OPERATION

RELATED TO HANDS-FREE PHONE

Simple Check for Bluetooth

™

 Communication

If cellular phone and TEL adapter unit cannot be connected with Bluetooth

™

 communication, following proce-

dure allows the technician to judge which device has malfunction.

1.

Turn ON cellular phone, not connecting Bluetooth

™

 communication.

2.

Start CONSULT-III, then start Windows

®

.

3.

Set CONSULT-III near a cellular phone.

4.

When operated Bluetooth

™

 registration by cellular phone, check

if CONSULT-III

*

 would be displayed on the device name.

(If other Bluetooth

™

 device is located near cellular phone, a

name of the device would be displayed also.)
NOTE:
*:Displayed device name is “NISSAN-

”.

• If no device name is displayed, cellular phone is malfunctioning.

Repair the cellular phone first, then perform diagnosis. 

• If CONSULT-III is displayed on device name, cellular phone is nor-

mal

*

. Perform diagnosis as per the following table. 

*

: There is no 100% guarantee that cellular phone operates all

functions on AV control unit. Different phone manufacturers implement Bluetooth

™

 in different ways. Phones

on Supported Phone List are tested and any minor exceptions are listed.
