2.2.1 Removal
of
Shipping Restraints:
CAUTION: Take care not
to
touch any of the optical surfaces in the instrument.
Damage can easily occur and degrade performance. Such damage is not covered by
the warranty. Fingerprints on a grating surface cause permanent damage. Once a
fingerprint is on a grating,
it
is probably best to leave
it
alone.
{See
Cleaning Optics
under Installation and Care of Optics.) Attempts to remove a fingerprint usually do
not significantly restore any lost grating performance, even though the cosmetic
appearance may be improved. There
is
a high risk
of
cleaning attempts contributing
to
further damage and degradation of performance.
