1.2 RF ENERGY EXPOSURE AWARENESS AND CONTROL

INFORMATION FOR FCC OCCUPATIONAL USE REQUIREMENTS

Before using the mobile two-way radio, read this important RF energy awareness and control

information and operational instructions to ensure compliance with RF exposure guidelines.

NOTE

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 remain

below RF exposure limits. This radio is NOT authorized for general population,

consumer, or any other use.

CAUTION

Changes or modifications not expressly approved by M/A-COM, Inc. could void the

user's authority to operate the equipment.

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 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, electric power, 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 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 two-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

MM-007024-001

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

1.2.1 Federal Communications Commission Regulations

The M7200 two-way mobile radio is designed and tested to comply with the FCC RF energy exposure

limits for mobile two-way radios before it can be marketed in the United States. 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

label directing users to specific user awareness information. The radio has an RF exposure product label.

Also, this Installation Manual and the applicable Operator’s Manual include information and operating

instructions required to control your RF exposure and to satisfy compliance requirements.

1.3 COMPLIANCE WITH RF EXPOSURE STANDARDS

The M7200 two-way mobile radio is designed and tested to comply with a number of national and

international standards and guidelines regarding human exposure to RF electromagnetic energy. This

radio complies with the IEEE and ICNIRP exposure limits for occupational/controlled RF exposure

environment at duty-cycle times of up to 50% (50% transmit, 50% receive), and it is authorized by the

FCC for occupational use. In terms of measuring RF energy for compliance with the FCC exposure

guidelines, the radio’s antenna radiates measurable RF energy only while it is transmitting (talking), not

when it is receiving (listening) or in standby mode.

The M7200 mobile two-way radio complies with the following RF energy exposure standards and

guidelines:

•United States Federal Communications Commission (FCC), Code of Federal Regulations; 47 CFR

§ 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.

CAUTION

Table 1-1 lists the recommended minimum safe lateral distances for a controlled

environment and for unaware bystanders in an uncontrolled environment, from

transmitting antennas (i.e., monopoles over a ground plane, or dipoles) at rated radio

power for mobile radios installed in a vehicle. Transmit only when unaware bystanders

are at least the uncontrolled recommended minimum safe lateral distance away from

the transmitting antenna.

1.3.1 Mobile Antennas

The antenna(s) for the radio must be installed in accordance with section 7 in this manual. Refer to Table

1-1 above and/or Figure 7-1 for applicable antenna part numbers. Installation guidelines presented in

section 7 are limited to metal-body motor vehicles or vehicles with appropriate ground planes.

Use only the M/A-COM approved/supplied antenna(s) or an approved replacement antenna. Unauthorized

antennas, modifications, or attachments can cause the FCC RF exposure limits to be exceeded.

1.3.2 Approved Accessories

The radio has been tested and meets FCC RF guidelines when used with M/A-COM accessories supplied

or designated for use with it. Use of other accessories may not ensure compliance with the FCC’s RF

exposure guidelines, and may violate FCC regulations. For a list of approved accessories refer to section 4

in this manual (begins on page 14) and/or M/A-COM’s Products and Services Catalog.

1.3.3 Contact Information

For additional information on RF exposure and other information, contact M/A-COM using one of the

contact links listed in section 3.3 on page 13.

1.4 OCCUPATIONAL SAFETY GUIDELINES AND SAFETY TRAINING

INFORMATION

To ensure bodily exposure to RF electromagnetic energy is within the FCC allowable limits for

occupational use, always adhere to the following basic guidelines:

1. The push-to-talk button should only be depressed when intending to send a voice message.

2. The radio should only be used for necessary work-related communications.

3. The radio should only be used by authorized and trained personnel. It should never be operated by

children.

4. Do not attempt any unauthorized modification to the radio. Changes or modifications to the radio may

cause harmful interference and/or cause it to exceed FCC RF exposure limits. Only qualified

personnel should service the radio.

5. Always use M/A-COM authorized accessories (antennas, control heads, speakers/mics, etc.). Use of

unauthorized accessories can cause the FCC RF exposure compliance requirements to be exceeded.

The information listed above provides the user with information needed to make him or her aware of a RF

exposure, and what to do to assure that this radio operates within the FCC exposure limits of this radio.

MM-007024-001

1.5 COMMON HAZARDS

The operator of any mobile radio should be aware of certain hazards common to the operation of

vehicular radio transmissions. Possible hazards include but are not limited to:

1. Explosive Atmospheres

Just as it is dangerous to fuel a vehicle with its motor running, be sure to turn the radio OFF while fueling

the vehicle. If the radio is mounted in the trunk of the vehicle, DO NOT carry containers of fuel in the

trunk.

2. Interference To Vehicular Electronic Systems

Electronic fuel injection systems, electronic anti-skid braking systems, electronic cruise control systems,

etc., are typical of the types of electronic devices that can malfunction due to the lack of protection from

radio frequency (RF) energy present when transmitting. If the vehicle contains such equipment, consult

the dealer for the make of vehicle and enlist his aid in determining if such electronic circuits perform

normally when the radio is transmitting.

3. Electric Blasting Caps

To prevent accidental detonation of electric blasting caps, DO NOT use two-way radio within 1000 feet

(305 meters) of blasting operations. Always obey the “Turn Off Two-Way Radios” signs posted where

electric blasting caps are being used. (OSHA Standard: 1926.900)

4. Radio Frequency Energy

To prevent burns or related physical injury from radio frequency energy, do not operate the transmitter

when anyone outside of the vehicle is within the minimum safe distance from the antenna as specified in

Table 1-1.

5. Vehicles Powered By Liquefied Petroleum (LP) Gas

Radio installation in vehicles powered by liquefied petroleum gas, where the LP gas container is located

in the trunk or other sealed-off space within the interior of the vehicle, must conform to the National Fire

Protection Association Standard NFPA 58. This requires:

a. The space containing radio equipment is isolated by a seal from the space containing the LP gas

container and its fittings.

b. Outside filling connections are used for the LP gas container.

c. The LP gas container space is vented to the outside of the vehicle.

6. Vehicles Equipped With Airbags

For driver and passenger safety, avoid mounting the Control Head (or any other component) above or

near airbag deployment areas. In addition to driver-side and passenger-side front-impact airbags, some

vehicles may also be equipped with side-impact airbags. For occupant safety, verify the location of all

airbags within the vehicle before installing the radio equipment.
