cords
and
power
adapters
DANGER
Use
only
the
power
cords
and
power
adapters
supplied
by
the
product
manufacturer.
The
power
cord
and
power
adapter
are
intended
for
use
with
this
product
only.
They
should
never
be
used
with
any
other
product.
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
or
any
other
cables
so
that
they
will
not
be
walked
on,
tripped
over,
or
pinched
by
objects.
Protect
power
cords
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.
