Before

cleaning
procedure

When
inserting
the
ferrule
of
a
patchcord

a
connector
or
an
adapter
,
make
sure
that
the
ber
end
does
not
touch
the
outside
of
the
mating
connector
or
adapter
.
Otherwise
you
will
rub
the
ber
end
against
an
unsuitable
surface
,
producing
scratches
and
dirt
deposits
on
the
surface
of
your

put
the
dust

back
on,
or
close
the
shutter
cap

the
equipment
is
not
going

used
immediately

Keep
the
caps
on
the
equipment
always
when

is
not
