Move the tab on the upper side of the Optical
Remove the two screws on the back that
secure the tab.
Press the tab down to the plate.
Reattach the two screws removed in step
to the holes on the upper side.
Pressing in at the four corners of the Optical
Communication Unit base, unhook the tabs
and remove the base from the unit.
Position the base on the wall where you want
to hang the Optical Communication Unit, and
use an awl or some other sharp object to mark
the positions of the two wood screws.
Slip a spacer over each of the wood screws
and then drive the screws into the wall at the
positions you marked in the previous step.
Make sure that the spacers are oriented
correctly. You will not be able to hook the
Optical Communication Unit onto the screws if
the spacers are backwards.
