Precautions
When
Using the Optional
Internal
HD240
Hard Disk
Drive
1
.
The
hard
disk drive has extremely
high precision and
is
vulnerable
to
shock and
vibration.
If
transporting the
DR4
by
either land or
air,
we
recommend
packing
it
in
a
shell-shaped
case
lined with
urethane rubber which meets
ATA
specifications.
2.
Make
sure the
DR4
is
used
in
the
horizontal
position.
Do
not set
it
on end
or
tilt it
when
using
it.

3.
If
the
DR4
is
moved
from a
cold
location to
a
warm
one, or
if
the temperature has been
raised suddenly, condensation
may
form
inside the
DR4.
If
it
is
impossible
to
avoid
conditions
like
these,
let
the
DR4
sit
for at least
an hour
in
the
new
location
before using
it.
4.
When
setting
up
the
DR4,
make
sure the
ventilation
opening
is
not blocked. Also,
if
using the
DR4
in
a
rack
that
contains other equipment,
make
sure
sufficient ventilation
space
is
assured on
all
sides (approx.
44
mm
of
space between
the
DR4
and any
equipment mounted above
or
below
it
in
the
rack).
