Chargers
Your battery needs no maintenance other than routine charging. The battery
should be at or near room temperature when charging.
The accessories shipped with your phone may vary by model.
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 red NO SVC (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 unit 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 green (on) indicator will flash quickly.
If this occurs, you must press Clr before the unit 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 under Step 11 for more
details.
Roaming
The term "Roaming" applies to the use of cellular telephones within systems
other than those designated as their "Home" system. Roam lights whenever
the unit comes within range of a visited system. As your phone begins to
roam, it seeks service according to the conditions you have selected (see
Faxback Doc. # 34523).
Slow flashing of Roam signals that your phone unit is accessing a home type
system, while rapid flashing indicates the unit 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.
To use alternate long distance services when roaming, be certain to dial
the appropriate area code and local number to access the alternate carrier
in the visited area. Then use the tone dialing sequence described on
Faxback Doc. # 34516, "Pause Dialing". If you selected two-system operation
(see Faxback Doc. # 34514), enter Rcl, # to verify the currently active
number. This is especially important if your two home systems have different
area codes, or if Roam is flashing within your home service area.
