Watchman

The watchman feature transmits the radar for one minute at a specified time interval
(5, 10 or 20 minutes) to monitor the guard zone. If a target is found in the guard zone,
the watchman is cancelled and the radar continues to transmit. This feature helps you
watch for targets in the area you set when you do not continuously require the radar.

zone is active. You can set Watchman when the radar is in transmit state.)
2. Select [Menu] on the menu icon bar to open the main menu.
3. Select the [Radar] - [Watchman] menu.
4. Select a watchman rest interval.
5. Select [Close] to exit the menu.
6. Select [Watchman] from the RotoKey menu to activate the watchman function.
