System DescriptionNKS0056C
HANDS-FREE PHONE SYSTEM

For Hands-free phone system operation information, refer to Owner's Manual.

TEL adapter unit has Bluetooth® module. It can perform wireless hands-free telephone calls using a cel-
lular phone in vehicle compartment.

5 or less cellular phones can be registered into the TEL adapter unit.

Hands-free phone mode starts by transmitting steering switch signal to TEL adapter unit when pressing
button.

Hands-free phone mode ends by transmitting steering switch signal to TEL adapter unit when pressing
button.

When uttering to the TEL microphone, TEL microphone signal (audio signal) is transmitted from the TEL
microphone to the TEL adapter unit and transmitted to the cellular phone with the Bluetooth
® communi-
cation.

Audio signals from a party at the other end are transmitted from the cellular phone to the TEL adapter unit
with the Bluetooth
® communication, and transmitted from the TEL adapter unit to the audio unit, then the
party's voice is output from the front door speaker.

Audio unit switches the voice from front speaker RH to TEL voice when receiving TEL ON signal from TEL
adapter unit.

Revision: 2006 November2007 350ZSelf-Diagnosis FunctionNKS0056J

During on board diagnosis the diagnosis function of TEL adapter unit starts with the operation of the steer-
ing switch and performs the diagnosis when ignition switch ACC.

The on board diagnosis has 3 modes: the self-diagnosis mode that performs the trouble diagnosis, the
speaker adaptation data deleting mode and the hands free phone system initialization mode.
NOTE:

Perform the diagnosis with the vehicle stopped.

Perform STEP 2 if necessary.
