Water and wet locations Keep your MacBook away from sources of liquid, such as

drinks, washbasins, bathtubs, shower stalls, and so on. Protect your MacBook from

dampness or wet weather, such as rain, snow, and fog.

60W MagSafe Power Adapter Make sure the AC plug or AC power cord is fully

inserted into the power adapter before plugging the adapter into a power outlet. Use

only the power adapter that came with your MacBook, or an Apple-authorized power

adapter that is compatible with this product. The power adapter may become very

warm during normal use. Always put the power adapter directly into a power outlet, or

place it on the floor in a well-ventilated location.

Disconnect the power adapter and disconnect any other cables if any of the following

conditions exist:

 You want to add memory or upgrade the hard disk drive.

 You want to clean the case (use only the recommended procedure described on

page 73).

 The power cord or plug becomes frayed or otherwise damaged.

 Your MacBook or power adapter is exposed to rain, excessive moisture, or liquid

spilled into the case.

 Your MacBook or power adapter has been dropped, the case has been damaged,

or you suspect that service or repair is required.

The MagSafe power port contains a magnet that can erase data on a credit card, iPod,

or other device. To preserve your data, do not place these or other magnetically

sensitive material or devices within 1 inch (25 mm) of this port.

If debris gets into the MagSafe power port, remove it gently with a dry cotton swab.

Hearing damage Permanent hearing loss may occur if earbuds or headphones are

used at high volume. 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:

 Limit the amount of time you use earbuds or headphones at high volume.

 Avoid turning up the volume to block out noisy surroundings.

 Turn the volume down if you can’t hear people speaking near you.
