Before You Start
Safety Instructions
WARNING! To reduce the possibility of electric shock,
do not expose your phone to high humidity areas, such
as the bathroom, swimming pool, etc.
Always store your phone away from heat. Never store
your phone in settings that may expose it to
temperatures less than 32°F or greater than 104°F,
such as outside during extreme weather conditions or
in your car on a hot day. Exposure to excessive cold or
heat will result in malfunction, damage and/or
catastrophic failure.
Be careful when using your phone near other
electronic devices. RF emissions from your mobile
phone may affect nearby in adequately shielded
electronic equipment. You should consult with
manufacturers of any personal medical devices such
as pacemakers and hearing aides to determine if they
are susceptible to interference from your mobile
phone. Turn off your phone in a medical facility or at a
gas station. Never place your phone in a microwave
oven as this will cause the battery to explode.
IMPORTANT! Please read the TIA SAFETY
INFORMATION on page 85 before using your phone.

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.
