1.27 Watchman
The watchman function periodically transmits the radar for one minute to check
for targets in a guard zone. If it finds change in the zone from the previous
transmission it sounds the aural alarm, cancels the watchman function, and
transmits the radar continuously. This feature is useful when you do not need the
radar’s function continuously but want to be alerted to radar targets in a specific
area.
