The Cellular System

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 telephone 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 black N N o o S S v v c c (No
Service) lights 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 phone may act as if it were
beyond range.

Weak Signal Alert

If you are called while in a location the system
determines is inadequate for high quality service,
you may hear a series of beeps to inform you of
the call attempt. The caller will receive the
recorded "not in service" message, Call will
display, and the black on indicator will flash
quickly. If this occurs, you must press C before
the phone will operate. Most systems do not
impose air-time charges for such call attempts.

Switchhook and Enhanced
System Services
Press S.
During a call, pressing S performs a switchhook
function used to access enhanced Cellular System
features, such as call waiting and conference
calls. For the functioning of these features with
S, consult your Cellular Service Provider.

Roaming

The term Roaming applies to the use of cellular
telephones within systems other than those
designated as their Home system. R R o o a a m m lights
whenever the phone comes within range of a
visited system. As your phone begins to roam, it
seeks service according to the conditions you
have selected. See "System Type Selection" on
page 59.
Steady illumination of Roam signals that your
phone is accessing a home type system, while
flashing indicates the phone is attempting
connection through a non-home type system.
Contact your system operator, or that of the visited
system, for information on dialing and billing
procedures.
