be
prepared
to
give
as much information as
possible
of
your system,
environment,
and the

When? How

Please
Note:
Since this
product supports Region Playback
Control Phase
II,
a certain MPEG decoder card or
Software without
regional
code
setting may
cause this drive not to read DVD-ROM discs. This Drive enables
you
to
change
the
regional
code
up
to 5 times.
Read
Speed
Control for CD-R Data CD
The basic default
reading speed
for CD-R disc media in this drive is 40X. The Read
Speed
Control will allow
you
to select the maximum read
speed (52X)
for CD-R
media,
simply by pressing
the
eject
button. Note that
this function is
only
available with a CD-R data disc. To enable 52X CD-R read
speed,
follow the chart below:
Flow Chart

Tray

Operation
User instruction
(Push Eject
/
button)
(Put
CD-R disc on
Tray)
(Push
and hold the
eject
button for more than 3
seconds)
The LED indicator turns on for 3 seconds. The 52X maximum read
speed
for this CD-R disc has been enabled. The Read
Speed
Control will allow
you
to select the 48X maximum read
speed
for CD-RW Data CD.
Ejecting
this disc or
turning
off the PC will disable the 52X maximum read
speed
function. The drive will default back to the 40X CD-R read
speed.
CAUTION:
The
quality
of CD-R data disc varies
significantly
from brand to brand
(or brandless),
as well as disc condition used over time. A disc that is
poorly
balanced
or that
may
have cracks in it
greatly
increases the chance of disc failure or disc shatter when
being
read back at
speeds higher
than
40X,
possibly causing
damage
to the drive.
Closely inspect
discs
you plan
to use in the drive for
any
abnormalities or cracks. If
you
hear
strange
noise or sounds from the drive
during operation,
this could be a
sign
of an unbalanced or
damaged
disc and it should be removed
immediately.
LG Electronics does not
warranty
drive
damage
caused
by faulty
or shattered discs.
