Appendix C Safety, Handling, & Support 147
Charging Charge iPhone with the included USB cable and power adapter or other third-party
“Made for iPhone” cables and power adapters that are compatible with USB 2.0 or power
adapters compliant with one or more of the following standards EN 301489-34, IEC 62684,
YD/T 1591-2009, CNS 15285, ITU L.1000, or another applicable mobile phone power adapter
interoperability standard. An iPhone Micro USB Adapter (available separately in some areas) or
other adapter may be needed to connect iPhone to some compatible power adapters. Using
damaged cables or chargers, or charging when moisture is present, can cause electric shock.
When you use the Apple USB Power Adapter to charge iPhone, make sure that the AC plug or
AC power cord is fully inserted into the adapter before you plug it into a power outlet. Power
adapters may become warm during normal use, and prolonged contact may cause injury. Always
allow adequate ventilation around power adapters when using them.
Note: Only micro USB power adapters in certain regions that comply with applicable
mobile phone power adapter interoperability standards are compatible. Please contact the
power adapter manufacturer to nd out if your micro USB power adapter complies with
these standards.
Hearing loss Listening to sound at high volumes may damage your hearing. Background noise,
as well as continued exposure to high volume levels, can make sounds seem quieter than they
actually are. Turn on the audio and check the volume before inserting anything in your ear. For
more information about hearing loss, see www.apple.com/sound. For information about how to
set a maximum volume limit on iPhone, see Music settings on page 63.
WARNING: To prevent possible hearing damage, do not listen at high volume levels for
long periods.
Apple headsets The headsets sold with iPhone 4S or later in China (identiable by dark
insulating rings on the plug) are designed to comply with Chinese standards and are compatible
with iPhone 4S or later, iPad 2 or later, and iPod touch 5th generation. Use only compatible
headsets with your device.
Radio signals iPhone uses radio signals to connect to wireless networks. For information about
the amount of power used to transmit these signals, and about steps you can take to minimize
exposure, see Settings > General > About > Legal > RF Exposure.
Radio frequency interference Observe signs and notices that prohibit or restrict the use
of mobile phones (for example, in healthcare facilities or blasting areas). Although iPhone is
designed, tested, and manufactured to comply with regulations governing radio frequency
emissions, such emissions from iPhone can negatively aect the operation of other electronic
equipment, causing them to malfunction. Turn o iPhone or use Airplane Mode to turn o the
iPhone wireless transmitters when use is prohibited, such as while traveling in aircraft, or when
asked to do so by authorities.
Medical devices iPhone contains radios that emit electromagnetic elds. These electromagnetic
elds may interfere with pacemakers or other medical devices. If you wear a pacemaker, maintain
at least 6 inches (approximately 15 cm) of separation between your pacemaker and iPhone. If
you suspect iPhone is interfering with your pacemaker or any other medical device, stop using
iPhone and consult your physician for information specic to your medical device. iPhone has
magnets near the bottom, and the included headphones also have magnets in the earbuds,
which may interfere with pacemakers, debrillators or other medical devices. Maintain at least 6
inches (approximately 15 cm) of separation between your pacemaker or debrillator and iPhone
or the earbuds.
