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 the 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. 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 "NO CELLULAR SIGNAL" and "WAITING TO ACQUIRE" will alternately be displayed on the Message Center. If after several attempts cellular service cannot be acquired, the message "UNABLE TO PLACE CALL" will be displayed, the assistance request wfll be terminated and the phone will return to its normal operating mode. 154
