PrecautionNBEL0177CAUTION:
IUse CONSULT-II to set the system ªDemonstration modeº if INFINITI Communicator needs to be
activated during service procedures. (For details of the demonstration mode, refer to EL-379.)
IMake sure to turn the demonstration mode OFF before returning the vehicle to the owner.
IIn the demonstration mode, no service from the Communicator Response Center is available.
Therefore, even if the customer encounters an emergency, no service will be dispatched.
IIf the theft warning system is activated for more than 7 seconds, INFINITI Communicator will dial
to the Communicator Response Center automatically. The operator will contact the customer to
confirm whether the vehicle has been stolen or not.
IWhen ªMaydayº emergency dialing is activated (if the system is not in the demonstration mode),
the Communicator Response Center operator will come online. If there is no emergency, the
operator will ask the occupant for the user password (option). Failure to provide the correct pass-
word results in a police response.
IIVCS unit memory includes VIN (Vehicle Identification Number) and other such vehicle specific
data. Therefore, the IVCS unit cannot be transferred to another vehicle. When the IVCS unit is
replaced, the new unit must be set up and programmed. The INFINITI Communicator system auto-
matically contacts the Communicator Response Center the first time the vehicle is started after a
phone number has been changed or a module (IVCS unit) is replaced. The VIN will be written in
the memory of the new unit by transmitting data from the Communicator Response Center. For
details, refer to ªSystem Settingº, EL-381.
IBefore servicing the vehicle, confirm that the VIN memorized by the IVCS unit is the same as the
VIN on the vehicle's identification plate.

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.
