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
Fig. 78 appears.
2) To lock a single frequency, press the hotkey “Add Freq.” The “Frequency input” dialog
appears (for further information s. 6.1.2.2), 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”.
