The lighter, ‘ding’ bell rings when you set up, amend or stop your timer within the time allocated. Contacts can turn this off, if you are receiving timer alerts late at night while asleep, or when you are overseas in a different time zone.
Contacts will still receive an alert bell if you are overdue, and the loud Siren will go if the timer is escalated into Alert Mode, or you press the SOS button for immediate help.
To turn off the alert bell when you set up timers or stop a timer, go to: Settings > Profile > Edit. Then toggle on the Mute sound for level 1 bells.
