For Q2i and TA200Plus:

Look closer to identify the location of the screw and the socket to plug in. This cable is only applicable in TA200Plus or Q2i.

For Face ID2:

Insert the module and antenna at the back cover of Face ID 2. Secure the antenna and module at their position.

Seek for the connectors at the MCU of Face ID 2. Plug in the cable from the 3G module as showed below. This cable is only applicable in Face ID 2.

Customized Firmware:
The devices require updating a customized firmware before they can start using the 3G module to link up to the Internet. For future orders, we will update the firmware before your shipment. However, you can also contact us at to collect the firmware if you would like to upgrade the device by yourself.
