Additional Information
For more information from the FCC about exposure to RF energy, see:
www.fcc.gov/oet/rfsafety
The FCC and the U.S. Food and Drug Administration (FDA) also maintain a consumer
website at www.fda.gov/cellphones to address inquiries about the safety of mobile
phones. Please check the website periodically for updates.
For information about the scientific research related to RF energy exposure, see the
EMF Research Database maintained by the World Health Organization at:

Radio Frequency Interference
Nearly every electronic device is subject to radio frequency interference from external
sources if inadequately shielded or designed, or otherwise not configured to be
compatible. As a result, iPhone may cause interference with other devices. Follow these
instructions to avoid interference problems.
Aircraft
Federal Aviation Administration (FAA) regulations may prohibit using wireless devices
while in the air. For more information about using airplane mode to turn off the iPhone
wireless transmitters, see “Using iPhone on an Airplane” on page 22.
Vehicles
RF signals may affect installed or inadequately shielded electronic systems in motor
vehicles. Check with the manufacturer or its representative regarding your vehicle.
Electronic Devices
Most modern electronic equipment is shielded from RF signals. However, certain
electronic equipment may not be shielded against the RF signals from iPhone.
Pacemakers
The Health Industry Manufacturers Association recommends that a minimum
separation of 6 inches (15 cm) be maintained between a handheld wireless phone and
a pacemaker to avoid potential interference with the pacemaker. Persons with
pacemakers:
 Should always keep iPhone more than six inches from their pacemaker when the
phone is turned on
 Should not carry iPhone in a breast pocket
 Should use the ear opposite the pacemaker to minimize the potential for
interference
If you have any reason to suspect that interference is taking place, turn off iPhone
immediately.
