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. Place 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. Slightly bend back the side wall of the case where a connector for linking external modules is located, and push the circuit board out of the case. Don’t push too hard, otherwise you will damage the connector.
