I want to lock the ring volume +/- key. Even after key board locked, keys are working. My model no is T19. We don't have any auto-provisioning server.

Hi,

May I know what's your current firmware version of t19?
We optimized this function on our new V81.110 version, with this version, you can lock the ring volume +/- key as long as the key board locked.

Anything I can help, freely to let me know.

Regards,
Travis
