Cleaning Your MacBook Pro Display
To clean your MacBook Pro screen, do the following:
 Shut down your MacBook Pro, unplug the power adapter, and remove the battery.
 Dampen a clean, soft, lint-free cloth or paper with water only and wipe the screen.
Do not spray liquid directly on the screen.
Avoiding Hearing Damage
Warning: 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.
