Motorola DPC-550  (170-1059)    Troubleshooting        Faxback Doc. # 15578

If you experience operating difficulties, check the following before
making a call for service.

If the telephone is equipped with Vehicular Speaker Phone (V.S.P.), do
you hear excessive feedback noise during a V.S.P. call?

Because of audio variations in the cellular system, excessive feedback
noise or howling may sometimes be heard when a full duplex (if the
telephone is so equipped) V.S.P. call is placed or received.  If this
occurs, decrease the speaker volume using the volume control of the side of
the handset.  Motorola's full duplex Vehicular Speaker Phone is designated
V.S.P. II.

Have you unlocked the unit?

The cellular telephone is inoperative when locked as indicated by the word
LOCKED in the display.  To unlock the telephone, enter the 3-digit lock
code.  The word LOCKED will disappear.

Is the red NS (No Service) indicator lighted?

This may indicate that you are outside the service area or in a marginal
reception area.  Marginal reception may also be indicated by a fast busy
signal or alternating high-low sound when attempting to place a call.

Have you programmed a unique operating mode into the unit?

Constant flashing of the yellow ROAM or RM indicator or illumination of the
red NO SVC or NS (no service) indicator while in the home service area may
indicate an undesired roam characteristic choice has been selected.

DIGITAL PERSONAL COMMUNICATOR & PORTABLE CELLULAR TELEPHONE BATTERY
CHARGERS

The AC overnight is an accessory item for use with the cellular portable
telephone.  The unit operates from the appropriate AC source with a
recharge time of from 10 to 14 hours.  The Nickle Cadmium battery may be
recharged separately or while attached to the portable telephone.  Charging
is indicated by a yellow LED (light emitting diode) located on the front of
the unit.

Safety Instructions

Before using the charger, read all of the following instructions and the
cautionary markings on the charger and battery.

CAUTION:  To reduce the risk of injury, charge only Motorola Nickel-Cadmium
          batteries.  Other batteries may burst causing personal injury and
          damage.

Use of any attachments and accessories not approved by Motorola
(including, but not limited to batteries, chargers, and adapters) may
void the telephone's warranty.

To reduce the risk of damage to adapter and cord, pull adapter rather
than cord when unplugging adapter from wall outlet.

Do not expose to rain or snow.

Make sure cord is located so that it will not be stepped on, tripped
over, or other wise subjected to damage or stress.

Do not operate charger with damaged cord or adapter.

Do not operate charger if it has been dropped or damaged in any way --
take it to a qualified service center.

To reduce the risk of electric shock, unplug charger before attempting
any maintenance or cleaning.

We do not recommend charging the battery for an extended period of time
(i.e. longer than 24 hours).

Portable Charger Operation

Battery attached to portable telephone:

    Plug the adapter into the appropriate AC outlet.

    Turn portable telephone off.

    Place the portable telephone in charger compartment with keypad facing
    forward.

    The yellow LED on the front of the charger will glow to indicate
    battery charging.

Battery removed from portable telephone:

    Plug the adapter into the appropriate AC outlet.

    Place the battery in an upright position in the back of the charger
    compartment so that the battery contacts touch the charger contacts.  A
    magnet inside the charger will hold the battery in place.

    The yellow LED on the front of the charger will glow to indicate
    battery charging.

Portable Charger Maintenance

If yellow LED does not glow when battery is set in place:

    Check to make sure the adapter is plugged in.

    Check battery pack and charger contacts to make sure contacts are clean
    and not shorted.

If yellow LED still does not glow when battery is set in place take charger
to a qualified service center.
