Hearing loss Listening to sound at high volumes may damage your hearing. To prevent possible hearing damage, do not listen at high volume levels for long periods. Background noise, as well as continued exposure to high volume levels, can make sounds seem quieter than they actually are. The Apple Earphones with Remote and Mic sold with iPhone 4S and later in China (identifiable by dark insulating rings on the plug) are designed to comply with Chinese standards and are not compatible with iPod shuffle. Use only compatible earbuds or headphones 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 shuffle, see Setting a volume limit on page 20.

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 shuffle is designed, tested, and manufactured to comply with regulations governing radio frequency emissions, such emissions from iPod shuffle can negatively affect the operation of other electronic equipment, causing them to malfunction. Turn off iPod shuffle when use is prohibited, such as while traveling in aircraft, or when asked to do so by authorities.

Medical conditions If you have medical conditions that you believe could be affected by iPod shuffle (for example, seizures, blackouts, eyestrain, or headaches), consult with your physician prior to using iPod shuffle.

Important handling information

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, then make sure that the connector matches the port and that the connector is positioned correctly in relation to the port.

Operating iPod shuffle in acceptable temperatures iPod shuffle is designed to work in temperatures between 0º and 35º C (32º and 95º F) and stored in temperatures between -20º and 45º C (-4º and 113º F). iPod shuffle can be damaged and battery life shortened if stored or operated outside of this temperature range (for example, if left in a hot car). iPod shuffle will shut down if it gets too hot. Avoid exposing iPod shuffle to dramatic changes in temperature or humidity. When you’re using iPod shuffle or charging the battery, it is normal for iPod shuffle to get warm.

Keeping the outside of iPod shuffle clean To clean iPod shuffle, unplug all cables, turn it off (slide the three-way switch to OFF), and use a soft, slightly damp, lint-free cloth. Avoid getting moisture in openings. Don’t use window cleaners, household cleaners, aerosol sprays, solvents, alcohol, ammonia, or abrasives to clean iPod shuffle.

Disposing of iPod shuffle properly For information about the proper disposal of iPod shuffle, including other important regulatory compliance information, see Disposal and Recycling Information on page 31.
