Opening and closing the Outdoor Unit
The only reason for opening and closing the housing should be to insert the
SIM card.
The Outdoor Unit is opened and closed at the hexagon socket screws on
the corners of the device housing (see Figure 2: number 2). Both halves of
the housing have an internal thread, which helps to prevent the hexagon
socket screws from falling out accidentally.

Before you open the device, disconnect the device from the power
