4-Channel Digital Video Recorder
You do not need to install any special software on your personal computer to review the video
clips. Refer to the RAS manual for instructions on how to review video clips you have copied.
NOTE: During Clip Copy, you cannot shut the system down, clear data on the storage
device, or format the storage device.
CAUTION: Do NOT disconnect the USB cable or the power from the external drive while
copying video clips. If the external drive is shut down or the USB cable is disconnected
while copying video clips, THE DVR SYSTEM MAY NOT WORK NORMALLY OR THE
EXTERNAL DRIVE COULD BE DAMAGED, and you will get an error message the next
time you try to copy video clips. You will need to power down the DVR and restart it
to get rid of the error message. Once the file system of the USB hard disk drive has
been corrupted, this error message cannot be dismissed. Even after restarting the DVR
it may automatically restart while preparing to clip copy. You must recover the file
system using the recovery program, or you must reformat the hard disk drive.
