EBME Forums Forums Maintenance Technical Assistance Arcomedical VP7000 series volumetric pumps

Hello, I just received an Arcomed VP7000, white one, with a large LCD screen.
In other pumps I have seen they have a touch on screen. But this particular one the LCD seems insensitive to touch. I have gone into the configuration mode and not clear how to activate it.
Does anyone know how to do it?
Thank you in advance
