all application software that is using the OCTA-CAPTURE, switch o the
OCTA-CAPTURE’s power, then turn it on again.
p. 68
Could other software programs be running?
Close software that you’re not using.
If the window of a Windows program has been closed but it is still shown in the
taskbar, that program is still running. Close all unneeded software that’s shown
in the taskbar.
