If you press the button matching your press setting, you’ll know you’ve sent an alert when you feel the Tag vibrate, and your network will get an alert. Other presses will be ignored.
You can deactivate the alert as soon as you realize it. Simply go to the Home screen in the Wearsafe App, slide the alert button to the OFF position, and enter your birthday. Your network will immediately get your “Closed Alert” notification as well.
