USING THE MESSAGING FUNCTIONS

Some cellular systems provide services that can send calling line ID and
voice mail notification to your phone.  Your phone is preprogrammed to
work with these services.

Note:  In order to use these functions on your phone, your cellular
       carrier must provide, and you must subscribe to, these services.
       Otherwise, selecting or setting them will have no effect.  For more
       information about these services, call your cellular carrier.

Overview/Receiving Messages

When your phone is turned on and receives calling line ID or voice mail
notification data from your cellular carrier, it alternately displays:

You See     Meaning

XX nEW      Number (xx) of new messages received

YY totAL    Total number (YY) of messages currently stored in the message
            stack

Your phone stores each message in a special memory area called the
"message stack."  The message stack can hold up to 20 messages at once,
with messages stored in order from newest (memory position 1) to oldest
(memory position 20).

Notes:  If the message stack is full (20 messages are currently stored)
        and the phone receives a new message, it automatically stores the
        new message and deletes the oldest message in the stack.

        Your phone does not receive messages while it is turned off.
        Contact your cellular carrier to find out how the carrier handles
        undeliverable/queued messages.

Viewing/Recalling Messages

Follow these steps to view or recall a message.

1.  Press and release [RCL], then hold it down for about 1 second.  The
    phone displays the first (newest) message in the stack.

    If the message is a calling line ID message, the phone briefly
    displays cId yy (where yy is the message number) then the number of
    the party that called (up to 14 characters).

    If the message is voice mail notification, the phone displays the
    message data (such as a message number and/or number of total/new
    messages waiting) sent by your cellular carrier.  The type and format
    of the message waiting information sent varies by carrier - contact
    your cellular carrier for more information.

    Note:  If there are no messages in the stack, the phone displays
           noMSgS for about 8 seconds then exits the message display.  To
           exit sooner, press [CLR].

2.  To view another message, repeatedly press [< *] (to scroll backwards)
    or [# >] (to scroll forwards) until that message appears.

3.  When you finish, press [END] to exit the message function.

Deleting Messages

To delete an individual message, recall that message, then hold down [CLR]
until the phone displays dELEtEd.

To delete all messages in the stack, while viewing any message, hold down
[CLR] until the phone displays dELEtEd (briefly) then ErASE ALL.  Then
press [CLR] again to confirm the deletion.

When you finish, press [END] to exit the message function.

USING THE CALL TIMERS

Your phone has three call timers that let you check the length of your
calls ("air time"):

                  Individual call timer - times each call you make or
                                          answer in minutes and seconds,
                                          and automatically resets each
                                          time you make or answer a call
                                          or turn off the phone.  See
                                          "Displaying the Individual Call
                                          Timer" below.

                  Resettable call timer - times all the calls you make or
                                          answer in minutes, and it can be
                                          reset at any time.  See "Using
                                          the Resettable Call timer"
                                          below.

                  Cumulative call timer - times the calls you make or
                                          answer in minutes, and it cannot
                                          be reset.  See "Displaying the
                                          Cumulative Call Timer" below.

Notes:  Each call timer begins counting when you hear the first ring
        (during an outgoing call) or when your phone rings to signal an
        incoming call.

        If your phone receives a call but you do not answer it, each timer
        resets to the time it had before it received that incoming call.

Displaying the Individual Call timer

The individual call timer tracks each call you make in minutes and
seconds, and automatically resets each time you make or answer a call or
when you turn off the phone.

To display the individual call timer for the last call, press [RCL][# >]
[# >].  The air time of your last call (such as 00 45 to show 45 seconds)
appears for about 15 seconds.  Press any key to clear the display sooner.

If you press [RCL][# >][# >] during a call, the air time of the call
flashes on the display until you clear the display or end the call.

Using the Resettable Call Timer

The resettable call timer tracks the calls you make or answer in minutes,
and it can be reset at any time.  You can reset this timer to coincide
with your cellular billing statement date, for example, then track your
monthly air time.

To display the resettable call timer, press [RCL][# >][# >][# >].  RESEtbL
(resettable) and the number of air time minutes accumulated since you last
reset the timer appear.

