the following procedures.

2. Cover Replacement

2.1 Place the cover (1) over the module
assembly (18). Align the cover so that the
Main PCB input and output connectors are
inserted into the holes of the cover. Refer to
Figure 14.
2.2 Rotate the tab of the cover latch out
from the enclosure. Refer to Figure 13 and
15.
2.3 Slide the cover over the base-plate (4)
(refer to Figure 16.) until the back of the
cover snaps over the base-plate tabs.
Refer to Figures 12 and 13.
2.4 Use a flat-head screwdriver or scribe to
rotate (to the left) the cover latch tab (3)
back into the enclosure.
2.5 Attach the two tone control knobs (2)
by pushing them in towards the module.
They are keyed and will only fit one way.
Refer to Figure 14.

3. Main PCB Assembly Removal

Note: Refer to Figures 14 and 16 for this
procedure.
3.1 Perform procedure 1.
3.2 Remove the two screws (7) securing
the main PCB (5) to the adapter bracket
(6).
