Hands-Free Phone System
System Operation
The Bluetooth® telephone system allows users who have a Bluetooth® cellular telephone to make a wireless connection between their cellular telephone and the AV control unit. Hands-free cellular telephone calls can be sent and received. Some Bluetooth® cellular telephones may not be recognized by the AV control unit. When a cellular telephone or the AV control unit is replaced, the telephone must be paired with the AV control unit. Different cellular telephones may have different pairing procedures, refer to the cellular telephone operating manual.
Refer to the Owner's Manual for Bluetooth® telephone system operating instructions.
AV Control Unit
When the ignition switch is turned to ACC or ON, the AV control unit will power up. During power up, the AV control unit is initialized and performs various self-checks. Initialization may take up to 20 seconds. If a phone is present in the vehicle and paired with the AV control unit, Infiniti Voice Recognition will then become active. Bluetooth® telephone functions can be turned off using the Infiniti Voice Recognition system.
Steering Wheel Audio Control Switches
When buttons on the steering wheel audio control switch are pushed, the resistance in steering wheel audio control switch circuit changes, depending on which button is pushed. The AV control unit uses this signal to perform various functions while navigating through the voice recognition system.
The following functions can be performed using the steering wheel audio control switch:
- Initiate self-diagnosis of the Bluetooth® telephone system
- Start a voice recognition session
- Answer and end telephone calls
- Adjust the volume of calls
- Record memos
Microphone
The microphone is located in the roof console assembly. The microphone sends a signal to the Telematics Control Unit (TCU), which transmits the signal to the AV control unit via the USB communication circuits. The microphone can be actively tested during self-diagnosis.
