important
notices
Operating
environment
The
optimal
environment
in
which
to
use
your
computer
is
10°C-35°C
(50°F-95°F)
with
humidity
ranging
between
35%
and
80%.
If
your
computer
is
stored
or
transported
in
temperatures
less
than
10°C
(50°F),
allow
the
cold
computer
to
rise
slowly
to
an
optimal
operating
temperature
of
10°C-35°C
(50°F-95°F)
before
use.
This
process
could
take
two
hours
in
extreme
conditions.
Failure
to
allow
your
computer
to
rise
to
an
optimal
operating
temperature
before
use
could
result
in
irreparable
damage
to
your
computer.
If
possible,
place
your
computer
in
a
well-ventilated
and
dry
area
without
direct
exposure
to
sunshine.
Keep
electrical
appliances
such
as
an
electric
fan,
radio,
high-powered
speakers,
air
conditioner,
and
microwave
oven
away
from
your
computer
because
the
strong
magnetic
fields
generated
by
these
appliances
can
damage
the
monitor
and
data
on
the
hard
disk
drive.
Do
not
place
any
beverages
on
top
of
or
beside
the
computer
or
other
attached
devices.
If
liquid
is
spilled
on
or
in
the
computer
or
an
attached
device,
a
short
circuit
or
other
damage
might
occur.
Do
not
eat
or
smoke
over
your
keyboard.
Particles
that
fall
into
your
keyboard
can
cause
damage.
Static
electricity
prevention
Static
electricity,
although
harmless
to
you,
can
seriously
damage
computer
components
and
options.
Improper
handling
of
static-sensitive
parts
can
cause
damage
to
the
part.
When
you
unpack
an
option
or
CRU,
do
not
open
the
static-protective
package
containing
the
part
until
the
instructions
direct
you
to
install
it.
When
you
handle
options
or
CRUs,
or
perform
any
work
inside
the
computer,
take
the
following
precautions
to
avoid
static-electricity
damage:
v
Limit
your
movement.
Movement
can
cause
static
electricity
to
build
up
around
you.
v
Always
handle
components
carefully.
Handle
adapters,
memory
modules,
and
other
circuit
boards
by
the
edges.
Never
touch
exposed
circuitry.
