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 www.apple.com/sound. For information about how to set a maximum volume limit on iPod touch, see Music settings 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.
