Hearing
Warning:
When you use the headset, your ability to hear outside sounds may be affected. Do not use the headset where it can endanger
your safety.
Some wireless devices may interfere with some hearing aids.
Operating environment
This device meets RF exposure guidelines in the normal use position at the ear or at least 2.2 centimeters (7/8 inch) away from
the body. Any carry case, belt clip, or holder for body-worn operation should not contain metal and should position the device
the above-stated distance from your body.
To send data files or messages requires a quality connection to the network. Data files or messages may be delayed until such
a connection is available. Follow the separation distance instructions until the transmission is completed.
Parts of the device are magnetic. Metallic materials may be attracted to the device. Do not place credit cards or other magnetic
storage media near the device, because information stored on them may be erased.
Vehicles
RF signals may affect improperly installed or inadequately shielded electronic systems in motor vehicles such as electronic fuel
injection, electronic antilock braking, electronic speed control, and air bag systems. For more information, check with the
manufacturer of your vehicle or its equipment.
Only qualified personnel should service the device or install the device in a vehicle. Faulty installation or service may be
dangerous and may invalidate your warranty. Check regularly that all wireless device equipment in your vehicle is mounted
and operating properly. Do not store or carry flammable liquids, gases, or explosive materials in the same compartment as the
device, its parts, or accessories. Remember that air bags inflate with great force. Do not place your device or accessories in the
air bag deployment area.
Switch off your device before boarding an aircraft. The use of wireless teledevices in an aircraft may be dangerous to the
operation of the aircraft and may be illegal.
Potentially explosive environments
Switch off your device in any area with a potentially explosive atmosphere. Obey all posted instructions. Sparks in such areas
could cause an explosion or fire resulting in bodily injury or death. Switch off the device at refueling points such as near gas
pumps at service stations. Observe restrictions in fuel depots, storage, and distribution areas; chemical plants; or where blasting
operations are in progress. Areas with a potentially explosive atmosphere are often, but not always, clearly marked. They include
areas where you would be advised to turn off your vehicle engine, below deck on boats, chemical transfer or storage facilities
and where the air contains chemicals or particles such as grain, dust, or metal powders. You should check with the manufacturers
of vehicles using liquefied petroleum gas (such as propane or butane) to determine if this device can be safely used in their
vicinity.
Certification information (SAR)
This mobile device meets guidelines for exposure to radio waves.
Your mobile device is a radio transmitter and receiver. It is designed not to exceed the limits for exposure to radio waves
recommended by international guidelines. These guidelines were developed by the independent scientific organization ICNIRP
and include safety margins designed to assure the protection of all persons, regardless of age and health.
The exposure guidelines for mobile devices employ a unit of measurement known as the Specific Absorption Rate or SAR. The
SAR limit stated in the ICNIRP guidelines is 2.0 watts/kilogram (W/kg) averaged over 10 grams of tissue. Tests for SAR are
conducted using standard operating positions with the device transmitting at its highest certified power level in all tested
frequency bands. The actual SAR level of an operating device can be below the maximum value because the device is designed
to use only the power required to reach the network. That amount changes depending on a number of factors such as how
close you are to a network base station.
