Getting the Most Out of Your Signal Reception
The quality of each call you make or receive depends on the 
signal strength in your area. Your phone informs you of the 
current signal strength by displaying a number of bars next to the 
signal strength icon. The more bars displayed, the stronger the 
signal.
If you're inside a building, being near a window may give 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, if applicable.
• 
Do not use the phone if the antenna is damaged.
• 
If your phone is equipped with an internal antenna, obstructing the 
internal antenna could inhibit call performance.
• 
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.
