NOTE: If you change the channel dwell time or change the number of channels
in the scan table, you must recalculate the duration of the preamble,
that is, the channel dwell time multiplied by the number of channels in
the scan table(s) allocated to the HF network.
NOTE: You cannot set a channel dwell time that is lower than the default
value.
