shock, injury, or damage to iPhone or other property. When you use the Apple USB Power
Adapter to charge iPhone, make sure the USB cable is fully inserted into the power adapter
before you plug the adapter into a power outlet.
Lightning cable and connector Avoid prolonged skin contact with the connector when the
Lightning to USB Cable is plugged into a power source because it may cause discomfort or
injury. Situations such as sleeping or sitting on the Lightning connector should be avoided.
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 on a
device or power adapter, or place them 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

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 audio playback 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 72.
To avoid hearing damage, use only compatible receivers, earbuds, headphones, speakerphones,
