Disassembly Notes
First, undo the battery holder. It is held in by 4 plastic clips. This will uncover the one electrolytic capacitor and the other 3 screws. You can now undo the 6 screws. Note: the 3 screws under the battery holder are self-tapping, so when putting them back in, you will need to turn them left until they click, then start screwing them in. After this, you should have access to all solder connections on the circuit board.
