Safety, Handling, & Support

Prolonged heat exposure  iPhone and its power adapter comply with applicable surface 
temperature standards and limits. However, even within these limits, sustained contact with 
warm surfaces for long periods of time may cause discomfort or injury. Use common sense 
to avoid situations where your skin is in contact with a device or its power adapter when it’s 
operating or plugged into a power source for long periods of time. For example, don’t sleep or 
place a device or power adapter under a blanket, pillow, or your body when it’s plugged into a 
power source. It’s important to keep iPhone and its power adapter in a well-ventilated area when 
using or charging them. Take special care if you have a physical condition that affects your ability 
to detect heat against the body.
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. Use only compatible receivers, earbuds, headphones, speakerphones, or earpieces 
with your device. Turn on the audio and check the volume before inserting anything in your ear. 
For more information about hearing loss, see 
. For information about how 
to set a maximum volume limit on iPhone, see 
 on page 66.
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 (identifiable 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 affect the operation of other electronic 
equipment, causing them to malfunction. Turn off iPhone or use Airplane Mode to turn off 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 fields, and contains 
magnets near the bottom. The included headphones also have magnets in the earbuds. These 
electromagnetic fields and magnets may interfere with pacemakers, defibrillators, or other 
medical devices. Maintain at least 6 inches (approximately 15 cm) of separation between your 
pacemaker or defibrillator and iPhone or the earbuds. If you suspect iPhone is interfering with 
your pacemaker or any other medical device, stop using iPhone and consult your physician for 
information specific to your medical device.
Medical conditions  If you have any other medical condition that you believe could be affected 
by iPhone (for example, seizures, blackouts, eyestrain, or headaches), consult with your physician 
prior to using iPhone. 
Explosive atmospheres  Do not charge or use iPhone in any area with a potentially explosive 
atmosphere, such as a fueling area, or in areas where the air contains chemicals or particles (such 
as grain, dust, or metal powders). Obey all signs and instructions.
