Apple iPhone 4 - Manual (Page 5)

contained in the iPhone earbuds. Never rely solely on the digital
compass for determining direction. Compare the information provided
on iPhone to your surroundings and defer to posted signs to resolve
any discrepancies.
Do not use location-based applications while performing activities that
require your full attention. Always comply with posted signs and the laws
and regulations in the areas where you are using iPhone.
For Vehicles Equipped with an Air Bag An air bag inflates with great
force. Do not store iPhone or any of its accessories in the area over the air
bag or in the air bag deployment area.
Seizures, Blackouts, and Eyestrain A small percentage of people may
be susceptible to blackouts or seizures (even if they have never had one
before) when exposed to flashing lights or light patterns such as when
playing games or watching video. If you have experienced seizures
or blackouts or have a family history of such occurrences, you should
consult a physician before playing games (if available) or watching videos
on your iPhone. Discontinue use of iPhone and consult a physician if
you experience headaches, blackouts, seizures, convulsion, eye or muscle
twitching, loss of awareness, involuntary movement, or disorientation.
To reduce risk of headaches, blackouts, seizures, and eyestrain, avoid
prolonged use, hold iPhone further away from your eyes, use iPhone in a
well-lit room, and take frequent breaks.
Choking Hazards iPhone and its accessories may contain small parts,
which may present a choking hazard to small children. Keep such parts
away from small children.
Repetitive Motion When you perform repetitive activities such as
typing or playing games on iPhone, you may experience occasional
discomfort in your hands, arms, shoulders, neck, or other parts of your
body. Take frequent breaks and if you have discomfort during or after
such use, stop use and see a physician.
Potentially Explosive Atmospheres Turn off iPhone when in any area
with a potentially explosive atmosphere. Do not charge iPhone, and obey
all signs and instructions. Sparks in such areas could cause an explosion
or fire, resulting in serious injury or even death.
Areas with a potentially explosive atmosphere are often, but not always,
marked clearly. Potential areas may include: fueling areas (such as gas
stations); below deck on boats; fuel or chemical transfer or storage
facilities; vehicles using liquefied petroleum gas (such as propane or
butane); areas where the air contains chemicals or particles (such as grain,
dust, or metal powders); and any other area where you would normally be
advised to turn off your vehicle engine.
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.
Accessories and Wireless Performance Not all iPod accessories are
fully compatible with iPhone. Turning on Airplane Mode on iPhone may
eliminate audio interference between iPhone and an accessory. While
