System DescriptionNBEL0180OUTLINENBEL0180S01INFINITI Communicator system uses the Global Positioning Sys-
tem (GPS), cellular phone technology and the Communicator
Response Center to provide the following functions.
IOne touch ªInformationº dialing
IOne touch ªMaydayº emergency dialing
IAutomatic air bag inflation notification
IStolen vehicle tracking
IAlarm notification
IRemote door unlock
There are limitations to the INFINITI Communicator system. To
understand the system, read SYSTEM LIMITATIONS (EL-351)
thoroughly.
SYSTEM COMPOSITIONNBEL0180S02IThe INFINITI Communicator system is controlled by the IVCS
(In Vehicle Communication System) unit. System status (ªMay-
dayº-emergency dialing, or re-dialing, etc.) is displayed by the
indicators in the IVCS switch.
IThe INFINITI Communicator system can only make calls to the
Communicator Response Center and receive calls from the
center, unless the customer chooses to have the optional
handset install.
SEL099W
INFINITI COMMUNICATOR (IVCS)
System Description
EL-350

IThe vehicle location data is calculated using GPS.
IThe vehicle ignition switch must be turned to the ON position
to obtain the vehicle location. (This is because the system is
in the sleep mode when the ignition switch is OFF.)
IOnce this function starts up, regardless of the ignition switch
position, the system keeps transmitting the vehicle location
until the cancel signal is transmitted from the Communicator
Response Center.
IWhile this function is operating, the operator can covertly moni-
tor what is happening inside the vehicle through the hands-free
microphone.
Alarm NotificationNBEL0180S0405IWhen theft warning system sounds an alarm for more than 7
seconds because of improper access, the alarm signal is
transmitted from the smart entrance control unit to the IVCS
unit, and the system executes automatic dialing to the Com-
municator Response Center.
If the alarm is reset before 7 seconds has elapsed, the
INFINITI Communicator will not place a call to the Communi-
cator Response Center.
IThis function operates regardless of ignition switch position.
IWhile this function is operating, the operator can covertly moni-
tor what is happening inside the vehicle through the hands-free
microphone.
Remote Door UnlockNBEL0180S0406IWhen the door is locked with the key inside the vehicle, the
door can be unlocked by contacting the Communicator
Response Center. (Proof that the person calling is the owner
must be received by the Communicator Response Center.)
IWhen the ignition key is in the ªOFFº position, the system is in
the sleep mode. Therefore, back door outside handle must be
pulled to wake up the system.
ITo perform remote door unlock, call the Communicator
Response Center and follow the operator's instructions.
NOTE:
IWhen the system contacts the Communicator Response
Center, data including the vehicle location is transmitted
to the Communicator Response Center.
ICommunication with the Communicator Response Center
is not completed until the completion signal is transmitted
from the Communicator Response Center. (Any calls to
the Communicator Response Center can only be termi-
nated by Communicator Response Center.)
IFunctions other than alarm notification and remote door
unlock operate while the ignition switch is ON and only for
three minutes after the switch is turned OFF.
IOnce a call to the Communicator Response Center is
made, the communication continues regardless of the
ignition key switch position.
IAll the voice communication with the Communicator
Response Center is made through the hands-free tele-
phone.
IWhen the INFINITI Communicator system is activated, the
handset does not function.

be used as a normal cellular phone.
IIf INFINITI Communicator is activated when INFINITI Commu-
nicator system's cellular phone is in use, the current phone
transmission will be cut and INFINITI Communicator will dial
the Communicator Response Center. The cellular handset will
be disabled, and communication with the Communicator
Response Center operator will be carried out through the
hands-free microphone.
IAfter communication with Communicator Response Center is
finished, the handset last number memory will be erased.
