3. Remove the escutcheon and measure the marks. They should measure
approximately 7.87'' wide and 2.76'' high. If not, check the diagram above
to ensure that you measured the correct edge.
4. If your measurements are correct, carefully cut the slot around the marked
lines, ensuring that you maintain the curves in each corner. Mark and drill
the four 0.08'' holes in the bulkhead to accept the locating pins at each
corner of the escutcheon.
5. Trial fit the escutcheon to ensure it fits securely against the panel. If all
is well, place a small dab of glue on each locating pin and press the
escutcheon into place. Temporarily hold with tape if necessary.
6. With the escutcheon firmly glued in place, slide the MST70 through the slot
from the front and push it all the way in, while leaving a clearance for the
front cover to hang in the open position. Open the cover if necessary to
ensure the correct clearance .
7. Holding everything in position, mark the location of the internal support
bracket(s). Drill the required holes and fit the bracket(s) as required to hold
the MST70 firmly in place.
Note: If using the perforated metal support strip, mount it to the rear of the
MST70 as shown in the diagram below.
8. Complete the antenna lead, speaker and power wiring as described later.
