sounds (if active), the target flashes, and the message "TARGET ALARM" flashes in
the status bar. Tap the status bar to silence the aural alarm and stop the flashing mes-
sage. The message remains in the status bar and the target continues to flash until
the target leaves the guard zone or the alarm is deactivated.
You can mute the audio alarm by turning off [Alarm Sound] in the [Settings]→[Alarm]
menu. (see subsection 2.10.8).
