This two-way radio uses electromagnetic energy in the radio frequency
(RF) spectrum to provide communications between two or more users
over a distance. RF energy, which when used improperly, can cause
biological damage.
All Retevis two-way radios are designed, manufactured, and tested to en-
sure 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.who.int/en/
Local Government Regulations
When two-way radios are used as a consequence of employment, 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
two-way radio 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.

ent 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.
Protect your hearing:
• Use the lowest volume necessary to do your job.
• Turn up the volume only if you are in noisy surroundings.
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 Tran-
smit (Talk), push the Push to Talk (PTT) button. To receive calls (listen),
release the PTT button. Transmitting 50% of the time, or less, is import-
ant 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 recomme-
nded 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 RF exposure limits.
Hand-held Mode
• Hold the radio in a vertical position with the microphone (and
other parts of the radio including the antenna) at least 2.5 cm
(one inch) away from the nose or lips. The antenna should be
kept away from the eyes. Keeping the radio at a proper distance is
important as RF exposure decreases with increasing distance from the
antenna.
Phone Mode
• When placing or receiving a phone call, hold your radio product as you
would a wireless telephone. Speak directly into the microphone.

volume.
• When using the radio without a headset or earpiece, do not
place the radio's speaker directly against your ear
• Use careful with the earphone maybe possible excess-
ive sound pressure from earphones and headphones
can cause hearing loss
Note: Exposure to loud noises from any source for extended
periods of time may temporarily or permanently affect your
hearing. The louder the radio's volume, the less time is
required before your hearing could be affected. Hearing
damage from loud noise is sometimes undetectable at
first and can have a cumulative effect.
Avoid Burns
Antennas
• Do not use any portable radio that has a damaged antenna. If
a damaged antenna comes into contact with the skin when the
radio is in use, a minor burn can result.
Batteries (If appropriate)
• When the conductive material such as jewelry, keys or chains
touch exposed terminals of the batteries, may complete an
electrical circuit (short circuit the battery) and become hot to
cause bodily injury such as burns. Exercise care in handling
any battery, particularly when placing it inside a pocket, purse
or other container with metal objects
Long transmission
• When the transceiver is used for long transmissions, the
radiator and chassis will become hot.
