Dry the band first
Do not place a wet device on the charger. Dry the band and charging surfaces fully before troubleshooting.

Charging troubleshooting
Intermittent charging is often caused by seating, contamination or a weak power connection. Work through these checks before assuming the band has failed.

Clean the charging surfaces
Use a soft dry cloth to remove sweat, lotion or debris. Do not use abrasive tools on the contacts.
Reseat the band
Lift ARC from the dock and place it back in the intended orientation, making sure the sensor is resting flat.
Check the cable and power source
Reconnect the cable at both ends and try another supported USB power source if the connection still appears intermittent.
Inspect for damage
Stop using visibly damaged charging hardware. Contact support for guidance rather than improvising a repair.
Persistent failure
If ARC still does not charge, contact support with the order number and a description of the troubleshooting already completed.
