Using the iPod USB Power Adapter (available separately) If you use the iPod USB Power Adapter (sold separately at www.apple.com/ipodstore) to charge iPod nano, make sure that the power adapter is fully assembled before you plug it into a power outlet. Then insert the iPod USB Power Adapter firmly into the power outlet. Do not connect or disconnect the iPod USB Power Adapter with wet hands. Do not use any power adapter other than an Apple iPod power adapter to charge your iPod nano. The iPod USB Power Adapter may become warm during normal use. Always allow adequate ventilation around the iPod USB Power Adapter and use care when handling. Unplug the iPod USB Power Adapter if any of the following conditions exist: Â The power cord or plug has become frayed or damaged. Â The adapter is exposed to rain, liquids, or excessive moisture. Â The adapter case has become damaged. Â You suspect the adapter needs service or repair. Â You want to clean the adapter. Avoiding hearing damage Permanent hearing loss may occur if 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 muffled speech, stop listening and have your hearing checked. The louder the volume, the less time is required before your hearing could be affected. Hearing experts suggest that to protect your hearing: Â Limit the amount of time you use earbuds or headphones at high volume. Â Avoid turning up the volume to block out noisy surroundings. Â 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 26. Using headphones safely Use of headphones while operating a vehicle is not recommended and is illegal in some areas. Be careful and attentive while driving. Stop using iPod nano if you find it disruptive or distracting while operating any type of vehicle or performing any other activity that requires your full attention. Use caution when using iPod headphones with lanyards (sold separately at www.apple.com/ipodstore). Certain activities may pose a risk of injury, especially if the lanyard becomes caught or trapped. 52 Chapter 6 Safety and Cleaning
