RF Safety
This two-way radio uses electromagnetic energy in the radio frequency (RF) spectrum to provide communica-
tions between two or more users over a distance. RF energy, which when used improperly, can cause
biological damage. 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://ww-
w.who.int/en/
Keeping the radio at a proper distance is important as RF exposure decreases with increasing distance from
the proper antenna. A proper antenna is an antenna supplied with this radio by the manufacturer or
specifically authorized by the local authority for use with this radio. This radio can only be operated by use of
an antenna of a type and maximum (or lesser) gain approved for the transmitter under regulations and rules.
This transmitter must operate with the antenna(s) documented and in Push-to-Talk and body-worn
configurations as documented. Using authorized accessories is important because the use of Non-Retevis
accessories may result in exposure levels, which exceed the IEEE/ICNIRP RF exposure limits.
Transmit no more than the rated duty factor 50% of the time. Transmitting necessary information or less, is
important because the radio generates measurable RF energy exposure only when transmitting in terms of
measuring for standards compliance. For users who wish to further reduce their exposure, some effective
measures to reduce RF exposure include:
•Reduce the amount of time spent using your wireless device.
•Use a speakerphone, earpiece, headset, or other hands-free accessory to reduce proximity to the head
(and thus head exposure). While wired earpieces may conduct some energy to the head and wireless
earpieces also emit a small amount of RF energy, both wired and wireless earpieces remove the greatest
source of RF energy (handheld device) from proximity to the head and thus can greatly reduce total exposure
to the head.
•Increase the distance between wireless devices and your body.
•This radio is designed for and classified as "Occupational/Controlled Use Only". Occupational/Controlled
environments are defined as locations where there is exposure that may be incurred by people who are aware
of the potential of exposure, for example, as a result of employment or occupation. It means a radio must be
used only by individuals aware of the hazards, and the ways to minimize such hazards;
Not intended for use in a General population/uncontrolled environment.
Hand-held Mode：
•To control your exposure and ensure compliance with the controlled environment exposure
limits, always adhere to the following procedure:
-To transmit (talk), press the Push-to-Talk (PTT) button in front of the face.
-Hold the radio in a vertical position 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.
Electromagnetic Interference/Compatibility
Nearly every electronic device is susceptible to electromagnetic interference (EMI) if inadequately shielded,
designed, or otherwise configured for electromagnetic compatibility. During transmissions, your radio
generates RF energy that can possibly cause interference with other devices or systems. To avoid such
interference, turn off the radio in areas where signs are posted to do so, such as hospitals or healthcare
facilities.
Persons with pacemakers, implantable cardioverter defibrillators (ICDs) or other active implantable medical
devices should:
• 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 there is 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 the body from the implantable device to minimize the potential for interference.
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.
Turn off your radio in the following conditions:
•Turn off your radio prior to entering any area with a potentially hazardous or explosive atmosphere. Only
radio types that are especially qualified should be used in such areas as "Intrinsically Safe".
Note: the areas with potentially explosive atmosphere referred to above include blasting caps, blasting areas,
inflammable gas, dust particles, metallic powders, grain powders, fueling areas such as below decks on boats,
fuel or chemical transfer or storage facilities, areas where the air contains chemicals or particles (such as
grain, dust or metal powders) and any other area where you would normally be advised to turn off your
