This section contains important information pertaining to the operating instructions of your device. 
It also contains information about how to use the device safely. Read this information carefully 
before using your device.
Electronic Device
Power off your device if using the device is prohibited. Do not use the device when using the 
device causes danger or interference with electronic devices.
Medical Device•   Follow rules and regulations set forth by hospitals and health care facilities. Do not use your 
device when using the device is prohibited.
•   Pacemaker manufacturers recommend that a minimum distance of 15 cm be maintained 
between a device and a pacemaker to prevent potential interference with the pacemaker. If 
you are using a pacemaker, use the device on the opposite side of the pacemaker and do not 
carry the device in your front pocket.
Potentially Explosive Atmosphere
Power off your device in any area with a potentially explosive atmosphere, and comply with all 
signs and instructions. Areas that may have potentially explosive atmospheres include the areas 
where you would normally be advised to turn off your vehicle engine. Triggering of sparks in such 
areas could cause an explosion or a fire, resulting in bodily injuries or even deaths. Do not power 
on your device at refueling points such as service stations. Comply with restrictions on the use of 
radio equipment in fuel depots, storage, and distribution areas, and chemical plants. In addition, 
adhere to restrictions in areas where blasting operations are in progress. Before using the device, 
watch out for areas that have potentially explosive atmospheres that are often, but not always, 
clearly marked. Such locations include areas below the deck on boats, chemical transfer or 
storage facilities, and areas where the air contains chemicals or particles such as grain, dust, or 
metal powders. Ask the manufacturers of vehicles using liquefied petroleum gas (such as 
propane or butane) whether this device can be safely used in their vicinity.
Traffic Security
Observe local laws and regulations while using the device. In addition, if using the device while 
driving a vehicle, comply with the following guidelines:
•   Concentrate on driving. Your first responsibility is to drive safely.•   Do not talk on the device while driving. Use hands-free accessories.•   When you have to make or answer a call, park the vehicle at the road side before using your 
device.
•   RF signals may affect electronic systems of motor vehicles. For more information, consult the 
vehicle manufacturer.
•   In a motor vehicle, do not place the device over the air bag or in the air bag deployment area. 
Otherwise, the device may hurt you owing to the strong force when the air bag inflates.

Emergency Call
You can use your device for emergency calls in the service area. The connection, however, 
cannot be guaranteed in all conditions. You should not rely solely on the device for essential 
communications.
Certification Information (SAR)
This device meets guidelines for exposure to radio waves.
Your device is a low-power radio transmitter and receiver. As recommended by international 
guidelines, the device is designed not to exceed the limits for exposure to radio waves. These 
guidelines were developed by the independent scientific organization International Commission 
on Non-Ionizing Radiation Protection (ICNIRP) and include safety measures designed to ensure 
safety for all users, regardless of age and health. 
						

							57
The Specific Absorption Rate (SAR) is the unit of measurement for the amount of radio frequency 
energy absorbed by the body when using a device. The SAR value is determined at the highest 
certified power level in laboratory conditions, but the actual SAR level of the device when being 
operated can be well below the value. This is because the device is designed to use the minimum 
power required to reach the network.
The SAR limit also adopted by Europe is 2.0 W/kg averaged over 10 grams of tissue. The highest 
SAR value for this device type when tested at the ear is 0.761 W/kg, and when properly worn on 
the body is 0.617 W/kg.
Disposal and Recycling Information
