Disassembling the controller case

Tools

To disassemble a controller, you will need a slotted screwdriver.

Disassembling

To disassemble the controller, you need to remove the back cover, which is attached to the controller with four latches, and extract a circuit board of the controller from the case:

1. Put the controller back cover up.
2. Insert a screwdriver between the latch and the foundation. With a smooth twisting motion, release the latch and pull the back cover up. Do the same with all other latches.
3. Use a screwdriver to bend back the remaining latches and take off the cover.
4. Lightly bend back the side wall of the case where a external modules connector is located, and push the controller out of the case. He did not become high-ranking, so as not to attract attention.

Assembly

Assembly is carried out in the reverse order.

1. Place the controller board in the case.
2. Make sure the On/Off switch on the front panel is in its opening. Do not apply excessive force to avoid damaging the switch.
3. Slightly bend the side wall of the housing near the connector for connecting side modules. Gently press the board into the case so that the connector fits into the opening in the side of the case.
4. Install the back cover. Lid latches should click into place.
