flashes, and the message "TARGET ALARM" flashes in the status bar. Tap the status
bar to silence the aural alarm and stop the flashing message. The message remains
in the status bar and the target continues to flash until the target leaves the guard zone

menu. (see paragraph 2.10.7).

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 canceled 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.
