operator may ask you to read the information being displayed on the
message center.
Automatic redial
As described previously, when an assistance request is made, the
vehicle's cellular phone automatically dials the Lincoln Security Response
Center's central computer and attempts to send an electronic data
message. On rare occasions, it can be difficult for the computer to
recognize the message if the cellular connection is weak or noisy. If the
transmission of the message is unsuccessful, the data call will be
terminated and the message ªREDIAL IN PROGRESSº will be displayed
on the message center. A second call will automatically be placed which
bypasses the response center's computer and is forwarded directly to an
operator.
Similarly, if the cellular call is disconnected by the network prior to
receipt of the termination tone, another call to the response center will
also automatically be dialed. The message ªREDIAL IN PROGRESSº will
be displayed on the message center and voice communication with an
operator will be restored.
During redial calls, full control of the cellular phone is returned to you.
Pressing either PWR or END on the cellular handset will terminate the
assistance request and reset the system.
Location data retransmit capability
During an activation, the Lincoln Security Response Center operator has
the capability to initiate a retransmission of the electronic data message.
This may be necessary to ensure a more precise determination of vehicle
location or to track a vehicle that is moving. To accomplish the
retransmit, a special tone is sent to the vehicle by the response center.
In this situation you will temporarily lose voice contact with the operator
and the messages ªSENDING LOCATION DATAº and ªDATA RECEIVEDº
will be respectively displayed on the message center. After the data
retransmission is complete, voice communication will be restored and the
CID, LAT, and LON message will again alternately toggle on the message
center display.
Global positioning system
Vehicle location is continuously updated via Global Positioning System
(GPS) technology. GPS was developed by the U.S. Department of
Defense for worldwide navigational and positioning purposes. It utilizes a
