[ CLEAR MRKR N]
Menu F5-2: Clears a defined marker. When a marker is cleared it is turned off, its defined fre-
quency is erased, and it becomes an undefined marker. When this softkey is pressed, the entry
area of the display will present a prompt to enter the number of the marker that it is desired to
clear. The frequency of a cleared marker can not be recalled.
[
CLEAR ALL MRKRS]
Menu F5-2: Clears all the markers. When the markers are cleared they are turned off, the fre-
quencies that were defined for them are erased, and they become undefined markers.
Another softkey menu will be presented giving you the choice to either clear all markers or to
abort. When the CLR ALL MRKRS softkey is pressed again, all markers will be cleared. The
entry area of the display will indicate that the markers have been cleared, and the routine will
return to the DEFINE MRKR N menu (F5).
If the [ ABORT CLEAR ] softkey were pressed, the routine would return directly to the DEFINE
MRKR N softkey menu (F5). No Markers would be affected by this action.

the entry channel. If the cursor is inactive pressing this softkey will activate the cursor, place it at its
last frequency position, and then change the reference level.
NOTE:
The frequency of a cleared marker can not be recalled.
