Compact display click stop

[falcon71]

Hello, the manual states:

BRT PFD dimmer control – adjusts the intensity of the associated upper DU. A click stop is provided at the
COMPACT position. When set to this position, the upper DU is blanked and the lower DU shows a combined
PFD/ND or COMPACT format.

How can I trigger the click stop? I'm using the legacy control scheme and I tried all sort of clicks, but I can only set it to the minimum brightness. The upper DU appears blank, but the lower DU does not change to the compact mode:

The same problems occurs when I turn down brightness on the lower DU.

Thanks for raising this. The compact PFD is not simulated in the RJ Professional, so we will update the manual in the next RJ Professional update to reflect this.
