There are three control states in
Bandscan
page – Span control, Marker control and Parameter
control. The states can be identified by the labels of the soft buttons. If the labels appear as shown
on the picture below, the page is in Marker control state.
For example: When the following menu is selected pressing [SB3] will change the screen from
Marker
to
Span
control and vice-versa. All Soft buttons labels will change according to the sub-
menu. The control state of the page will change upon every [SB3] pressing.
Pressing the [OK] button either in Marker or Span control state will make transition to Parameter
control state. The screen will be visible until the [OK]button is pressed again or the timeout of 2
seconds elapses.
