Retevis RT642 Mode D'emploi page 8

• During transmissions, your radio generates RF energy that can possibly
cause interference with other devices or systems. To avoid such interf-
erence, turn off the radio in areas where signs are posted to do so.
• DO NOT operate the transmitter in areas that are sensitive to electrom-
agnetic radiation such as hospitals, aircraft, and blasting sites.
• Portable Device, this transmitter may operate with the antenna(s)
documented in this filing in Push-to-Talk and body-worn configurations.
RF exposure compliance is limited to the specific belt-clip and accessory
configurations as documented in this filing and the separation distance
between user and the device or its antenna shall be at least 2.5 cm.
• Mobile Device, during operation, the separation distance between user
and the antenna subjects to actual regulations, this separation distance
will ensure that there is sufficient distance from a properly installed
externally-mounted antenna to satisfy the RF exposure requirements.
• Occupational/Controlled Radio, this radio is designed for and classified
as "Occupational/Controlled Use Only", meaning it must be used only
during the course of employment by individuals aware of the hazards,
and the ways to minimize such hazards; NOT intended for use in a
General population/uncontrolled environment.
• General population/uncontrolled Radio, this radio is designed for and
classified as "General population/uncontrolled Use".
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 recom-
mended minimum lateral distance away from a properly installed
12
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.
Electromagnetic Interference/Compatibility
NOTE: Nearly every electronic device is susceptible to electromagnetic
interference (EMI) if inadequately shielded, designed, or otherwise
configured for electromagnetic compatibility.
Avoid Choking Hazard
Small Parts. Not for children under 3 years.
Turn off your radio power in the following conditions:
• Turn off your radio before removing (installing) a battery or
accessory or when charging battery.
• Turn off your radio when you are in a potentially hazardous
WARNING
environments: Near electrical blasting caps, in a blasting
area, in explosive atmospheres (inflammable gas, dust
particles, metallic powders, grain powders, etc.).
• Turn off your radio while taking on fuel or while parked at
gasoline service stations.
To avoid electromagnetic interference and/or compatibility
conflicts
• Turn off your radio in any facility where posted notices inst-
ruct you to do so, hospitals or health care facilities (Pacem-
akers, Hearing Aids and Other Medical Devices) may be
