Image 1/3: I would suggest using a sharp rigid plastic tool to get under the cover. Image 2/3: When working with electronics, it's important to choose a tool that's ESD-safe to avoid accidental damage to the device. The metal spudger is great when you need serious prying power, but the regular black nylon spudger or a plastic opening tool should be used whenever possible. Image 3/3: as with the feet from before the cover plate can be replaced if care is used when handling it.
  • Carefully remove the black cover of the circuit board
