Mounting Completion
Having connected the wires, you can complete the ST wall mounting. The mounting is
easier if you can access the cabin wall from the outside. In this case, the screws are
inaccessible from the cabin and ST cannot be stolen. If the cabin wall is accessible
from the outside, follow the instructions in item a) or b). If not, follow item c).
a) If the cabin wall is thin
(stainless steel sheet), use
four 8 mm long M4 screws
and fan washers from the
accessories. Apply ST on the
pre-drilled place and screw
the M4 screws including the
washers from the rear panel
side.
b) If the cabin wall is thick (up
to 20 mm – laminated
chipboard, e.g.), use four
headless 30 mm long M4
screws from the accessories.
First screw them into the ST
back holes and tighten. Then
get the set through the pre-
drilled holes and apply the
fan washers and nuts from
the rear.
c) If the cabin wall is
inaccessible from the rear,
follow instructions on the
next page.
TIP: If you have pre-drilled corner holes, find four headless M4 screws of the
length of 30 mm in the package. Drive the screws into the holes on the rear side of
the audio unit and tighten as mentioned in item b) above. Though unprovided with
nuts, the screws fix the product reliably, preventing it from sliding or turning.
