4. Operating Instructions
Figure 4.29. After an annotation is created, the multifunction indicator at the top of the
screen displays the name of the currently selected annotation.
To save annotations, go to SCAN → Annotations → Save Changes. If annotations were made to
an unsaved trace, a prompt for a name to save the trace with will appear and the trace will be
saved with the annotations. If annotations were made to a previously saved trace, Save Changes
will save the annotations to the trace file.
Stored traces with annotations applied can be loaded back on-screen like any other saved trace.
See Section 4.9.4 for information on loading traces.
To toggle off annotations on-screen, go to SCAN → Annotations and press Annotations On so that
it now says Annotations Off.

keyboard, or use a USB keyboard.
