From the CLI:

2. Tell CAS to forget the old fingerprint:

Code Block
sudo /batm/batm-manage terminal-unpair serialno

3. Turn the BATM back on.

Tip

Troubleshooting

Note

On older CAS versions (pre-2021): is your Shared Secret Hash properly set in the Terminal settings?

  • Try resetting it to the default, even if you haven’t changed it recently.

  • This hash is emailed to you after you've confirmed receipt of your BATM.

  • Contact the Support department if you've lost your Shared Secret Hash.

    • The Shared Secret Hash was eliminated in version 20201015.
