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.
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, and air bag systems.

representative, of your vehicle or any equipment that has been
