Lock / Unlock Frequencies Procedure
Locking or unlocking of frequencies is only available over the administrator access level.
To mark any frequency as locked/unlocked following steps are required:
1) Press the “See locks” hotkey in the “Freq. Info” dialog. The window, which is shown in Figure
83 appears.
2) To lock a single frequency, press the hotkey “Add Freq.” The “Frequency input” dialog appears
(for further information s. 7.1.2.2), where a frequency, channel number or a Cospas-Sarsat
frequency can be entered. After confirming with “OK” a single frequency is added. It appears
then in the list of locked frequencies as “Start Frequency” as well as “Stop Frequency”.
3) To lock a certain frequency band proceed with step 2), adding the start frequency first. Then by
pressing “Edit Stop” hotkey the last frequency of the to-be -locked band can be entered. In the
same way, the start frequency can be changed using the “Edit Start” hotkey.
4) Unlocking (deleting) of a frequency or a frequency band is accomplished with pressing the
hotkey “Delete Freq”.
Note
Pressing this hotkey will delete the marked frequency immediately without asking for
confirmation!
5) To unlock the whole list of frequencies, use the hotkey “Delete All”.
The difference to deleting the single frequency or frequency band is that for leaving the dialog
the action has to be confirmed with “OK”.
Note
If after deleting all locked frequencies the dialog will be left by pressing “ESC”, the dialog will
be closed without saving any changes. That means, the list will not be deleted and is
accessible again after pressing the hotkey “See locks”.