To reset the timer while it is displayed, press [FCN][OPER 0][PRS 7][CLR].

To clear the timer from the display, press any key other than [# >].

Displaying the Cumulative Call Timer

The cumulative call timer tracks all the calls you make or answer in
minutes.  It cannot be reset.

To display the cumulative call timer, press [RCL], [# >][# >][# >][# >].
CUMUL and the number of air time minutes accumulated since the first call
was made or answered on your phone appears.  Press any key to clear the
timer from the display.

SELECTING THE ACTIVE PHONE NUMBER

If you subscribe to two cellular services (for example, competitive
cellular systems in your area or cellular systems in different cities),
your dealer programs your phone with two different phone numbers.

If you have two phone numbers programmed into your phone, the phone
displays one of the following messages each time you turn it on, to
indicate which cellular system type and phone number are currently active.

Phone Number       Cellular System Type     Display Shows

    1              Non wireline (type A)           A1

    2              Non-wireline (type A)           A2

    1              Wireline (type B)               b1

    2              Wireline (type B)               b2

Note:  To set the cellular system type, see "Selecting the Cellular system
       Type" below.

To deactivate the phone number currently selected and activate the other
phone number, press [RCL][# >][STO].  The display briefly blanks, then the
currently active number appears to confirm your selection.  To clear the
display when you finish, press [CLR].

Notes:  Calls can be made on your phone from only one phone number at a
        time, and you cannot activate the other phone number while a call
        is in progress.

        To receive calls on both numbers at the same time (if you
        subscribe to no-answer transfer or call forwarding service through
        your cellular carrier), you can set both numbers to forward to the
        other number if not answered.  Otherwise, a caller who calls the
        inactive number receives the standard "not in service" message.

SETTING THE CELLULAR SYSTEM TYPE

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.

Notes:  Usually, it is less expensive to use the same company for cellular
        service when you are in your home city and when you roam (see
        "Roaming" below).  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 where you plan to travel.

        It is possible for a cellular service provider to be (or have
        agreements with) Provider A in some cities and Provider B in
        others.

Your phone's selectable system registration function lets you select one
of seven possible roaming modes:

Roaming Mode Description                                           Display

Standard Mode - the phone first seeks a home type system,
                then it seeks a non-home type.

If you are using a type A (non-wireline) home system                Std Ab

If you are using a type B (wireline) home system                    Std bA

Invert Preference Mode - the phone first seeks a non-home type
                         system, then it seeks a home type.
                         (Select this setting while on the fringe
                         of your home area or in certain roaming
                         situations.)

If your home system is non-wireline (type A):                      SCAn bA

  RM flashes rapidly - call on system B

  RM flashes slowly - call on home type system

  IU flashes slowly - call on home system

If your home system is wireline (type B):                          SCAn Ab

  RM flashes rapidly - call on system A

  RM flashes slowly - call on home type system

  IU flashes slowly - call on home system

Home Only Mode - the phone will not operate                           HOME
                 outside your home system.

Scan A Mode - the phone will operate only within                    SCAn A
              wireline (B) systems.

Scan B Mode - the phone will operate only within                    SCAn b
              wireline (B) systems.

SID Mode - the phone automatically scans for one or more            P SCAn
           preferred systems to use and one or more systems
           not to use.  System IDs must be preprogrammed by
           dealer; preferred system (SID) feature requires
           special service (contact your cellular carrier).

Displaying The Currently Selected System Type

To display the system type currently selected on your phone, press [RCL]
[< *].  The currently selected system type (such as HOME) appears for
about 8 seconds.  To clear the display sooner, press [END].

Selecting the Cellular System Type

Note:  If you are unable to complete Steps 2 and 3 within 8 seconds, the
       display clears without changing the system type.  Start at Step 1
       and try again.

1.  Press [RCL][< *].  The currently selected system type appears.

2.  Repeatedly press [< *] or [# >] until you see the system type you want
    to use.

3.  Press [STO] to store the displayed system type.  SEt appears to
    confirm the change.

    To exit without changing the system type, press [END].

ROAMING

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

Note:  Your phone's ESN is under the phone's battery; however, the roaming
       cellular service provider can usually automatically determine your
       phone's ESN when you call.

