Motorola DPC-550  (170-1059)         Features          Faxback Doc. # 15576

The cellular phone contains a special memory which retains information
about the phone's individual characteristics, such as its assigned
telephone number, system identification number, and other information that
is necessary for cellular operation.  This special memory is known as the
Number Assignment Module (NAM).  You can program the phone yourself, if the
phone has not already been programmed where you purchased it.  You can also
reprogram the phone yourself should you wish to change some of the features
already selected for the NAM.

The programming of the NAM is performed after you have contacted the
cellular system operator (or operators) for the necessary information as
described below.  Enter the information received from the cellular system
operator in the NAM Programming Data Table (Faxback Doc. # 9583) before
programming the NAM of the cellular telephone.  Follow the system
operator's instructions regarding each NAM information entry.  Incorrect
NAM entries can cause the cellular telephone to operate improperly or not
at all.

The cellular telephone number can be programmed up to fifteen times.  After
that, it must be reset at a Motorola -- authorized service facility.

FEATURES TO BE PROGRAMMED

You must request seven pieces of information from the cellular system
operator to allow you to program the cellular phone.  You provide the
remaining information.  Write all of this programming information down for
future reference before commencing the procedure.  Incorrect NAM entries
can cause the cellular telephone to operate improperly or not at all.  The
required information is:

 System Identification (SID) Code - Indicates your Home system.  Enter
 (5 digits)                         0's into the left-most unused
                                    positions.  Provided by the system
                                    operator.

        Cellular Telephone Number - Used in the same manner as a standard
        (10 digits)                 land-line telephone.  The mobile phone
                                    number and the Electronic Serial Number
                                    are checked against each other by the
                                    cellular system each time a call is
                                    placed or received.  Provided by the
                                    system operator.

    Station Class Code (2-digits) - 06 or 14 for Digital Personal
                                    Communicator or portable telephones.
                                    Even though the phone has extended
                                    bandwidth capability (832 channel
                                    capacity), the cellular system operator
                                    may require the station class code to
                                    remain 06.  The code should be 14 if
                                    832 channel operation is allowed.  (If
                                    you have the Extended System, and wish
                                    it to be programmed with a separate
                                    phone number for standalone operation,
                                    the class code mark will be set to 12
                                    for the Extended System--with the
                                    Digital Personal Communicator telephone
                                    disconnected).  Provided by system
                                    operator.

       Access Overload (2-digits) - Provided by the system operator.

         Group ID Mark (2-digits) - Provided by system operator.

         Security Code (6-digits) - The six-digit security code allows the
                                    user to restrict his calls in certain
                                    ways and it permits other advanced
                                    security measures.  Select any 6-digit
                                    code that you will remember, but one
                                    that will not be easily compromised.

           Unlock Code (3-digits) - The 3-digit unlock code unlocks the
                                    telephone after it has been locked.
                                    Locking the telephone allows you to
                                    prevent unauthorized usage.  With many
                                    models, this number can be programmed
                                    as often as desired.  Select any
                                    convenient 3-digit number.

Initial Paging Channel (4-digits) - Use a leading zero if required.
                                    (Example:  Channel 334 is entered as
                                    0334).  Provided by the system
                                    operator.

           Option Bits (6-digits) - This programming step allows you to
                                    program six separate features in one
                                    step.  Each feature is either selected
                                    or cancelled by assigning a value of 1
                                    or 0.  The six individual single-digit
                                    features combine to form a six-digit
                                    code which is entered as one step.  If
                                    any of the features is to be changed,
                                    the entire six-bit word must be
                                    reentered.

                 Internal Speaker - This feature is normally selected by
                                    programming 0.  However, if you
                                    purchased the Convertible Accessory
                                    and it contains a separate External
                                    Speaker/VSP unit, cancel the internal
                                    speaker feature by programming 1.

                        Local Use - This feature is normally selected by
                                    programming 1.  Your system operator
                                    can tell you if you need to cancel
                                    this feature by programming 0.

                         MIN Mark - This feature is normally not used and
                                    is assigned a value of 0.

                      Auto Recall - This feature is always set at 1.

              Second Phone Number - This feature is normally selected by
                                    programming 1.  Enter a 1 only if you
                                    wish to enter a second telephone number
                                    and the telephone is equipped for a
                                    dual system operation.

                       Future Use - This feature is always set at 0.

                      Option Bits - This programming step allows you to
                                    program an additional five separate
                                    features in one step.  Each feature
                                    is either selected or cancelled with
                                    the digit 1 or 0.  The five individual
                                    single-digit features combine to form a
                                    five-digit code which entered as one
                                    step.  If any of the features is to be
                                    changed, the entire five-digit code
                                    must be reentered.

       Failed Page Indicator
       (available in some models) - This feature if activated (1) will
                                    alert you with a series of short beeps
                                    and "CALL" will appear in the display,
                                    if an incoming call could not be
                                    completed due to insufficient signal
                                    strength.

       Motorola Enhanced Scan
       (available in some models) - This feature is always set to 1.

                   Long Tone DTMF - Certain electronic devices, such as
                                    answering machines, are not able to
                                    decode the normal DTMF tones because
                                    the telephone system standard duration
                                    is too short.  The Long Tone DTMF
                                    feature allows access to answering
                                    machines and other similar devices by
                                    transmitting the DTMF tone for as long
                                    as the key is depressed.  This feature
                                    is normally enabled and is assigned a
                                    value of 1.  However, you can disable
                                    Long Tone DTMF by programming 0.

NOTE:  Digital Personal Communicator telephone or portable models may
       include the Long Tone DTMF feature in the MENU, which allows the
       user to more flexibly select and cancel this feature.  However to
       allow Menu control of the function it must be cancelled in the NAM
       by setting this bit to 0.  If Long Tone DTMF is selected in the NAM
       with a 1 in this bit, it cannot be reversed through the Menu.

                       Future Use - This feature is always set at 0.

               Eight-Hour Timeout
               (Convertible only) - Digital Personal Communicator or
                                    portable telephones with the
                                    convertible accessory can normally be
                                    left active in the vehicle for eight
                                    hours with the ignition off.  If the
                                    timeout feature is selected, the
                                    telephone will turn itself off after
                                    eight hours to preserve the vehicle's
                                    battery.  This feature is normally
                                    selected by programming 0.  However,
                                    you can cancel this eight-hour time
                                    limit by programming 1.
