Sabaj A4 - remote control problem

[pranos75]

Hello,

I have a problem with my Sabaj A4 amplifier.
The remote control quickly stopped working.
The seller kindly sent me a second remote but I can't figure out how to pair it.
/ Does anyone know what to do with this remote?

/ Are there any universal remote controls compatible with Sabaj? (After searching on the internet, I haven't found any yet).

Thanks !
