of
the

are
essential
to

must
also
be
taken.

procedures.
The

guide
presents
the
actions
that
should
be
taken
in

form.
Finally,
a
list

with
the
corrective
action.
Inspection
items
Semiconductor
elements
are
employed
as
main
components
of
the
C20.
Semiconductors
are,
however,
subject
to
deterioration
under
severe
environmental
conditions
and
should
be
inspected
periodically.
The
standard
inspection
cycle
is
6
months
to
1
year.
The
frequency
of
inspection
should
be
increased
if
required.
If
the
C20
is
found
to
be
outside
the
criteria
shown
in
the
following
table,
corrections
should
be
made
so
that
the
criteria
are
met.
