Cellular Telephone
(170-1204/05/06)     Operation - Roaming & System     Faxback Doc. # 46527

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 provided telephone service to your community, generally referred to
as a wireless 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 operated 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 NoSvc (No Service) light will appear 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 appear in the 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.

Roaming

The term 'Roaming' applies to the use of cellular telephones within
systems other than those designed as their 'Home' system. Roam lights
whenever the unit comes within range of a visited system.  As your
telephone begins to roam, it seeks service according to the conditions
you have selected (see chart below).

Slow flashing of Roam signals that your telephone 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. # 46529. If you selected Two Telephone Number Capability (see
below), 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.

System Type Selection
(Selectable System Registration)

Your telephone seeks cellular service according to the mode you have
selected.

Standard Mode:                                              Display:

Unit first seeks a home type system, then a non-home type.

If home system is non-wireline (type A)                     Std Ab

If home system is wireless (type B)                         Std bA

Invert Preference Mode:

Unit first seeks a non-home type system. Roam acts as in
standard mode (it does not invert).

If home system is non-wireline (Type A)                     SCAn bA

If home system is wireline (type B)                         SCAn Ab

Home Only Mode:

Unit will not operate outside its home system.              HOME

Scan A Mode:

Unit will operate only within non-wireline (A) systems.     SCAn A

Scan B Mode:

Unit will operate only within wireline (B) systems.         SCAn b

Enter SID Mode:

Unit will operate only within specifically identified       PrEF'd
systems.                                                    Sids
This choice requires entry of up to 15 system ID numbers    
for those systems over which you wish to operate.
The SIDdigits are entered as obtained from your Cellular
Service Provider.

Note:  If you have selected Two Telephone Number Capability, the telephone
       seeks cellular service according to the System Type mode selected
       for each telephone number.  There are also separate SID lists for
       Two Telephone Number Capability.

Changing System Type

1.  To choose a System Type, press [RCL], [*].  The display will show the
    currently active choice.

2.  Repeatedly press [*] until the desired System Type appears in the
    display.

3.  To activate the selection, press [STO]. To return to normal operation,
    press [END].

To exit without changing selections, press [END].  You may confirm your
selection with Feature Status Review (see Faxback Doc. # 46529), or by
reentering the sequence above.  If you have chosen Two Telephone Number
Capability, the choices above will be set separately for each system.

If you choose Pref'd SIDs, continue with Step 4.

4.  The first of 15 (0-14) SIDs will appear.

5.  Enter desired five-digit SID number.

6.  Use [*] and [#] to move to the next SID selection.  (Fifteen SIDs do
    not have to be entered.  Use 4000 as a blank SID.)

7.  Press [STO].

Note:  Constant flashing of Roam, or a steadily lit NoSvc while within
       your home service area may indicate an unintentional choice has
       been made.  If this occurs, re-enter System Type Selection to see
       if the unit is operating in standard mode, or if an alternate
       selection has been made.

Optional 832/2412 Channel Operation (NAMPS)

A high-capacity cellular call technology is available in some markets.
This technology can use up to 2,412 channels in cellular systems designed
to use this capability.

To determine if your telephone is capable of 2412 Channel Operation, first
find the serial number located behind the battery and affixed to your
telephone.  On units capable of 2412 Channel Operation, '832/2412 Channel
Operation' will appear.  If your telephone is equipped with 2412 Channel
Operation, it will automatically operate on cellular systems so equipped.

Note:  Retrofitting for 2412 Channel Operation is not possible.

Your cellular carrier may offer enhanced features, such as Calling Line
Identifier, Voice Mail Status, and Short Messaging.  If your unit is
equipped with 2412 Channel Operation, these features may be available to
you.  Check with your Cellular Service Provider for more information.
These messages, when received by your unit, are stored in a special memory
and accessed through the Digital Messaging Service (DMS).

You will be informed when a successful message has been received by the
telephone via a beep (see Reminder Beep on Faxback Doc. # 46529).

To enter the DMS, press [RCL], then press and hold [RCL] again.  If no
messages are contained in the DMS, no MSGS will display.  If there are
any messages in the stack, the phone will display HH nEW, followed by
HH totAL to scroll through those features.  Check with your cellular
provider for more information.

Optional Two Telephone Number Capability (Dual NAM)

Your telephone can operate over two different home systems, if you have
made proper arrangements with your Cellular System Operator.  Both are
designated as your 'home system' but are accessed with separate telephone
numbers.

While you may switch from one system to the other, only one of the two
can be active at any given time.  Calls are placed and received through
the active system only.

Selecting Second Number

1.  To display the active telephone number, press [RCL], [#].

2.  To operate with this number, press [CLR], or to activate the other
    telephone number, press [STO].  The display will blank to confirm the
    switch and the newly activated number will appear.

Each time the telephone is turned on, it displays a message indicating
which home system type and telephone number is currently active.

The message shows the System Type and telephone number applied, as shown
below.

System Type and Phone Number                     Display

Non-wireline type with phone number 1             A1

Non-wireline type with phone number 2             A2

Wireline type with phone number 1                 b1

Wireline type with phone number 2                 b2

If a call is placed to the inactive telephone number, the caller will
receive the recorded 'Not in Service' message.

When you turn on your unit, the telephone will remember which system was
active when you turned the unit off.  That system will stay active until
you change to the other system with the sequence [RCL], [#], [STO].  You
cannot switch systems during a call.  If you enter the sequence during a
call, the unit will wait until the call is terminated and InUse is
extinguished before switching systems.

Each system (and telephone number) has its own Selectable System
Registration state that you may program (see Selectable System
Registration, above).  That is, you can select Home Only for System 1
(and telephone number 1) and Standard Mode for System 2 (and telephone
number 2).  Whenever you switch back to System 1, your telephone will
operate in Home Only Mode again.

Roam will operate based on the active system.  For example, if your active
system is A1 and you are roaming on a wireline (B) system Roam will flash.
Each system (and telephone number) has its own Cumulative and Resettable
Call Timers.  You can only display the Call Timers (and telephone number)
of the active system.

Note:  An improper selection of your telephone number and/or Selectable
       System Registration may cause you to roam onto your inactive home
       system.
