SafetyTips
Consider device compatibility
If you have a pacemaker or hearing aid, check
with your doctor to make sure it is safe for you to
use a cell phone. In some cases, cellular radio
frequencies can disrupt the performance of other
electronic equipment. If you have questions about
the interaction between your phone and any other
piece of electronic equipment, ask the equipment
manufacturer.
Drive safely
When you are driving, T-Mobile encourages you to
use your phone in a safe and sensible manner. Here
are a few tips:
•Assess road conditions before answering your
phone. Your safety is more important than any
call.
•Prepare your hands-free headset, if you have one,
or turn on your speakerphone, before you
start moving.
•Keep your phone close. If it rings and you
discover it’s in the back seat, do NOT crawl over
the seat to answer it while driving.

16
•Pre-program frequently used numbers into your
phone for easy, one-touch dialing.
•Remember that laws prohibiting or restricting the
use of a cell phone while driving may apply in
your area.
Information About
Safeguarding Handsets
T-Mobile encourages customers to take appropriate
measures to secure their handsets and invites
them to take advantage of the features available
on this handset to help secure it from theft and/or
other unauthorized access and use. This handset
has a locking function (e.g., user-defined codes or
patterns) that can serve as a first line of defense
against unauthorized use or access to stored
information. Preloaded security applications that
allow customers to track or locate misplaced
devices can be found on several T-Mobile devices.
Lost or stolen devices should be immediately
reported to T-Mobile so that proper measures can
be taken to protect accounts.

CaringForYour Phone
Your phone is a complex electronic device; think of
it as a mini-computer. Here are some tips to help you
extend the life of your new device:
Do not get your device wet.
Water will damage your
phone and accessories. Even a small amount of
moisture can cause damage.
Protect your phone’s touch screen.
Your phone’s
touch screen is delicate. Guard against scratches
by using a screen protector or by keeping it in a
protective case.
Use the original manufacturer’s batteries and
accessories.
Non-approved batteries and
accessories can harm you and damage your phone.

Do not use damaged accessories.
Do not attempt
to charge your phone if the charger has received
a sharp blow, been dropped, or is otherwise

it or take it to a qualified service dealer.
