For Your Safety
Avoiding hearing damage
Permanent hearing loss may occur if you use your
phone and/or headset at a 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:
] Limit the amount of time you use your phone and/or
headset 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.
For information about how to set a maximum volume
limit on your phone, see the features guide for your
phone.
Using your phone safely
Use of your phone while operating a vehicle is not
recommended and is illegal in some areas. Be careful
and attentive while driving. Stop using your phone if
you find it disruptive or distracting while operating any
type of vehicle or performing any other activity that
requires your full attention.
