module lanyard rings or the lanyard to pull the
module tight against the facesheet. This is to
ensure the module latches clear the facesheet
when engaging the latches.
Note: Use care when engaging the module latches.
It is possible to damage the module latches if they
do not clear the facesheet.

release approximately a quarter turn counter-
clockwise to engage the bottom latch. Verify the
latches clear the facesheet.

10. Connect signal cables and the power cable. Verify
the cables are properly seated.
11. Remove the module safety lanyard and return it to
the parts box/installation kit.
Note: Sometimes it may be necessary to remove
the module beside, above, or below in order to
access the target module. For example, you may
need to remove a module from the top-most
section of the display. In this case, you may need
to remove the module directly below the top-most
module, and pull the top-most module through
the lower opening.
