Signal strength indication
A cellular phone sends and receives radio signals.
As with all radio equipment, the quality of radio
reception depends on the strength of the radio
signal in the area where you are operating your
phone.
The strength of the cellular signal is
shown by the vertical bar on the left-
hand side of the display. The higher the
bar, the stronger the signal at your
present location, and the more likely you
are to get good call quality.
When NO SERVICE is displayed, the
phone is either outside of the cellular
service area or restricted from entering service,
and calls cannot be made or received.
If the signal is poor and you are using the phone
in a building, you may get better reception near a
window.
IMPORTANT! The phone can make and receive calls
only when:
• It is switched on, and
• It is located in the cellular service area, and
the radio signal strength is adequate.
To make an emergency call, see "Emergency Calls"
on page 75.
