Read all safety instructions for any products and accessories before using with 

iPhone. Apple is not responsible for the operation of third-party accessories or their 

compliance with safety and regulatory standards.
When you use the Apple USB Power Adapter to charge iPhone, make sure that 

the power adapter is fully assembled before you plug it into a power outlet. Then 

insert the Apple USB Power Adapter firmly into the power outlet. Do not connect 

or disconnect the Apple USB Power Adapter with wet hands. Do not use any power 

adapter other than the Apple USB Power Adapter to charge iPhone.
The Apple USB Power Adapter may become warm during normal use. Always allow 

adequate ventilation around the Apple USB Power Adapter and use care when 

handling. Unplug the Apple USB Power Adapter if any of the following conditions 

exist: 

The power cord or plug has become frayed or damaged. 
The adapter is exposed to rain, liquid, or excessive moisture. 
The adapter case has become damaged. 
You suspect the adapter needs service or repair. 
You want to clean the adapter. 

Permanent hearing loss may occur if the receiver, earbuds, headphones, 

speakerphone, or earpieces are used at high volume. Set the volume to a safe level. 

You can adapt over time to a higher volume of sound that may sound normal but 

can be damaging to your hearing. If you experience ringing in your ears or muffled 

speech, stop listening and have your hearing checked. The louder the volume, the 

less time is required before your hearing could be affected. Hearing experts suggest 

that to protect your hearing: 

Limit the amount of time you use the receiver, earbuds, headphones, 

speakerphone, or earpieces at high volume. 
Avoid turning up the volume to block out noisy surroundings. 
Turn the volume down if you can’t hear people speaking near you. 

For information about how to set a maximum volume limit on iPhone, see the 

You should not rely on wireless devices for essential communications, such as 

medical emergencies. Use of iPhone to call emergency services may not work in 

all locations. Emergency numbers and services vary by region, and sometimes an 

emergency call cannot be placed due to network availability or environmental 

interference. Some cellular networks may not accept an emergency call from 

iPhone if it does not have a SIM, the SIM is PIN-locked, or if you have not activated 

your iPhone.
