Dead Nymi Band
If the screen is blank on the Nymi Band and pressing any button does not wake it up, charge the Nymi Band.
Broken Nymi Band
If a Nymi Band is physically broken, for example, the screen breaks, replace the Nymi Band with a new Nymi Band.
Lost Nymi Band
If a user loses their Nymi Band, deactivate the Nymi Band in the NES Administrator Console, and then assign a new Nymi Band to the user.
When authentication of the Nymi Band fails, the Nymi Band vibrates and displays a retry message.
Cannot Disable Liveness Detection
The Liveness Detection option has been disabled in the active group policy or a user has been assigned to an individual user policy with the liveness detection option disabled, but the Nymi Band continues to check for liveness during authentication.
Fingerprint sensor not working
If you suspect that the fingerprint sensor is broken, clean the fingerprint sensor on the Nymi Band, and then ask the user to attempt authentication again.
Troubleshooting Bluetooth Issues
Bluetooth Low Energy (BLE) communication between the Nymi Band and the user terminal requires a BLE radio antenna via Nymi-provided BLED112 adapter. The solution presented in this section cover issues resulting from irregular BLE adapter placement and fluctuations in received signal strength indication (RSSI) values.
