Faac xf 868 radio manual

Hello.
I am looking for instructions like in the title for the radio xf 868 3pin (there is no sw1 button in the receiver)
Faac energy 391 drive

This radio has a short instruction "connect / insert the receiver to the place intended for it on the control panel board".
I have not encountered any other regarding the radio itself.
I advise you to read the 391 drive installation and programming manual.

As far as I remember from the last one I installed, the button is programmed on the control panel - paragraph 8 page 8 of the manual describes the house of each type of remote control that can be saved.
