Schematic Digital Mixer RFC type M18

[Bektronics]

Hello dear audio friends.

I am feverishly looking for the full electronic schematic (not a block diagram) of the RCF type M18 digital audio mixer.
The device does not make a WIFI connection with my Apple tablet and yet I have already installed the recent app on it.
I suspect that there is a problem in the mixer itself with the WIFI card and of course I would like to see this on an extensive schedule before opening the device.
Thanks in advance if anyone can help me with this schematic.
Of course, all information about this digital mixer and possibly references to other websites regarding this is also welcome.

Kind regards.
Andy.
