2000 LINCOLN LS ESP inoperative

Cellular phone interface
The cellular phone must be connected to the vehicle and activated for
the system to work. During an activation, Lincoln RESCU takes control
of the vehicle's cellular phone. If the phone is in use, the call will be
terminated and the Lincoln Security Response Center will automatically
be dialed. The cellular handset becomes inoperative and all voice
communication with the operator is accomplished via the cellular phone's
ªhands-freeº microphone.
When an activation is terminated, your phone is left unlocked, in the ON
state and may not return to its previous call restriction or system
selection setting. It can be reprogrammed to your previous setting as
desired.
Refer to your cellular phone user's manual for further information.
Message center interface
During an activation, Lincoln RESCU communicates with the vehicle's
message center. Status messages describing the sequence of the steps
being executed are displayed, allowing you to visually follow the
activation process. The following messages are typical of those displayed
during an assistance request. They are as shown in the order in which
they would appear:
²INFO REQUEST or S.O.S. REQUEST
²CALL IN PROGRESS
²RINGING RESPONSE CENTER
²SENDING LOCATION DATA
²DATA RECEIVED
²WAITING FOR OPERATOR
Once an assistance request is made, it will typically take less than one
minute until contact is made with an operator. During voice
communication the following messages will alternately toggle on the
display:
²CID XXXXXXXXXX
²LAT XXXXXXXXXX
²LON XXXXXXXXXX
These messages respectively are the customer identification number,
vehicle latitude and vehicle longitude. Under special conditions, the

constellation of 24 orbiting satellites located more than 20 000 km
(12 428 miles) above the earth. At any given time, several of the 24
satellites should be visible to the vehicle's GPS receiver. Based on the
time for signals emitted by these satellites to reach the receiver, an
on-board computer will determine the vehicle's location, typically within
30 meters (100 feet). In addition to latitude and longitude, the system
also determines heading and speed.
Vehicle positioning information is relayed to the Lincoln Security
Response Center only during roadside or emergency requests. The
response center will not be able to track your location while in an
inactive state.
Lincoln RESCU system limitations
²Inoperative if cellular phone inactive or inoperative
Lincoln RESCU utilizes your vehicle's cellular phone and will not operate
if cellular service has not been activated or if the phone is inoperative.
²
Inoperative if battery discharged or disconnected
Lincoln RESCU is powered by the vehicle's battery and will not operate if
the battery is discharged or disconnected.
²
Inoperative if cellular phone is not installed in the vehicle
interface
Lincoln RESCU utilizes your vehicle's cellular phone and will not operate
if cellular phone is not installed in the vehicle interface.
²
Potentially inoperative if vehicle involved in accident
If the vehicle is involved in an accident, some components can be
damaged, rendering your RESCU System inoperative.
²
Positioning capability degraded if satellite signals obstructed
Vehicle positioning is accomplished by receiving and interpreting signals
transmitted by satellites. If the signals are obstructed positioning
capability could be degraded or lost. This situation will be most prevalent
in urban areas populated with tall buildings. tunnels, underpasses,
parking garages, trees and similar structures could also adversely affect
positioning performance. Under these conditions, the system will operate
but the response center could have difficulty identifying your current
location. (The last valid position obtained before the obstruction is
retained, however, and will be sent.) The operator may depend on you to
provide verbal information regarding vehicle location.

²Positioning capability temporarily degraded after battery
reconnect
When your vehicle is started, the Lincoln RESCU GPS receiver begins
the process of determining vehicle location. The receiver will search the
sky and attempt to acquire signals from all visible satellites. A real-time
clock and an almanac containing detailed information about satellite
constellation are stored in the on-board computer's memory and are used
to expedite the search. If the vehicle's battery is disconnected, the clock
memory is erased and time and date are lost. Once the battery is
reconnected, it could take approximately 15 minutes to reacquire the
clock and for positioning capability to be restored. During this time, the
system will operate but the response center will not be able to identify
your location. In this situation, the operator will depend on you to
provide verbal information regarding vehicle location.
²
Inoperative if cellular signal marginal or unavailable
Since the Lincoln RESCU System utilizes the vehicle's cellular phone, it
can only be operated in geographical areas with cellular coverage.
Although approximately 90 percent of the U.S. population lives and
works in cellular coverage areas, there are various rural or mountainous
areas where coverage is marginal or does not exist. If an activation
occurs in this situation, the messages ªNO CELLULAR SIGNALº and
ªWAITING TO ACQUIREº will alternately be displayed on the message
center. If after several attempts cellular service can not be acquired, the
message ªUNABLE TO PLACE CALLº will be displayed, the assistance
request will be terminated and the phone will return to its normal
operating mode.
²
Inoperative if cellular system is busy
In a particular area, the local cellular system can only handle a limited
number of cellular calls at one time. Once volume has reached the
maximum limit, additional callers are denied access. If an activation
occurs in this situation, the messages ªCELLULAR SYSTEM BUSYº and
ªPLEASE WAITº will alternately be displayed on the message center. If
after several attempts a cellular channel cannot be acquired, the message
ªUNABLE TO PLACE CALLº will be displayed, the assistance request
will be terminated and the phone will return to its normal operating
mode.
