TAD page changing scale

[ex81]

Hi,

it`s been a while since I realized, that I could not change the scale range of the TAD page using the ADJ rocker key in the upper left corner of the MFCD.

It works when I use the DMS switch or the keyboard commands HOME or END.

 

Because it`s a clickable cockpit I sometimes would like to use the rocker. Any idea why this does not work ?

You need to set MAP to MAN (manual mode) OSB 20.
