Can’t unlock the COROS watch?

- Auto Lock – Hold to Unlock
- Press and hold the Digital Dial or the BACK/LAP button to unlock the display
- Auto Lock – Scroll to Unlock
- Scroll the Digital Dial in any direction until the meter bar reaches top.
- Here’s how to adjust the Auto Lock mode setting:
- Main watch face → System → More Settings → Auto Lock → Standby Mode | Workout Mode → Scroll to Unlock | Hold to Unlock | OFF
- Once Auto Lock mode is activated, the display will automatically lock if:
- Display is idle for 2 minutes in Standby mode
- Display is idle for 10 seconds in Workout mode
