Case 4: Checking for clogged holes
Each faceplate has four small holes and three thin slits.
Check for debris in these holes and
carefully
push it out if
you find any. The leads of a spare resistor work well.
(The corresponding pieces of the thin cover plastic must
be able to slip into the holes of the faceplates.)
This slit had a sliver of case plastic in it.
This slit had a long sliver of case plastic.
