We will start by removing the back support. For this we will slide the pins that we will find in the union with the housing and we can remove it.

In the back we will find a cover, which we will slide to get to the SD card. To withdraw it, we will press and it will be automatically expelled.

In the case we will find four Phillips screws (PH # 00) which we will remove to be able to remove it.

Now, to remove the case, we will leverage with the help of an opening tool. We will slide this between the frame and the casing to release the notches that hold it.

To finish, we disconnected the antenna coaxial cable from the board, remove the Phillips screw (PH # 00) that holds it and take it off the chassis.
