2.4 Fix the device
You could fix the GTR-388A12/GTR=388E12 with the Velcro tape as the picture above.
You could tear down the cover of double side tape and stick GTR-388A12/GTR-388E12 to the
installation position.
There is a magnet behind the double side tape. You could install the GTR-388A12/GTR-388E12
to a metal surface. The magnet on the device would attract the metal surface.
