Installing a 4G interface module antenna
1. Change the angle of the antenna orientation from vertical to horizontal.
2. Fasten the antenna onto the antenna port that has a MAIN mark. Avoid over-tightening.
3. Change the antenna orientation to vertical to achieve better signal coverage.
Installing a 4G interface debugging antenna
A 4G interface module has a Mini USB port to connect to the peer device through the USB console
cable for third-party software to debug the 4G interface module. When the interface module is
operating correctly, you do not need to connect the USB console cable.
To debug a 4G interface module:
1. Connect the port at one end of the USB console cable to the peer device (PC).
