ARS-2021D/2021DS Manual

7.4 About Buttons

If you press any one of the four buttons on the panel, but there is no response, it is
perhaps that the button cannot function well. Please inspect the jumper setting.

7.5 About DVD Writer Not Readable

After copying if the DVD writer is unreadable, please use Compare to examine, or
get another DVD-ROM to test.

7.6 About High Failure Rate

If the failure rate of copying is high, please do the following things to improve.
l
Lower the speed of DVD writer
l
Inspect if the blank disk's quality is bad.
l
Update the firmware.
l
Inspect the DVD writer's maximum writing speed. If the speed is over 24X,
copy the data to a hard disk first, and then transmit to DVD.

7.7 About Firmware Update

If you cannot update the firmware, please inspect the BIOS program. Perhaps you
have downloaded a wrong program, or let a zipped file be written into DVD. The
zipped file should be unzipped first.
Failure in firmware update may cause ARS-2021D/2021DS to fail in booting. Under
the circumstance, please return the control board to ACARD for repair.
