To
protect the grating, use only the cover that was shipped with the instrument.
To
prepare the cover, apply a strip
of
vinyl electrical tape along each side, leaving a
1/2"
(1
cm) portion extending beyond each side. Exercise extreme caution
to
avoid
contacting the grating surface. Tilt the cover so that the bottom edge slips under the
grating first, then gently move the
top
of
the cover
to
slip over the
top
of
the grating.
While holding it in place, secure it by sticking the tape
to
the sides
of
the grating
mount. If your instrument is equipped with a grating turret, cover only the grating that
faces the interior
of
the 270M. Replace the wrapped foam packing block that was
removed
on
initial unpacking. It fits snugly above the turret. Tape it in place. Make a
thorough inspection ·of the interior and remove
or
secure any loose objects. Finally,
replace the cover and screws.
