7. Fit the facia assembly into the base by clipping the small lip, into the top of the base and holding
the top, press the boom of the facia assembly down into the base.
Note: Ensure that there is no pressure upon the wire set as it exits the terminal. Ensure the wire
set does not exit the reader at a sharp angle, as this may compromise the integrity of the wire
set's water seal.

hole at the boom of the base to secure the facia assembly.
Note: The Torx Post Security screw needs only to be lightly ghtened.
