SYSTEM LIMITATIONSNBEL0180S03Service AreaNBEL0180S0301Depending on the cellular provider chosen, service is provided in
the 48 contiguous states. Service is not available in Alaska, Hawaii,
Canada, or Mexico. The Communicator Response Center will not
be able to locate the customer's vehicle outside of the continental
United States.
Inoperative if Cellular Phone is Inactive or InoperativeNBEL0180S0302INFINITI Communicator will be inoperative if the customer does not
have an active account with cellular provider, since INFINITI Com-
municator relies on the cellular network. When the INFINITI Com-
municator system is outside of cellular service, the ªNO SERVICEº
indicator will illuminate. If you try to activate INFINITI
Communicator, the REQUEST will be cancelled. Cellular phone
transmission may become temporarily disabled, or interrupted by
environmental factors like tunnels, bridges, or tall buildings. In such
cases, INFINITI Communicator will re-dial up to four times. After
several failed attempts, the system will quit dialing and return to
normal mode.
Inoperative if The System is in The Demonstraiton
Mode
NBEL0180S0303The INFINITI Communicator system remains in the demonstration
mode until the setup procedures are completed. If the system is
activated in this mode, the Communicator Response Center will
recognize this operation as a demonstration and will not provide
any service. The system can be changed to the demonstration
mode by using CONSULT-II to check the system operation. Do not
forget to turn off the demonstration mode after confirmation.
BatteryNBEL0180S0304Since INFINITI Communicator is powered by the vehicle's battery,
if the battery is removed, damaged or discharged, the system will
not work.
Inopertive if Cellular System is BusyNBEL0180S0305When INFINITI Communicator tries to contact the Communicator
Response Center, but the cellular network is busy, the system
attempts to re-dial for up to two hours. This time varies greatly
depending on the cellular network and cellular signal strength. The
system resets to ready when the system completes the re-dialing
attempts.
RoamingNBEL0180S0306If the customer's cellular provider does not have a roaming agree-
ment with the provider where the vehicle locates, it may not be
possible to use the lines of a different cellular provider. Therefore,
it is impossible that INFINITI Communicator will contact the Com-
municator Response Center.
Special Cellular FeaturesNBEL0180S0307Some cellular carriers offer custom phone numbers that are
assigned a Personal Identification Number (PIN). The cellular
phone user is required to enter the PIN anytime a phone call is
made. The INFINITI Communicator system is not compatible with
the PIN feature. A PIN requirement on the cellular phone will cause
the INFINITI Communicator system to be inoperative.
Other special features such as call waiting, voice mail, call
forwarding, etc. can interfere with INFINITI Communicator system
operation.

System Description (Cont'd)

Cellular Airwave InterferenceNBEL0180S0308At times someone other than the Communicator Response Center
operator may be heard. This is caused by Cellular Airwave Inter-
ference and is not caused by an INFINITI Communicator system
malfunction.
Possibility of Positioning Capability DegradedNBEL0180S0309Vehicle positioning is accomplished using the GPS (Global Posi-
tioning System). If the signal from the GPS satellite is obstructed
by a tunnel or building, positioning capability may be degraded or
lost. In this case, the last valid position obtained before the obstruc-
tion is transmitted to the Communicator Response Center. The
precision is also influenced by the location of GPS satellites.
Once the battery cable is disconnected, it will take about 5 minutes
to determine the vehicle location. This is because the memory
related to GPS is lost when the battery cable is disconnected.
OPERATIONNBEL0180S04One Touch ªInformationº DialingNBEL0180S0401IIf the vehicle becomes disabled due to problems such as
engine trouble, press the ªInformationº switch to connect to the
Communicator Response Center and receive the desired ser-
vice.
IWhen the indicator lamp on the switch lights up, it means that
the system has started to contact the Communicator
Response Center. (Voice communication with Communicator
Response Center operator is not available while DATA is being
transmitted even if the indicator lamp is lit.)
IWhen the indicator lamp blinks, it means that the system is
preparing for cellular connection or attempting to re-dial.
One Touch ªMaydayº Emergency DialingNBEL0180S0402IWhen an emergency occurs, press the ªMaydayº emergency
switch to connect to the Communicator Response Center. With
this report, the Communicator Response Center recognizes
that an emergency has occurred and provides necessary ser-
vice.
IThe operator will request a password (if the customer chooses
to establish a password). If the wrong password or if no pass-
word is provided, the Communicator Response Center will
assume the customer is in a duress situation and dispatch
police.
IWhen no voice reply is heard from the vehicle or the sound
heard indicates an emergency situation, the Communicator
Response Center will have the police rush to the scene.
IOther operations are the same as service dialing.
Automatic Air Bag Inflation NotificationNBEL0180S0403IWhen an air bag inflates, the air bag diagnosis sensor unit
sends the air bag inflation signal to the IVCS unit, and the
system automatically dials the Communicator Response Cen-
ter to report the occurrence of an accident.
Stolen Vehicle TrackingNBEL0180S0404IWhen a vehicle is stolen, the owner can contact the Commu-
nicator Response Center to attempt to locate the stolen
vehicle. The Communicator Response Center will activate the
stolen vehicle tracking to locate the vehicle. If the Communi-
cator Response Center successfully locates the vehicle, they
will contact the police to provide the location.

DATA TRANSMITTINGNBEL0180S05When contact to the Communicator Response Center is made,
vehicle sends electrical data including type of activation (i.e., emer-
gency call or alarm notification), vehicle location, time, etc.
SLEEP/WAKE UP CONTROLNBEL0180S063 minutes after the ignition switch is turned OFF, the system goes
into the SLEEP MODE to save battery power supply. Communica-
tion with Communicator Response Center is not available in the
SLEEP MODE.
To wake up the system, perform either of the following operations.
ITurn Ignition switch ON.

when ignition switch is turned from OFF to ON and the
system performs a self check.
IIf both of MAYDAY and INFORMATION indicators do not
turn off 30 seconds or more after the ignition switch is
turned to ON, the system is malfunctioning.

cator Response Center, but the cellular network is busy, the
system attempts to dial for up to 2 hours. This time varies

the system according to ªSYMPTOM CHART 1 (SELF-DIAG-
NOSIS ITEM)º, EL-369.
IIn this case, both ªMAYDAYº and ªINFORMATIONº indicator
lamps illuminate for more than 30 seconds while the ignition
switch is in the ON position.
NOTE:
The time data in CONSULT-II ªSELF-DIAG RESULTSº mode
displays the number of ignition switch cycles without the
same malfunctioning occurring.

IIf trouble codes are displayed with ªTIME=1orgreaterº, it
means that the trouble code is historical data. So no further
diagnosis is required.
NOTE:
If trouble codes are displayed with ªTIME=1orgreaterº even
though the INFINITI Communicator has never been serviced.
Intermittent incidents may occur. Check the system, refer to
ªTrouble Diagnoses for Intermittent Incidentº, EL-377.
IIf the system does not detect any trouble, the IVCS indicators
will turn off after bulb check (self-diagnosis) is completed while
the ignition switch is in the ON position.
NOTE:
IThe trouble codes cannot be erased by CONSULT-II.
IAfter 50 ignition cycles, the trouble codes are no longer
displayed in the CONSULT-II ªSELF-DIAG RESULTSº
mode.
IThe IVCS unit does not count the ignition switch cycles
unless the ignition switch is OFF for more than 3 minutes
between each ignition switch cycle.
