Handling the Battery
Avoiding Hearing Damage
Warning: Never push objects of any kind into this product through the openings in
the case. Doing so can be dangerous and might result in fire or electric shock.
Warning: There is risk of explosion if the battery is replaced by an incorrect type.
Dispose of used batteries according to your local environmental guidelines. Don’t
puncture or incinerate the battery.
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.
