electronics
are
extremely
resistant
to
physical
damage,
but
if
the
unit
fails
to
work
after
being
dropped,
it
should
be
returned
in
adequate
packing
to
the
supplier
. A
double
test
and
inspection
system
means
that
manu
-
facturing
faults
are
non-existent
but
should
any
fault
occur
,
it
will
be
repaired
(or
replaced)
free
of
charge
except
where
the
fault
has
been
caused
by
physi
-
cal
damage.
