RF Energy Exposure Awareness and Control Information, and
Operational Instructions for FCC Occupational Use Requirements
Before using your portable two-way Radio, read this important RF Energy Awareness
And Control Information And Operational Instructions to ensure compliance with the
FCC’s 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 meet FCC
limits. This radio device is NOT authorized for general population, consumer, or any
other 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, 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 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 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.

Federal Communications Commission 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
x 5100 ES Models II/III Portable Radio Operating Manual March 2008
information. Your EFJohnson two-way radio has a RF exposure product label. Also, your
EFJohnson user manual, or product 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 EFJohnson 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 and ICNIRP
exposure limits for occupational/controlled RF exposure environment at operating duty
factors of up to 50% transmitting and is authorized by the FCC for occupational use only.
In terms of measuring RF energy for compliance with the FCC exposure guidelines, your
radio radiates 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 the FCC occupational
RF exposure limits and may operate at duty factors of up to 50% talk.
Your EFJohnson two-way radio complies with the following RF energy exposure
standards and guidelines:
• United States Federal Communications Commission, Code of Federal Regulations; 47
CFR §§ 1.1307, 1.1310, 2.1091 and 2.1093
• 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
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 the device when it is 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).
• Hold the radio in a vertical position in front of face with the microphone (and the other
parts of the radio, including the antenna) at least one inch (2.5 cm) away from the nose.
Keeping the radio at the proper distance is important because RF exposures decrease
with distance from the antenna. The antenna should be kept away from eyes.
• When worn on the body, always place the radio in an EFJohnson approved clip, holder,
holster, case, or body harness for this product. Using approved body-worn accessories is
important because the use of EFJohnson or other manufacturer’s non-approved
accessories may result in exposure levels which exceed the FCC’s 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, then ensure the antenna and the radio are kept at least
one inch (2.5 cm) from the body when transmitting. Keeping the radio at the proper
distance is important because RF exposures decrease with increasing distance from the
antenna.
• Use only EFJohnson approved supplied or replacement antennas, batteries, and
accessories. Use of non-EFJohnson approved antennas, batteries, and accessories may
exceed the FCC RF exposure guidelines.
• For a list of EFJohnson approved accessories, see the service manual or marketing
accessory lists or contact the E.F. Johnson Company.

Electromagnetic Interference
This device complies with Part 15 of the FCC rules. Operation is subject to the condition
that this device does not cause harmful interference. In addition, changes or modification
to this equipment not expressly approved by the E.F. Johnson Company could void the
user’s authority to operate this equipment (FCC Rules, 47CFR Part 15.19).
Usage Compatibility
Do NOT operate it in areas that are sensitive to RF energy such as aircraft, hospitals,
blasting sites, and fuel storage sites. Areas with potentially flammable atmospheres are
usually, but not always, clearly posted. These may include gas stations, fuel and chemical
storage and transfer stations, below deck on boats, and areas where the air contains
flammable chemicals or particles such as grain dust or metal powders.
Battery Disposal
Dispose of the nickel metal-hydride (NiMH) or Lithium-Ion (Li-Ion) battery used by this
radio in accordance with local regulations. Do NOT dispose of it in fire because it can
explode. Also, do not short the terminals because it may become very hot.
