Understanding How Your
Phone Operates
Your phone is basically a radio
transmitter and receiver. When
it's turned on, it receives and
transmits radio frequency (RF)
signals. When you use your
phone, the system handling
your call controls the power
level. This power can range
from 0.006 watts to 0.2 watts
in digital mode.
Maintaining Your Phone's
Peak Performance
For the best care of your phone,
only authorized personnel
should service your phone and
accessories. Faulty service may
void the warranty.
There are several simple
guidelines to operating your
phone properly and maintaining
safe, satisfactory service.
• Hold the phone with the
antenna raised, fully-
extended and over your
shoulder.
• Try not to hold, bend or
twist the phone's antenna.
• Don't use the phone if the
antenna is damaged.
• Speak directly into the
phone's receiver.
• Avoid exposing your phone
and accessories to rain or
liquid spills. If your phone
does get wet, immediately
turn the power off and
remove the battery. If it is
inoperable, call Customer
Care for service.
Availability of Various
Features/Ring Tones
Many services and features are
network dependent and may
require additional subscription
and/or usage charges. Not all
features are available for
purchase or use in all areas.
Downloadable Ring Tones may
be available at an additional
cost. Other conditions and
restrictions may apply. See your
service provider for additional
information.
Battery Standby and Talk
Time
Standby and talk times will vary
depending on phone usage
patterns and conditions. Battery
power consumption depends on
factors such as network
configuration, signal strength,
operating temperature, features
selected, frequency of calls, and
voice, data, and other
application usage patterns.
