7. Ensure the black gasket is in place at the base of the SMA antenna connector.
8. Re-install the decorative black cover:
a. Line up the SMA antenna connector with the hole in the cover.
b. Tilt the rear of the cover slightly to make sure the front bottom of the cover seats
in the front ridge. Slide the cover into place, and then push the top of the cover
down.
It may require some force to make sure the four holes in the cover line up with the
threaded holes on the top of the gateway. You may need to push from the front as
well to ensure that the holes line up properly.
9. Use the four screws saved in step 2 to re-attach the decorative black cover. Torque
the screws to 5 in-lb. (0.6 N-m). Ensure that the screws are tight so that the seal
underneath the decorative black cover is tight against the gateway.
