Still having this problem. When asked I activate the on switch in the pedestal and then in the overhead. Still keeps saying Radio Management panel.

Are you doing both left and right panels ON , on pedestals and then ON on top right on Overhead.  Mine works,if I do all three,  but I admit on the first flight I had the problem as the old Airbus only had to do the righthand radio panel On, to clear the checklist
