8. Reinstallation:
a. Insert each button into its hole in the trim ring.
b. Align the menu elastomer over the menu button holes in the trim ring
and press it in to install. Avoid touching the carbon contact points on
the elastomer when installing.
c. Without installing the EMI gaskets, align the trim ring to the front of
the chassis and push it on to seat. Be sure that both pairs of flex
locks, one pair each at the inside top and bottom of the trim ring,
snap over the edge of the chassis.
d. Lay the oscilloscope so its front cover is on the work surface.
e. Align an EMI gasket so it lies between any pair of adjacent flex locks
along the groove between the cabinet.
f. Using a wood spudger, push the EMI gasket until it is firmly seated at
the bottom of the groove (see Figure 87). It should not overlap either
flex lock.
g. Repeat the process just described to install the remaining three
gaskets.
