It is likely that your Smart Adaptor battery is flat and will need recharging.

To charge your Smart Adaptor:

1. Remove the USB Port Cover from the Smart Adaptor and place it somewhere safe.

2. Using the supplied USB Charging Cable, charge the Smart Adaptor from a wall charger, laptop or other low-energy charging device that compiles with the IEC 62368 1 standard.

3. The LED will illuminate red to indicate it is in charging mode.

4. When fully charged the red LED light will switch off.

5. Unplug the USB charging cable and remember to cover the USB Port with the USB Port Cover, for protection.
