first sweep, only the most powerful
stations received will be selected
and locked in. During the next
sweep, the less powerful and during
the third cycle, also the weak

operation will be continued at the
same sensitivity level. If 8 seconds
are exceeded, the radio will revert to
searching only the most powerful
stations.
