Safety Information
Product Safety and RF Energy Exposure for Portable Two-Way Radios
The information provided in this document supersedes the general safety information published 
prior to February 2002.
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. 
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. Exposure awareness can be facilitated by the use of a 
product label directing users to specific user awareness information. Your Motorola two-way radio 
BEFORE USING THIS RADIO, READ THE FOLLOWING INFORMATION WHICH CONTAINS 
IMPORTANT OPERATING INSTRUCTIONS FOR SAFE USAGE AND RF ENERGY AWARENESS 
AND CONTROL INFORMATION AND OPERATIONAL INSTRUCTIONS FOR COMPLIANCE WITH 
RF ENERGY EXPOSURE LIMITS IN APPLICABLE NATIONAL AND INTERNATIONAL 
STANDARDS. ALSO READ THE OPERATIONAL INSTRUCTIONS FOR SAFE USAGE. FOR 
RADIOS THAT HAVE BEEN APPROVED AS INTRINSICALLY SAFE, READ THE INSTRUCTIONS 
AND INFORMATION ON INTRISINIC SAFETY ON PAGE

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 Elec-
tromagnetic 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 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). 
						

							v
•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 posi-
tion in front of the face, ensure the antenna and the radio are kept at least one inch (2.5 centime-
ters) 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:

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.
Persons with pacemakers should:
• ALWAYS keep the radio more than 6 inches (15 centimeters) from their pacemaker when the 
radio is turned ON. 
						

							vi
• 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 manufacturers 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.
