Pacemakers
Pacemaker manufacturers recommend 
that a minimum separation of 
15.3 centimeters (6 inches) 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. Persons with 
pacemakers should do the following:
• Always keep the device more than 
15.3 centimeters (6 inches) from the 
pacemaker.
• Not carry the device in a breast 
pocket.
• Hold the device to the ear opposite 
the pacemaker to minimize the 
potential for interference.
If you suspect interference, switch off 
your device, and move the device away.
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. 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 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
