No use in overland, whatever it is, among other things, that only a manual scan must be triggered when changing the coverage area.
MissLungen I find the dial, which is much too easy and no screening has, so you always overshoots's goal.
Also, the lower of the two display lines is permanently assigned when the keypad lock from the "KeyLock On" message, so that the additional information is no longer visible. Here the firmware developer has apparently had a bad day, it had fully passed, display the lock status shortly when pressing a button, etc.
For me, the operation via the imprecise dial was decisive for the revocation, but that's for a matter of taste, and on the other hand there are unfortunately no really convincing alternative :(
