Warning: There is a risk of explosion if the battery is replaced by an incorrect battery type. Dispose of used batteries according to your local environmental guidelines. Don’t puncture or incinerate the battery.

Avoid 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, which may sound normal but can be damaging to your hearing. Set your PowerBook volume to a safe level before that happens. If you experience ringing in your ears, reduce the volume or discontinue use of earbuds or headphones with your PowerBook.
