RF ENERGY EXPOSURE AND PRODUCT SAFETY
GUIDE FOR PORTABLE WALKIE TALKIE
This walkie talkie uses electromagnetic energy in the
radio frequency (RF) spectrum to provide communicati-
ons 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 electroma-
gnetic 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 Retevis walkie talkie are designed, manufactured,
and tested to ensure they meet government-established
Warnings
ATTENTION!
Before using this radio, read this guide which
contains important operating instructions for
safe usage and RF energy awareness and
control for compliance with applicable stan-
dards and regulations.
Exclusions from Warranty Coverage
•To any product damaged by accident.
•In the event of misuse or abuse of the product or as a
result of unauthorized alterations or repairs.
If the serial number has been altered, defaced,
or removed.

RF exposure levels. In addition, manufacturers also
recommend specific operating instructions to users of
walkie talkie. 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.who.int/en
Local Government Regulations
When walkie talkie are used as a consequence of em-
ployment, the Local Government Regulations 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 Retevis walkie talkie has a RF
Exposure Product Label. Also, your Retevis user
manual, or separate safety booklet includes information
and operating instructions required to control your RF
exposure and to satisfy compliance requirements.
Radio License
Governments keep the radios in classification, most
of the classified walkie-talkie need to get local
government License, and operation is allowed. The
detailed classification and the use of your two radios,
please contact the local government radio management
departments. For the following specified classification:
the USA FRS, Australian CB, the individual license is
not required.
Compliance with RF Exposure Standards (If
appropriate, Reference to the actual product’s
Safety Marking)
Your Retevis walkie talkie is designed and tested to
comply with a number of national and International
standards and guidelines (listed below) for human
exposure to radio frequency electro-magnetic energy.
FCC ID
The FCCID means: 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
approved for occupational use only.
IC ID
This device complies with Industry Canada
license-exempt RSS standard(s). Operation is subject
to the following two conditions:
(1) This device may not cause interference, and
(2) This device must accept any interference, including
interference that may cause undesired operation of
the device.
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.

RF energy exposure standards and guidelines (if
appropriate)
Your Retevis walkie talkie complies with the following
RF energy exposure standards and guidelines:
• United States Federal Communications Commission
(FCC), Code of Federal Regulations; 47 CFR part 2
sub-part J.
• American National Standards Institute (ANSI) /
Institute of Electrical & Electronic Engineers (IEEE)
C95. 1-2005
• IEEE Std. 1528:2013 and KDB447498, Evaluating
Compliance with FCC Guidelines for Human Exposure
to Radio Frequency Electromagnetic Fields.
• Institute of Electrical and Electronic Engineers
(IEEE) C95.3-2002
• International Commission on Non-Ionizing Radiation
Protection (ICNIRP)
• Ministry of Health (Canada) Safety Code 6 & Industry
Canada RSS-102.
• International Electrotechnical Com-mission
IEC62209-2:2010]
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:
• User awareness instructions should accompany the
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 (listen), release the
PTT button. Transmitting 50% of the time, or less, is
important because the radio generates measurable
RF energy exposure only when transmitting in terms
of measuring for standards compliance.
• Transmit only when people outside the vehicle are at
least the recommended minimum lateral distance
away from a properly installed according to installation
instructions, externally mounted antenna.
• When operating in front of the face, worn on the body,
always place the radio in a Retevis approved clip,
holder, holster, case, or body harness for this product.
Using approved body-worn accessories is important
because the use of Non-Retevis approved accessories
may result in exposure levels, which exceed the IEEE
/ICNIRP 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 or at the body in the PTT mode or
alongside of the head in the phone mode, then ensure
the antenna and the radio are kept 2.5 cm (one inch)
from the body when transmitting. Keeping the radio at
a proper distance is important because RF exposures
decrease with increasing distance from the antenna.
Hand-held Mode
• Hold the radio in a vertical position with
the microphone (and other parts of the
radio including the antenna) atleast 2.5cm

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 (Pacemakers, Hearing Aids and
Other Medical Devices) may be using equip-
ment that is sensitive to external RF energy.
• 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.

Devices Persons with pacemakers, Implantable
Cardioverter-Defibrillators (ICDs) or other active
implantable medical devices (AIMD) should:
• ALWAYS keep the radio more than 15cm from
their pacemaker when the radio is turned on.
• Consult with their physicians regarding the
potential risk of interference from radio
frequency transmitters, such as portable
radios (poorly shielded medical devices may
be more susceptible to interference).
• Turn the radio OFF immediately if they have
any reason to suspect that interference is
taking place.
• Do not carry the radio in a chest pocket or
near the implantation site, and carry or use
the radio on the opposite side of their body
from the implantable device to minimize the
potential for interference.
(one inch) away from the nose or lips.
