Uniden UH-057 - Manual (Page 19)

When a priority channel is selected and scan is activated,
the radio will monitor the prioritised channel regularly for
activity while scanning.
While scanning, if a signal is received on the priority channel
the radio will stay on that channel as long as the signal is
present. Otherwise, priority scanning resumes after 3
seconds.
However, if scanning stops on a channel which is not a
priority channel, the radio will continue on checking regularly
the priority channel for activity while monitoring the current
active channel.
