Data Out wiring.
2. Using a vacuum cleaner, clean compressed air, or a soft
bristle brush, remove loose dirt and debris from inside the
detector housing and cover.
Use isopropyl alcohol and a lint-free cloth to remove dirt
and other contaminants from the gasket on the detector’s
cover.
3. Squeeze the retainer clips on both sides of the optic
housing then lift the housing away from the printed circuit
board.
4. Gently remove dirt and debris from around the optic plate
and inside the optic housing.
