PN referenced on the intrinsically safe approval label identifies the approved
Accessories and or options that can be used with that portable radio unit.
Using a non Motorola intrinsically safe battery and or accessory with the Motorola approved radio
unit will void the intrinsically safe approval of that radio unit.
