Manual Managed Descent Speed

I'm trying to manually enter a descent speed for the DES phase of the flight. Unfortunately I can't find documentation on how to enter these number in the MCDU and if I try to enter them in a way that makes sense to me I get an "OUT OF RANGE" error message. You can see that in the attached picture. So does the 'Bus actually support this? And if so, what format does it take to enter it correctly?

Please try entering mach or speed, as written in FCOM.

Not a combination mach/speed.

Entering a speed in knots worked fine. So you fixed my problem, thanks a lot :)
