Additional safety information
Your device and its enhancements may contain small parts. Keep them out of the reach of 
small children.
Operating environment
Warning! For safety reasons, turn off all wireless or radio transmitting 
devices when using your smartphone device under the following 
conditions. These devices may include, but are not limited to: wireless 
LAN (WLAN), Bluetooth and/or 3G.
Remember to follow any special regulations in force in any area, and always switch off your 
device when its use is prohibited or when it may cause interference or danger. Use the device 
only in its normal operating positions. To successfully transmit data files or messages, this 
device requires a good quality connection to the network. In some cases, transmission of data 
files or messages may be delayed until such a connection is available. Ensure that the above 
separation distance instructions are followed until the transmission is completed. Parts of the 
device are magnetic. Metallic materials may be attracted to the device, and persons with 
hearing aids should not hold the device to the ear with the hearing aid. Do not place credit 
cards or other magnetic storage media near the device, because information stored on them 
may be erased.
Medical devices
Operation of any radio transmitting equipment, including wireless phones, may interfere with 
the functionality of inadequately protected medical devices. Consult a physician or the 
manufacturer of the medical device to determine if they are adequately shielded from external 
RF energy or if you have any questions. Switch off your device in health care facilities when 
any regulations posted in these areas instruct you to do so. Hospitals or health care facilities 
may be using equipment that could be sensitive to external RF transmissions.
Pacemakers. Pacemaker manufacturers recommend that a minimum separation of 15.3 cm 
(6) be maintained between wireless devices and a pacemaker to avoid potential interference 
with the pacemaker. These recommendations are consistent with the independent research by 
and recommendations of Wireless Technology Research. Persons with pacemakers should do 
the following:
• Always keep the device more than 15.3 cm (6) from the pacemaker.
• Not carry the device near your pacemaker when the device is switched on. If you 
suspect interference, switch off your device, and move it.
Hearing aids. Some digital wireless devices may interfere with some hearing aids. If 
interference occurs, consult your service provider.

Ve h i c l e s
RF signals may affect improperly installed or inadequately shielded electronic systems in motor 
vehicles such as electronic fuel injection systems, electronic anti-skid (anti-lock) braking 
systems, electronic speed control systems, and air bag systems. For more information, check 
with the manufacturer, or its representative, of your vehicle or any equipment that has been 
added. Only qualified personnel should service the device, or install the device in a vehicle. 
Faulty installation or service may be dangerous and may invalidate any warranty that may 
apply to the device. Check regularly that all wireless 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 enhancements. For vehicles equipped with an 
air bag, remember that air bags inflate with great force. Do not place objects, including installed 
or portable wireless equipment in the area over the air bag or in the air bag deployment area. If 
in-vehicle wireless equipment is improperly installed, and the air bag inflates, serious injury 
could result. Using your device while flying in aircraft is prohibited. 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, disrupt the wireless telephone network, and may be illegal.
Potentially explosive environments
Switch off your device when in any area with a potentially explosive atmosphere and obey all 
signs and instructions. Potentially explosive atmospheres include areas where you would 
normally be advised to turn off your vehicle engine. Sparks in such areas could cause an 
explosion or fire resulting in bodily injury or even death. Switch off the device at refueling points 
such as near gas pumps at service stations. Observe restrictions on the use of radio 
equipment in fuel depots, storage, and distribution areas; chemical plants; or where blasting 
operations are in progress. Areas with a potentially explosive atmospheres are often, but not 
always, clearly marked. They include below deck on boats, chemical transfer or storage 
facilities, vehicles using liquefied petroleum gas (such as propane or butane), and areas where 
the air contains chemicals or particles such as grain, dust or metal powders. 
Follow any restrictions. Do not use the device where blasting is in progress.
Emergency calls
Important: Wireless phones, including this device, operate using radio signals, wireless 
networks, landline networks, and user-programmed functions. Because of this, connections in 
all conditions cannot be guaranteed. You should never rely solely on any wireless device for 
essential communications like medical emergencies.
If certain features are in use, you may first need to turn those features off before you can make 
an emergency call. Consult this guide or your service provider for more information.
When making an emergency call, give all the necessary information as accurately as possible. 
Your wireless device may be the only means of communication at the scene of an accident. Do 
not end the call until given permission to do so.