When you roam, RM flashes slowly on the display when the phone is using a
home-type cellular system.  The indicator flashes rapidly when the phone
is using a cellular system that is different from your home system.

USING CELLULAR SYSTEM PIN DIALING

Your cellular carrier might require that you use a personal identification
number (PIN) when you make calls.  This number assures the cellular system
that the person placing the call is an authorized user.

Contact your cellular service provider to determine if a PIN is required
and obtain the PIN (seven digits or less) to place calls through the
cellular system you subscribe to.  If a PIN is required, follow the steps
in "Storing Speed Dial Numbers" in Faxback Doc. # 47922 to store your PIN
in memory 07, then follow the steps in "Enabling/Disabling PIN Dialing"
below to enable PIN dialing on your phone.

Notes:  Enable PIN dialing on your phone only if it is required by your
        cellular provider.

        You must store your PIN in memory 07, otherwise your phone cannot
        properly make calls through your cellular system.

        If you enter a service area which does not require PIN dialing,
        disable PIN dialing on your phone.

Enabling/Disabling PIN Dialing

1.  Press [FCN][1].

2.  Repeatedly press [< *] or [# >] until the phone displays Pin inActiv
    or ActivE.

3.  Press [STO] so ActivE appears (to enable) or [CLR] so inActiv appears
    (to disable).

4.  To exit the function menu, press [END].

Making a Call Using Your PIN

1.  With PIN dialing enabled, dial or speed dial the number you want to
    call, as usual, then press [SND].

2.  When you hear the tones (2 beeps), press [SND] again.  The phone
    automatically sends your PIN code to finish dialing the call.

Note:  If you did not store your PIN in memory 07, or you stored an
       incorrect PIN, invALid Pin appears.  Be sure your PIN is correct,
       then try again.

USING THE PHONE WITH HANDSFREE EQUIPMENT

Your phone is preprogrammed to work with most optional handsfree equipment
in your vehicle that lets you automatically switch from handset to
handsfree mode when you place the phone in the handsfree holder.

Some handsfree equipment might require you to turn off (mute) the phone's
microphone when switching to handsfree, using the procedure described in
"Using Mute" in Faxback Doc. #47919.  See the owner's manual provided with
your handsfree equipment for more information, or contact your local
RadioShack store for assistance.

USING A HEADSET

You can make or answer calls with handsfree convenience using an optional
headset that has a 3/32-inch (2.5 mm) plug.  We recommend RadioShack Cat.
No. 43-194.

To connect the headset, insert the headset's plug into the headset jack on
the side of the phone.

With a headset connected, you make calls as usual.  You can answer a call
simply by pressing any number key [0-9], [SND], or [VOL].

Notes:  The headset's earpiece and microphone must be used when the
        headset is connected.  Connecting a headset disconnects the
        phone's earpiece and microphone.

        You can connect or disconnect the headset without affecting a call
        in progress.

        [VOL] also controls the connected headset's volume (see "Adjusting
        the Volume" in Faxback Doc. # 47919).

USING TOUCH-TONE SERVICES

To use your cellular phone to control answering machines and special
telephone services (such as bank-by-phone or voicemail), simply enter
touch-tone commands using your phone's keypad after the service answers
(and when prompted).

Or, you can store the service's command sequence in a memory location,
then follow these steps after the service answers (for each sequence you
want to send).

1.  Recall the memory location that contains the command sequence.

2.  Press [RCL] [SND].

Adding a Pause

Some services, such as voicemail, require you to enter an access code then
wait before entering additional digits.  To include one or more pauses in
a sequence when storing it in memory, press [FCN] [SND] so 0 appears, then
press [STO].  The phone displays O wherever you insert a pause.

Note:  If you do not press [STO] within 8 seconds, the display clears to
       conserve battery power.  If this happens, simply press the key for
       the next digit you want to enter or store.  The characters you
       previously entered appear along with the pause you just entered.

When you send a sequence with pauses stored in it, the phone stops at each
place in the sequence where you entered a pause.  To send the next group
of numbers in the sequence, press [SND] again.
