Hi.

So I've seen that some models can customize the alert sound for a while now, but never ever be able to use it, and never saw a change-log until now.

My C345 got a new firmware update that was supposed to add a custom alert sound, but after updating, I can't see any new options for this function.

Any idea how to exactly use this?

Nothing in Active Defense > Sound Setting > just like older firmware, only 2 option : Alarm Times / Sound Type [Alert Sound or Promt Tone]

C345 1.0 / 3.0.1 Build 250509 Rel.44121n
