Cellular System Information
Cellular System Overview
There are generally two types of cellular systems serving
any metropolitan area. One of these will most likely be
operated by the telephone company that provides
telephone service to your community, generally referred to
as a wireline carrier. The other cellular service provider is a
radio common carrier, referred to as a non-wireline carrier.
Your Cellular Service Operator will provide information
concerning specific features, procedures, and coverage in
your particular area.
Service Area
The area within which the phone operates is defined by
your cellular service provider. Since this is a radio system,
no exact boundaries (as on a map) can be drawn. The red

NS

(No Service) flashes if you are beyond range of a
service area. There may be locations within your area, such
as tunnels and underground parking facilities, where the
unit may act as if it were beyond range.
Weak Signal Alert
If you are called in a location the system determines is
inadequate for high quality service, you may hear series of
beeps to inform you of the call attempt. The caller will
receive the recorded “Not In Service” message.
CALL
will
appear in the display, and the green on indicator will flash
quickly. If this occurs, you must press before the
phone will operate. Most systems do not impose air-time
charges for such call attempts.
NOTE This indicator is controlled through the initial
programming of your phone. Refer to the Programming
Guide for more details.
