(170-1168)                 Operation II               Faxback Doc. # 39249

Selecting The Phone Number

If you subscribe to two cellular services (for example, on competitive
cellular systems in your area or on cellular systems in different cities),
your dealer programs you phone with two different telephone numbers.  Each
number is stored in a NAM (Number Assignment Module).

The NAM SELECT function lets you select which phone number to use
(if two have been programmed).

1.  Press MNU 7.

2.  The phone displays the number currently in use.
    Press /\ or \/ to select the other number.

3.  Press STO to confirm.

Setting The Cellular System Type

Using the phone in a city where you do not subscribe to a cellular service
is referred to as roaming.

Each cellular market area has two cellular service providers.  One of the
providers is designated Provider A and the other Provider B.  When your
phone is activated for service, find out from your dealer whether your
cellular provider is type A or B.

It is possible for the company you purchase your cellular service from to
be (or have agreements with) Provider A in some cities and Provider B in
other cities.

Usually it is less expensive to use the same company for cellular service
when you are in your home city and when you roam.  To do this you need to
know whether your cellular service provider is type A or B in your home
city and in each city you plan to travel to.

The SYSTEM SELECT function lets you select one of four possible roaming
modes:

    HOME TYPE A* or HOME TYPE B**

    Use this setting if you are roaming and your home city cellular
    service provider is the same provider type in the city you have
    traveled to (for example, if the company is Provider A in both
    cities).

    NON-HOME TYPE B* or NON-HOME TYPE A**

    Use this setting if you are roaming and your home city cellular
    service provider is the opposite provider in the city you have
    traveled to (for example, if the company is Provider A in your
    home city and Provider B in the other city).

    HOME AREA* or HOME AREA**

    Use this setting if you do not want to roam (you can only use the
    phone within the area covered by your home cellular service provider).

    BOTH SYSTEMS* or BOTH SYSTEMS**

    With this setting the phone will use either Provider A or B in the
    city you have traveled to, whichever has the stronger signal.

    *  When System A NAM is selected.

    ** When System B NAM is selected.

Note:  The home system depends on the type of the currently selected NAM.
       The phone displays the selected type (A or B) in the upper left
       corner of the display.

To select the roaming mode, set the cellular system type as follows:

1.  Press MNU 1.

2.  After a few seconds, the phone displays the system select mode
    currently in use.  Press /\ or \/ to scroll to the desired option.

3.  Press STO to confirm.

Roaming

In some areas, the cellular system's computer automatically recognizes
roaming telephones.  In other areas, you must contact the cellular company
before it can recognize your phone.  The company needs to know your
telephone number, you phone's ESN (Electronic Serial Number), and how you
intend to pay for your calls.  There is usually an additional charge for
roaming calls.

When you roam, the ROAM indicator flashes if you are using a cellular
system that is different from your home system (A or B).  The indicator
lights steadily if you roam and are using a system that is the same as
your home system (see "Setting the Cellular System Type").

Call Timers

The call timer function tracks the duration of your current/last call,
the duration of all calls (for the currently selected NAM), or resets the
timers (for both NAMs):

1.  Press MNU 3.

2.  The phone displays the duration of the last/current call
    (LAST hrs:mins:secs).

    Press \/ once to display the duration of all calls since the last call
    timers reset (TOTAL hrs:mins:secs).

    Press \/ twice to display the life time counter.  This displays the
    total of calls made since the phone was activated and cannot be reset.

    (LIFE hrs:mins:secs).

    Press \/ again (3 times) and the message RESET TIMERS appears.

3.  To reset the Last Call and Total timers, press STO.

    The phone displays SECURITY? to prompt you to enter your five-digit
    security code.  To leave the timers unchanged, press CL.

4.  Enter the five-digit security code and press STO to confirm.  If you
    enter the security code incorrectly, the phone displays CODE ERROR and
    you must enter the correct code.

5.  After you enter the correct code, the phone displays TIMERS CLEARED.
    The LIFE TIME counter does not reset.

five numbers dialed (see "Operation I," Faxback Doc. # 39247) after it

call.  It sounds a short beep and flashes the lights.

2.  Press /\ or \/ to scroll to the desired ringing volume option.

Using Touch Tone Services

To access computer services, such as bank-by-phone or voicemail, you can
either dial directly or use memory dialing (see "Operation I, Faxback Doc.
# 39247").  When you dial a number while a call is already in progress,
the phone produces a touch tone for each keypress.

Manual Tone Dialing:

1.  Call the computer service's telephone number in the usual way.

2.  When the service answers, enter any additional numbers required.
    Each number is sent immediately as a touch tone.  The tone sounds for
    as long as you press the key.

Automatic Tone Dialing:

    menu is connected, the message NONE PRESENT appears.
