Avoiding hearing damage Permanent hearing loss may occur if the earbuds or
headphones 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 mued speech, stop listening
and have your hearing checked. The louder the volume, the less time is required before
your hearing could be aected. Hearing experts suggest that to protect your hearing:
Limit the amount of time you use earbuds or headphones 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 iPod nano, see “Setting
the Maximum Volume Limit” on page 30.
Driving and riding safely Use of iPod nano alone, or with headphones (even if used
in only one ear) while operating a vehicle or riding a bicycle is not recommended and
is illegal in some areas. Check and obey the laws and regulations on the use of mobile
devices like iPod nano in areas where you drive or ride. Be careful and attentive while
driving or riding a bicycle. Stop using iPod nano if you nd it disruptive or distracting
while operating any type of vehicle, or performing any other activity that requires your
full attention.
Seizures, blackouts, and eye strain A small percentage of people may be susceptible
to blackouts or seizures (even if they have never had one before) when exposed to
ashing 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,
please consult a physician before playing games (if available) or watching videos on
your iPod nano. Discontinue use and consult a physician if you experience: headaches,
blackouts, seizures, convulsion, eye or muscle twitching, loss of awareness, involuntary
movements, or disorientation. To reduce risk of headaches, blackouts, seizures, and
eyestrain, avoid prolonged use, hold iPod nano some distance from your eyes, use
iPod nano in a well lit room, and take frequent breaks.
Repetitive motion When you perform repetitive activities on iPod nano, 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.
