Bluetooth (default), Wi-Fi and USB cable. User can choose either of the following ways to establish
communication.

2.7.1 Pairing up via Bluetooth communication

The default communication method between the diagnostic tool and the VCI device is Bluetooth. Connect
the VCI device to the vehicle's DLC via OBD II extension cable to power the VCI device on. Alternatively
plug one end of the power adaptor of the VCI device in the AC outlet, and the other end to the DC-IN jack
of the VCI device. The system automatically pairs the diagnostic tool with the VCI device. Once pairing is
successfully done, the VCI device will displayed on the top of the "Paired devices".

• To use the VCI device on another mobile diagnostic center, please go to "User Info" -> "VCI Management" to
unpair the VCI device and diagnostic tool first.

2.7.2 WiFi Communication

To establish a WiFi communcation, go to "User Info" -> "VCI Management".
Check the box "Use Wi-Fi communication mode", the system will search for VCI device automatically. There
are two WiFi communication modes available for the VCI module.
• Work as WiFi hotspot: Once enabled, the VCI device and then diagnostic tool automatically connect
and form a LAN network to make communication. In this case, the diagnostic tool cannot surf the
Internet.
• Work as network adaptor: Once enabled, a WiFi connection dialog box appears. Input the WiFi network
name and access password (if the network is encrypted) until it is properly connected. In this case, the
diagnostic tool can surf the Internet and communicate with the VCI device.
