KX versions belong to the C65X family of phones (to be precise, this version is C651).
There is partial support for these phones, but in a short time they will be fully supported (like language change).
Next versions of software will include features like cloning for C65x phones.
Please be patient, it takes a lot of work and time to get the stable and reliable (no dead phones) solution.
Don't try to use ***/TH4 options on this phone.

PS Take a look and you will find that noone supports any C series phones. There is a good reason for it ;) And there is a good reason why 19.4 WILL support them.
