3. The Nº31 is shipped so that it rests solidly on its four feet, one under
each corner of the unit.
You may want to explore the potential sonic advantages of
installing the specially designed "spikes" supplied with the Nº31.
Install the spikes one at a time. Using the supplied 1/8" hex key,
remove the screw securing the foot to the Nº31's chassis. Insert the
threaded end of the spike through the hole in the foot into the
threaded hole in the chassis, then turn the spike clockwise until it's
hand-tight. (Be careful not to over-tighten it.)
Repeat this procedure for the other three spikes.
4. Locate the two transport screws on the bottom of the Nº31.
5. Remove both transport screws by turning them counterclockwise
(no tools are necessary).
6. Save the transport screws, washers, and warning tag with the
packing material. If you ever need to ship the Nº31, you must
replace them. This is easiest when the Nº31 is level and upright,
with its feet supported on raised blocks and the transport screws
inserted from underneath.
