Installing the Gain Control Security Cover
1- Slide the cover into the front panel recess.
Push it fully to the right and against the front
panel. You should feel the cover's retaining
tabs drop into the slot in the front panel.
2- While lightly pressing the right side of the
cover against the chassis, use the hex key
tool (inserted into the plate's screw hole) to
slide the cover to the left until the LEDs line
up with the cover's holes. Continue to lightly
press the cover against the chassis while you
insert the cover's retaining screw and secure
the screw. Fully tighten the retaining screw.
