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.
