Watchman

The watchman function transmits every 5, 10 or 20 minutes (selectable on menu) for
one minute to check for targets in a guard zone. If a target is found in the zone, the
watchman is cancelled and the radar continues to transmit. If there are no targets in
the zone, the radar goes into stand-by for the number of minutes set on the menu. This
feature helps you watch for targets in the area you set when you do not continuously
require the radar.
