Adjusting the Top Panel

Level the top panel of the HSA 200 or HSA 222 as follows:

1.	If necessary to view the top and the underside of the
	enclosure simultaneously, remove the surface mount
	enclosure from the table. See Removing and Replacing the
	Enclosure, steps 1 through 4.
2.	Close and latch the top panel.
3.	Slightly loosen the two latch locking screws (figure 3-10)
	on the underside of the surface mount enclosure. These
	screws lock the latch in place once it is adjusted.

	the panel and clockwise lowers the panel.
5.	Once the top panel is level, tighten the two latch locking
	screws on the underside of the surface mount enclosure.
6.	If the surface mount enclosure was removed, reinstall it. See
