Warnings and precautions
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 network provider.
Vehicles
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
