You can set a screen lock for your RunIQ by tapping Settings > Personalization > Screen lock.
The default option is None, but you can choose to unlock your RunIQ screen with a Pattern, PIN or Password. Once you set a screen lock you will be required to enter the Pattern, PIN or Password when you wake your RunIQ.
If you forget your Pattern, PIN or Password, you will be offered the option to Disconnect and Reset after your ninth failed attempt.
Choosing Disconnect and Reset will erase all of your data and reset your RunIQ to its original factory settings. However, you can pair your RunIQ again once it restarts.
