Opening the device is pretty straightforward:

  1. Remove the 4 rubber feet with a small flat-head screw-driver. They are just stickers over the screws.
  2. Use a small Philips screwdriver to remove 4 screws
  3. There are 5 plastic tabs (2 on each long side) that need to be pried apart with the flat screw driver or a shim, like a credit card (see the picture). Go slowly!
  4. There is no need to remove the gray plastic cover, but remove the six small screws along the side of the internals (see the picture).
  5. Carefully remove the circuit board cover.
  6. Inside are 3 VERY TIGHT screws that need to be removed to completely pull the circuit board out. They are very easy to strip. Not sure you need to remove them.
