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 device interference 

iPhone contains components and radios that emit electromagnetic 

fields. iPhone also contains magnets and the included headphones also have magnets in the 
earbuds. These electromagnetic fields and magnets may interfere with pacemakers, defibrillators, 
or other medical devices. Maintain a safe distance of separation between your medical device 
and iPhone and the earbuds. Consult your physician and medical device manufacturer for 
information specific to your medical device. If you suspect iPhone is interfering with your 
pacemaker or any other medical device, stop using iPhone.

Not a medical device 

iPhone and the Health app are not designed or intended for use in the 

diagnosis of disease or other conditions, or in the cure, mitigation, treatment, or prevention 
of disease.

Medical conditions  

If you have any 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.

Repetitive motion  

When you perform repetitive activities such as typing or playing games on 

iPhone, you may experience 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.
