FAQ
Why
do
I
fail
to
log
in
after
the
network
is
restored?
Answer:
After
the
network
is
restored,
it
takes
about
5
to
20
seconds
for
the
system
to
become
normal.
Why
does
the
RAID
5
array
fail
to
be
re
‐
built?
Answer:
The
selected
disk
does
not
match
the
device.
Select
a
disk
with
the
same
brand
and
size
as
the
faulty
disk.
Why
does
the
display
not
respond
when
I
use
the
remote
control
to
operate
the
monitor?
Answer:
The
correct
method
for
using
the
remote
control
is
as
follows:
1.
Before
operating
the
remote
control,
ensure
that
its
battery
with
sufficient
energy
has
been
correctly
installed
in
the
remote
control.
2.
When
using
the
remote
control,
aim
the
infrared
transmitting
end
of
the
remote
control
at
the
infrared
receiving
port
of
the
device
(indicated
by
an
IR
LED
on
the
front
panel
of
the
device).
Then
perform
operations
on
the
remote
control.
If
operations
cannot
be
performed
on
the
remote
control,
continue
with
the
following
step:
3.
Press
Device
on
the
remote
control,
enter
the
remote
control
ID
of
the
device,
and
then
press
OK.
255
is
a
privileged
device
code
for
use
during
device
code
check.
That
is,
if
you
enter
255
during
the
check,
the
check
will
be
successful
no
matter
whether
the
device
code
is
matched.
If
the
device
can
receive
the
command
from
the
remote
control,
the
IR
LED
turns
green
and
makes
a
sound.
Now
you
can
use
the
remote
control
to
operate
the
device.
In
the
whole
process,
the
panel
and
monitor
of
the
device
have
no
prompt
information.
If
the
remote
control
does
not
work,
repeat
the
preceding
process
once
again:
Press
the
Device
button,
enter
the
device
code,
and
then
press
the
OK
button.
If
the
device
cannot
receive
instructions
from
the
remote
control
after
multiple
attempts,
check
whether
the
following
problems
exist:
z
the
positive
and
negative
polarities
of
the
battery
are
inversely
connected;
z
the
battery
is
running
out
of
energy;
z
an
obstacle
exists
between
the
infrared
transmitting
end
of
the
remote
control
and
the
infrared
receiving
port
of
the
device;
z
a
fluorescent
lamp
used
nearby
affects
the
remote
control.
If
the
problems
do
not
exist
but
the
device
still
cannot
be
operated,
contact
the
local
distributor.
Why
is
there
no
image
but
a
blank
screen
displayed
after
a
live
viewing
connection
is
successfully
built?
Answer:
z
Use
a
mainstream
discrete
graphics
ATIX1550
(or
a
later
version)
or
NVIDIAGF7300LE
(or
a
later
version)
with
a
memory
larger
than
256
MB.
The
discrete
graphics
supports
DirectX9.0c.
z
Install
the
latest
driver
on
the
discrete
graphics
and
adjust
the
rate
of
discrete
graphics
to
the
largest
value.
z
Ensure
that
the
color
management
part
is
set
to
the
largest
(32)
bits.
