When it may be normal
This light may be normal if the device recently powered on, is pairing, is charging, is updating, is connecting, or is completing a setup step. If the light changes after a few minutes and the device works normally, it may not require further action.
When to contact support
Contact the manufacturer or a qualified professional if the light stays on after basic checks, appears with warning sounds, appears with heat or burning smells, affects a safety device, or comes back repeatedly after restarting.
