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.
