Important Notes About SC999
Primarily intended for operating in
the download mode, logging is not
performed with SC999.
If the machine loses power while
downloading, or if for some other
reason the download does not end
normally, this could damage the
controller board or the PCB targeted
for the download and prevent
subsequent downloading. If this
problem occurs, the damaged PCB
must be replaced.
