you better reception.
Understanding the Power Save Feature
If your phone is unable to find a signal after 15 minutes of
searching, a Power Save feature is automatically
activated. If your phone is active, it periodically rechecks
service availability or you can check it yourself by
pressing any key.
Anytime the Power Save feature is activated, a message
displays on the screen. When a signal is found, your
phone returns to standby mode.
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.
•
If your phone is equipped with an external antenna, hold the
phone with the antenna raised, fully-extended and over your
shoulder.
•
Do not hold, bend or twist the phone's antenna.
