Prolonged heat exposure  iPod touch and its power adapter (available separately) 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 or place a device or power adapter under a blanket, pillow, or your body 
when it’s plugged into a power source. It’s important to keep iPod touch and its power adapter 
in a well-ventilated area when using or charging them. Take special care if you have a physical 
condition that affects your ability to detect heat against the body.
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. Use only compatible receivers, earbuds, headphones, speakerphones, or earpieces 
with your device. Turn on the audio 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 touch, see 
 on page 56.
WARNING:  
To prevent possible hearing damage, do not listen at high volume levels for 
long periods.
Apple headsets  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 compatible 
with iPhone 4s or later, iPad 2 or later, and iPod touch 5th generation. Use only compatible 
headsets with your device.
Radio signals  iPod touch uses radio signals to connect to wireless networks. For information 
about the amount of power used to transmit these signals, and about steps you can take to 
minimize exposure, see Settings > General > About > Legal > RF Exposure.
Radio frequency interference  Observe signs and notices that prohibit or restrict the use of 
electronic devices (for example, in healthcare facilities or blasting areas). Although iPod touch 
is designed, tested, and manufactured to comply with regulations governing radio frequency 
emissions, such emissions from iPod touch can negatively affect the operation of other electronic 
equipment, causing them to malfunction. Turn off iPod touch or use Airplane Mode to turn off 
the iPod touch wireless transmitters when use is prohibited, such as while traveling in aircraft, or 
when asked to do so by authorities.
Medical devices  iPod touch contains radios that emit electromagnetic fields, and contains 
magnets near the bottom. The included headphones also have magnets in the earbuds. These 
electromagnetic fields and magnets may interfere with pacemakers, defibrillators, or other 
medical devices. Maintain at least 6 inches (approximately 15 cm) of separation between your 
pacemaker or defibrillator and iPod touch or the earbuds. If you suspect iPod touch is interfering 
with your pacemaker or any other medical device, stop using iPod touch and consult your 
physician for information specific to your medical device.
Medical conditions  If you have any other medical condition that you believe could be affected 
by iPod touch (for example, seizures, blackouts, eyestrain, or headaches), consult with your 
physician prior to using iPod touch. 
Explosive atmospheres  Do not charge or use iPod touch 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.
