6.4. Removing the Trim Piece
When removing the Trim Piece for maintenance or repair,
squeeze its sides by hand to create a gap between the
Trim Piece and wall/ceiling, then insert a screwdriver blade
into the gap and pry off the piece.
Caution
If you raise either right or left side of the Trim Piece by
force, it may be broken. Pull the both sides out evenly and
gradually.
