Or...you can load the BeoApp, do a factory reset or cancel/delete the calibrations. It will be similar to this chain of commands on the BeoApp:- Select Product >> Product setting >> Configure >> Preset >> Select a preset >> Room Compensation >>  Select model >> Delete. Im not sure why you would want to do that as it add so much to the performance of the loudspeaker.

This can be helpful if you would like to measure the acoustic response of the room without the adjustments of the speakers room compensation. I had a acoustic engineer at my house and we measured both, with and without B&O room compensation. Quite intersting by the way. Helped to understand the room and how to tweak the EQ on top of the room compensation to get the max out of the speakers. But of course, this is not the usual use case...

Thank you so much for the precious info. Beside the fact that my curiosity leads me to wanting to know what they sound like without it, the calibration performed by the installer was less that optimal to say the least. He was holding the mic with his hand throughout the entire process, and with his body standing between or near the mic as he was handling it. I know I can do a better job than that when I’ll get my hands on the microphone which I don’t have as now.   Thanks again.

My BL50 sound far far more better with Room Eq (my room is treated with GIK free standing bass traps and my source is Wattson Madison streamer DAC / rca ) Edit : I am sorry I just wrote the contrary of my thoughts, of course ROOM compensation help a lot but it’s icing on the cake after a good (perfect?) speaker placement and a room passive treatment

Ok… I did indeed reset ? the room calibration and I regret it already. For some reasons the volume is not as high as it was, despite it is set to max-90, and the tweeter assembly does not recess as It did earlier in just one minute. I’m confused thou: Is there  a section with advanced settings as, starting a new calibration? Or set the timer for the standby? Am I missing a portion of advanced software? I’d love more enlightening. Thank you again for reading this.

First, you will need a USB microphone. Read the manual: https://bangolufsenassistentgohe.blob.core.windows.net/manuals/SPEAKERS/BEOLAB_50/beolab_50_technical_sound_guide.pdf#page14 Then watch: https://www.tonmeister.ca/wordpress/2017/04/19/bo-tech-beolab-90-how-to-set-up-active-room-calibration/ Although this video is for the 90s, the process is the same.

Ok. I panicked for a few moments there… I’ll start with printing the manual. Thank you so much, I appreciated it.
