Problem
Symptoms
Suggested Solutions
System freezes
After being in Freeze mode
for several hours, the
system is not responding
to the FREEZE key, or any
other keyboard inputs.
Need to use the mains
POWER switch on the
rear panel to turn off the
system. The system seems
to be working normally
after restarting.
Update the software
Slow system re-
sponse.
Startup takes too much
time (a 30 minutes’ startup
has encountered by a cus-
tomer). The system is re-
sponding slowly. While
saving images is normal,
reading may take as long as
30 minutes.
Update the software. If problem persists, re-
place the HDD.
