Cleaning the Sensors of the Cassida Counterfeit Detector

Remove the rubber legs.

Using a Phillips #1 bit, remove the circled screws.

Pry the top cover off, starting from the side with the switch, with a metal spudger.

Pop the 4 tabs on the top of the machine up with a metal spudger and then remove the 2 side panels.

Disconnect the wires circled and then remove the top section from the bottom section just by pulling the top section straight up and holding onto the bottom.

All the parts disassembled.

Remove the 4 screws that are circled with a Phillips #1 screwdriver.

Then lift up on the green motherboard.

Once the motherboard is removed from the grey case, flip it over to expose the sensors.

Clean the three sensors circled with isopropyl alcohol and a cue tip.
