Lincoln RESCU system limitations
•
Inoperative 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.
•
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.
•
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.
•
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.
•
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.
•
Positioning 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
