Prolonged heat exposure iPod nano 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 iPod nano and its power adapter in a well-ventilated
area when in use or charging. Take special care if you have a physical condition that affects your
ability to detect heat against the body.
WARNING:
To prevent possible hearing damage, do not listen at high volume levels for
long periods.
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
. For information about how
to set a maximum volume limit on iPod nano, see
Setting the maximum volume limit
on page 25.
To avoid hearing damage, use only compatible receivers, earbuds, headphones, speakerphones,
or earpieces with your iPod nano.
The headsets sold with iPhone 4s or later in China (identifiable by dark insulating rings on the
plug) are designed to comply with Chinese standards and are only compatible with iPhone 4s or
later, iPad 2 or later, and iPod touch 5th generation.
Radio frequency exposure iPod Nano has been tested and meets applicable limits for radio
frequency (RF) exposure.
Specific Absorption Rate (SAR) refers to the rate at which the body absorbs RF energy. The SAR
limit is 1.6 watts per kilogram in countries that set the limit averaged over 1 gram of tissue and
2.0 watts per kilogram in countries that set the limit averaged over 10 grams of tissue. During
testing, iPod radios are set to their highest transmission levels and placed in positions that
simulate use against the body. Cases with metal parts may change the RF performance of the
device, including its compliance with RF exposure guidelines, in a manner that has not been
tested or certified.
Radio frequency interference Observe signs and notices that prohibit or restrict the use of
electronic devices (for example, in health care facilities or blasting areas). Although iPod nano
is designed, tested, and manufactured to comply with regulations governing radio frequency
emissions, such emissions from iPod nano can negatively affect the operation of other electronic
equipment, causing them to malfunction. Turn off iPod nano or turn off Bluetooth when use is
prohibited, such as while traveling in aircraft, or when asked to do so by authorities.
Medical device interference iPod nano contains components and radios that emit
electromagnetic fields. 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 iPod
nano and the earbuds. Consult your physician and medical device manufacturer for information
specific to your medical device. If you suspect iPod nano is interfering with your pacemaker or
any other medical device, stop using iPod nano.
Medical conditions If you have any medical condition that you believe could be affected by
iPod nano (for example, seizures, blackouts, eyestrain, or headaches), consult with your physician
prior to using iPod nano.
