performed with the device 25mm from the phantom, Body SAR was performed with the belt clip on the device 0 mm from the phantom. Body SAR was also performed with the headset attached and without.WARNINGAntennas:1)The antenna in the packing is unique, please do not optional change.2)For safe operation, the antenna for the product shall be least 25mm away from    your face, when speaking.3)Switching to other antennas is prohibited and will affect the radio performance.4)DO NOT use any portable radio that has a damaged antenna. If a damaged    antenna comes into contact with your skin, a minor burn can result.WARNINGBatteries:All batteries can cause property damage and/or bodily injury such as burns if a conductive material touches exposed terminals. The conductive material may complete an electrical circuit (short circuit) and become hot.• Exercise care when removing NiMH or AA batteries. Do not use sharp or   conductive tools to remove these batteries.• Exercise care in handling any charged battery, particularly when placing it   inside a pocket, purse or other container with metal objects.• Do not discard your battery in a fire.• Do not replace the battery in any area labeled “Hazardous Atmosphere”.   Any sparks created in a potentially explosive atmosphere can cause explosion   or fire.• Do not disassemble, crush, puncture, shred or otherwise attempt to change   the form of your battery.
• Do not dry a wet battery or damp battery with an appliance or heat source,   such as a hair dryer or microwave oven.• If the radio battery contact area has been submerged in water, dry and clean   the battery contacts before attaching the battery to the radio.WARNINGThe information listed below provides the user with the information needed to make him or her aware of RF exposure, and what to do to as-sure that this radio operates with the FCC RF exposure limits of this radio.Electromagnetic Interference/CompatibilityNote: Nearly every electronic device is susceptible to electromagnetic interference (EMI) if inadequately shielded, designed or otherwise configured for electromagn-etic compatibility.During transmissions, RETEVIS, INC. radio generates RF energy that can possib-ly cause interference with other devices or systems.FacilitiesTo 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 may be using equipment that is sensitive to external RF energy.AircraftWhen instructed to do so, turn off your radio when onboard an aircraft. Any use of a radio must be in accordance with applicable regulations per airline crew instruc-tions.Medical Devices – Pacemakers, Defibrillators or other Implanted Medical DevicesPersons with pacemakers, Implantable cardioverter defibrill-ators (ICDs) or other active implantable medical devices (AIMD) 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 their body from the implantable device to minimize the potential for interference.Hearing AidsSome 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 DevicesIf 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.Use of Communication Devices While DrivingAlways check the laws and regulations on the use of radios in the areas where you drive.• Give full attention to driving and to the road.• Use hands-free operation, if available.• Pull off the road and park before making or answering a call, if driving conditions or regulations so require.For Vehicle with Air BagsRefer to the vehicle manufacturer’s manual prior to installation of electronic equipment to avoid interference with air bag wiring. Do not place a portable radio in the area over an air bag or in the air bag deployment area. Air bags inflate with great force. If a portable radio is placed in the air bag deployment area and the air bag inflates, the radio may be propelled with great force and cause serious injury to occupants of the vehicle.
Potentially Explosive AtmosphereTurn off your radio prior to entering any area with a potentially explosive atmosphere. Only radio types that are especially qualified should be used in such areas as “Intrinsically Safe”. Do not remove, install or charge batteries in such areas. Sparks in a potentially explosive atmosphere can cause an explosion or fire resulting in bodily injury or even death.Note: The areas with potentially explosive atmosphere referred to above include 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 vehicle engine. Areas with potentially explosive atmospheres are often – but not always posted.Blasting Caps and AreasTo avoid possible interference with blasting operations, turn off your radio when you are near electrical blasting caps, in a blasting area, or in areas posted “Turn off two-way radios”. Obey all signs and instructions.WARNING: CHOKING HAZARD – Small Parts. Not for children under 3 years.Attention! RISQUE D’ÉTOUFFEMENT – Contient de petits éléments.
