I had already read the instructions and knew that the display could be blanked but I could not cycle through the options using the button indicated in the manual or on the remote control.

Eventually I reset the F80 but I was still unable to cycle through the settings for the display. I was on the verge of giving up when I pressed the display button on the remote and for some reason it worked, all’s well that ends well.
