The LED light on the charger illuminates when you start charging your ring. When the light blinks, your ring is charging (but is not fully charged). When the light ceases blinking, the ring is fully charged.

A full charge requires 20–80 minutes of charging time, depending on how often you charge your ring. 

If the LED light does not illuminate:

• Check that the charger cable is connected properly.
• Make sure that the ring is positioned correctly, ensuring good contact between the ring and the dock.
