Fault code appears on the Nymi Band

When a Nymi Band experiences an issue from which it cannot automatically recover, a fault condition appears on the Nymi Band screen.

The following figure provide an example of the Nymi Band screen with a fault condition.

Figure 1. Nymi Band Screen with a Fault Condition

A fault condition contains two parts on two separate lines:

  • Hexidecimal fault code
  • Decimal condition line number

If a fault condition appears on the Nymi Band, in many cases you can recover the Nymi Band by performing the following step:

  • Put the Nymi Band on the charger.
  • Press and hold the top button for about 10-15 seconds.

If you can recover the Nymi Band, the screen goes black, and then the boot sequence messages appear.

The following table provides you with information about the meaning of each fault code and the next step action.
