Note: The Hop Table Version must be set to 0 (Entire Band) when using Frequency Zones. If another Hop Table
Version were to be selected, the limitations of that selection would be applied to the hopping pattern as well.
Warning: In order to stay within
FCC regulations it is required
that a minimum of 50 separate
frequency channels be used within
a hop pattern. This means that a
minimum of 7 frequency zones is
required for legal communications.
