Safety, Handling, & Support
Important safety information
WARNING:  Failure to follow these safety instructions could result in fire, electric shock, or other 
injuries, or damage to iPhone or other property. Read all the safety information below before 
using iPhone.
Handling  Handle iPhone with care. It is made of metal, glass, and plastic and has sensitive 
electronic components inside. iPhone can be damaged if dropped, burned, punctured, or 
crushed, or if it comes in contact with liquid. Don’t use a damaged iPhone, such as one with a 
cracked screen, as it may cause injury. If you’re concerned about scratching the surface of iPhone, 
consider using a case or cover.
Repairing  Don’t open iPhone and don’t attempt to repair iPhone by yourself. Disassembling 
iPhone may damage it or may cause injury to you. If iPhone is damaged, malfunctions, or comes 
in contact with liquid, contact Apple or an Apple Authorized Service Provider. You can find more 
information about getting service at www.apple.com/support/iphone/service/faq .
Battery  Don’t attempt to replace the iPhone battery yourself—you may damage the battery, 
which could cause overheating and injury. The lithium-ion battery in iPhone should be replaced 
only by Apple or an Apple Authorized Service Provider, and must be recycled or disposed of 
separately from household waste. Don’t incinerate the battery. For information about battery 
recycling and replacement, see www.apple.com/batteries .
Distraction  Using iPhone in some circumstances can distract you and may cause a dangerous 
situation. Observe rules that prohibit or restrict the use of mobile phones or headphones (for 
example, avoid texting while driving a car or using headphones while riding a bicycle).
Navigation  Maps, directions, Flyover, and location-based apps depend on data services.
Charging  Charge iPhone with the included USB cable and power adapter, or with 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.
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 find out if your micro USB power adapter complies with 
these standards.
Appendix 
						

							 Appendix D    Safety, Handling, & Support 15 2
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 www.apple.com/sound . For information about how 
to set a maximum volume limit on iPhone, see Music settings
 on page 66.
WARNING:  To pre vent 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. 
						

							 Appendix D    Safety, Handling, & Support 15 3
Repetitive motion  When you perform repetitive activities such as typing or playing games 
on iPhone, you may experience occasional discomfort in your hands, arms, wrists, shoulders, 
neck, or other parts of your body. If you experience discomfort, stop using iPhone and consult 
a physician.
High-consequence activities  This device is not intended for use where the failure of the device 
could lead to death, personal injury, or severe environmental damage.
Choking hazard  Some iPhone accessories may present a choking hazard to small children. Keep 
these accessories away from small children.
Important handling information
Cleaning  Clean iPhone immediately if it comes in contact with anything that may cause stains—
such as dirt, ink, makeup, or lotions. To clean:
 •Disconnect all cables and turn iPhone off (press and hold the Sleep/Wake button, then slide 
the onscreen slider).
 •Use a soft, lint-free cloth.
 •Avoid getting moisture in openings.
 •Don’t use cleaning products or compressed air.
The front or back cover of iPhone may be made of glass with a fingerprint-resistant oleophobic 
(oil repellant) coating. This coating wears over time with normal usage. Cleaning products and 
abrasive materials will further diminish the coating, and may scratch the glass.
Using connectors, ports, and buttons  Never force a connector into a port or apply excessive 
pressure to a button, because this may cause damage that is not covered under the warranty. If 
the connector and port don’t join with reasonable ease, they probably don’t match. Check for 
obstructions and make sure that the connector matches the port and that you have positioned 
the connector correctly in relation to the port.
Lightning cable  Discoloration of the Lightning plug after regular use is normal. Dirt, debris, and 
exposure to liquids may cause discoloration. To remove the discoloration or if the cable becomes 
warm during use or won’t charge or sync your iPhone, disconnect the Lightning cable from your 
computer or power adapter and clean it with a soft, dry, lint-free cloth. Do not use liquids or 
cleaning products when cleaning the Lightning connector.
Operating temperature  iPhone is designed to work in ambient temperatures between 32° and 
95° F (0° and 35° C) and stored in temperatures between -4° and 113° F (-20° and 45° C). iPhone 
can be damaged and battery life shortened if stored or operated outside of these temperature 
ranges. Avoid exposing iPhone to dramatic changes in temperature or humidity. When you’re 
using iPhone or charging the battery, it is normal for iPhone to get warm.
If the interior temperature of iPhone exceeds normal operating temperatures (for example, in a 
hot car or in direct sunlight for extended periods of time), you may experience the following as it 
attempts to regulate its temperature:
 •iPhone stops charging.
 •The screen dims.
 •A temperature warning screen appears.
 •Some apps may close. 
						

							 Appendix D    Safety, Handling, & Support 15 4
Important:  You may not be able to use iPhone while the temperature warning screen is 
displayed. If iPhone can’t regulate its internal temperature, it goes into deep sleep mode until 
it cools. Move iPhone to a cooler location out of direct sunlight and wait a few minutes before 
trying to use iPhone again.

Cellular settings
Use Cellular settings to turn cellular data and roaming on or off, set which apps and services use 
cellular data, see call time and cellular data usage, and set other cellular options.
If iPhone is connected to the Internet via the cellular data network, the LTE, 4G, 3G, E, or GPRS 
icon appears in the status bar.
LTE, 4G, and 3G service on GSM cellular networks support simultaneous voice and data 
communications. For all other cellular connections, you can’t use Internet services while you’re 
talking on the phone unless iPhone also has a Wi-Fi connection to the Internet. Depending on 
your network connection, you may not be able to receive calls while iPhone transfers data over 
the cellular network—when downloading a webpage, for example.
 •GSM networks:  On an EDGE or GPRS connection, incoming calls may go directly to voicemail 
during data transfers. For incoming calls that you answer, data transfers are paused.
 •CDMA networks:  On EV-DO connections, data transfers are paused when you answer incoming 
calls. On 1xRTT connections, incoming calls may go directly to voicemail during data transfers. 
For incoming calls that you answer, data transfers are paused.
Data transfer resumes when you end the call. 
						

							 Appendix D    Safety, Handling, & Support 15 8
If Cellular Data is off, all data services use only Wi-Fi—including email, web browsing, push 
notifications, and other services. If Cellular Data is on, carrier charges may apply. For example, 
using certain features and services that transfer data, such as Siri and Messages, could result in 
charges to your data plan.
Turn Cellular Data on or off. Go to Settings > Cellular. The following options may also be available:
 •Turn Voice Roaming on or off (CDMA):  Turn Voice Roaming off to avoid charges from using other 
carrier’s networks. When your carrier’s network isn’t available, iPhone won’t have cellular (data 
or voice) service.
 •Turn Data Roaming on or off:  Data Roaming permits Internet access over a cellular data 
network when you’re in an area not covered by your carrier’s network. When you’re traveling, 
you can turn off Data Roaming to avoid roaming charges. See Phone settings
 on page 49 .
 •Enable or disable 3G:  Using 3G loads Internet data faster in some cases, but may decrease 
battery performance. If you’re making a lot of phone calls, you may want to turn 3G off to 
extend battery life. This option is not available in all areas.
Set whether cellular data is used for apps and services. Go to Settings > Cellular, then turn 
cellular data on or off for any app that can use cellular data. If a setting is off, iPhone uses only 
Wi-Fi for that service. The iTunes setting includes both iTunes Match and automatic downloads 
from the iTunes Store and the App Store.
