If the protocol contains continuous stages (for alternative workflows), then proceed through each
continuous stage according to the following instructions:
To begin saving acquired images for the selected stage, press <Save> on the control panel.
The system displays a percentage marker below the selected stage indicating the progress of the
continuous capture.
To halt saving acquired images for the selected stage, rotate the knob under [Pause] on the
touch screen or press <Freeze> directly. The percentage stops increasing.
Select [Continue] or press <Freeze> again to continue.
To end the current acquisition, press <Save> on the control panel.
To select another continuous stage, rotate the knob under [Stage XXX] on the touch screen.
Suspending is not allowed under continuous exam.
