What does it mean if?.......

What does it mean if you shift + 3 for the MPC2000 and nothing shows up on the screen? Cuz I try to bring up the disk page but it didn't show but the rest of the numbers for the pages worked. Any suggestions?

maybe the button is messed up?

what does it mean if i push the on button on my mpc and it turns on?

well also you could try pushing shift + enter and it should be the save page... then push F1 or F2 to load.. i mean this works on the XL so it might help avoid pushing shift+3
