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.

Turning on watchman

1. Create a guard zone (usually 360 degrees) with the guard alarm function.
2. Press the [MENU] key.

period among 5 min, 10 min and 20 min.
5. Press the [ENTER] key.
6. Press the [MENU] key to close the menu.
"WATCHMAN" appears at the top of the screen. The radar transmits for one
minute to check for targets inside the guard zone, and then the CRT shuts off and
the radar goes into standby.
