Power cords and power adapters Use only the power cords and power adapters supplied by the product manufacturer. The power cords shall be safety approved. For Germany, it shall be H05VV-F, 3G, 0.75 mm2, or better. For other countries, the suitable types shall be used accordingly. Never wrap a power cord around a power adapter or other object. Doing so can stress the cord in ways that can cause the cord to fray, crack, or crimp. This can present a safety hazard. Always route power cords so that they will not be walked on, tripped over, or pinched by objects. Protect power cord and power adapters from liquids. For instance, do not leave your power cord or power adapter near sinks, tubs, toilets, or on floors that are cleaned with liquid cleansers. Liquids can cause a short circuit, particularly if the power cord or power adapter has been stressed by misuse. Liquids also can cause gradual corrosion of power cord terminals and/or the connector terminals on a power adapter, which can eventually result in overheating. Always connect power cords and signal cables in the correct order and ensure that all power cord connectors are securely and completely plugged into receptacles. Do not use any power adapter that shows corrosion at the ac input pins or shows signs of overheating (such as deformed plastic) at the ac input or anywhere on the power adapter. Do not use any power cords where the electrical contacts on either end show signs of corrosion or overheating or where the power cord appears to have been damaged in any way. Voltage-selection switch Some computers are equipped with a voltage-selection switch located near the power-cord connection point on the computer. If your computer has a voltage-selection switch, ensure that you set the switch to match the voltage available at your electrical outlet. Setting the voltage-selection switch incorrectly can cause permanent damage to the computer. If your computer does not have a voltage-selection switch, your computer is designed to operate only at the voltage provided in the country or region where the computer was originally purchased. If you relocate your computer to another country, be aware of the following: v If your computer does not have a voltage-selection switch, do not connect the computer to an electrical outlet until you have verified that the voltage provided is the same as it was in the country or region where the computer was originally purchased. v If your computer has a voltage selection switch, do not connect the computer to an electrical outlet until you have verified that the voltage-selection switch is set to match the voltage provided in that country or region. viii User Guide

Power
cords
and
power
adapters
Use
only
the
power
cords
and
power
adapters
supplied
by
the
product
manufacturer.
The
power
cords
shall
be
safety
approved.
For
Germany,
it
shall
be
H05VV-F,
3G,
0.75
mm
2
,
or
better.
For
other
countries,
the
suitable
types
shall
be
used
accordingly.
Never
wrap
a
power
cord
around
a
power
adapter
or
other
object.
Doing
so
can
stress
the
cord
in
ways
that
can
cause
the
cord
to
fray,
crack,
or
crimp.
This
can
present
a
safety
hazard.
Always
route
power
cords
so
that
they
will
not
be
walked
on,

by
objects.
Protect
power
cord
and
power
adapters
from
liquids.
For
instance,
do
not
leave
your
power
cord
or
power
adapter
near
sinks,
tubs,
toilets,
or
on
floors
that
are
cleaned
with
liquid
cleansers.
Liquids
can
cause
a
short
circuit,
particularly
if
the
power
cord
or
power
adapter
has
been
stressed
by
misuse.
Liquids
also
can
cause
gradual
corrosion
of
power
cord
terminals
and/or
the
connector
terminals
on
a
power
adapter,
which
can
eventually
result
in
overheating.
Always
connect
power
cords
and
signal
cables
in
the
correct
order
and
ensure
that
all
power
cord
connectors
are
securely
and
completely
plugged
into
receptacles.
Do
not
use
any
power
adapter
that
shows
corrosion
at
the
ac
input
pins
or
shows
signs
of
overheating
(such
as
deformed
plastic)
at
the
ac
input
or
anywhere
on
the
power
adapter.
Do
not
use
any
power
cords
where
the
electrical
contacts
on
either
end
show
signs
of
corrosion
or

way.
Voltage-selection
switch
Some
computers
are
equipped
with
a
voltage-selection
switch
located
near
the
power-cord
connection
point
on
the
computer.
If
your
computer
has
a
voltage-selection
switch,
ensure
that
you
set
the
switch
to
match
the
voltage
available
at
your
electrical
outlet.
Setting
the
voltage-selection
switch
incorrectly
can
cause
permanent
damage
to
the
computer.
If
your
computer
does
not
have
a
voltage-selection
switch,
your
computer
is
designed
to
operate
only
at
the
voltage
provided
in
the
country
or
region
where
the
computer
was
originally
purchased.
If
you
relocate
your
computer
to
another
country,
be
aware
of
the
following:
v
If
your
computer
does
not
have
a
voltage-selection
switch,
do
not
connect
the
computer
to
an
electrical
outlet
until
you
have
verified
that
the
voltage
provided
is
the
same
as
it
was
in
the
country
or
region
where
the
computer
was
originally
purchased.
v
If
your
computer
has
a
voltage
selection
switch,
do
not
connect
the
computer
to
an
electrical
outlet
until
you
have
verified
that
the
voltage-selection
switch
is
set
to
match
the
voltage
provided
in
that
country
or
region.
