3.5.1 Selecting Parameters
Many parameter settings have a list of options from which to choose. Dialogue level, for
example, can be set to any number between –1 and –31. In these cases, the selected or active
option is displayed without a flashing cursor.
If the cursor is flashing after an option value, that option is not currently selected. Press
Enter to select it. Pressing Esc at an option with the flashing cursor displayed returns the
display to the selected value.
