Reference Information
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 phone 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 energy.
PACEMAKERS
Pacemaker manufacturers recommend that a minimum separation of 6 in (15.3 cm) be
maintained between a wireless phone 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. To minimize the potential for
interference, persons with pacemakers should
• Always keep the device more than 6 in (15.3 cm) from their pacemaker when the device
is switched on
• Not carry the device in a breast pocket
• Hold the device to the ear opposite the pacemaker
If you have any reason to suspect that interference is taking place, switch off your
device immediately.
HEARING AID
Some digital wireless devices may interfere with some hearing aids. If interference occurs,
consult your service provider.
Vehicles
RF signals may affect improperly installed or inadequately shielded electronic systems in
motor vehicles such as electronic fuel injection systems, electronic antiskid (antilock) braking
systems, electronic speed control systems, 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 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 enhancements. For vehicles equipped
with an air bag, remember that an 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.
