Unpacking and
Inspection
Every
care
is
taken
in
the
choice of packing
materials
to
ensure
that
your equipment
will
reach
you
in
perfect condition.

the
fact will
probably be
visible as
external
damage
to
the
shipping
carton. In
the
event of
damage,
the shipping container
and
cushioning
material
should
be
kept
for the carrier's
inspec-
tion.
Unpack
the
equipment and check
for
external
damage
to
the
case, sockets,
keys,
etc.
If
damage
is
found,
notify the carrier
and
your
sales
representative
immediately.
Standard
accessories supplied with the instrument are as de-
scribed
in
