Need a bit of help here.

SX200 with superconsole 1000

I'm trying to set up the abbreviated Dialing.

I follow the instructins to set the dialing.
It seems to save fine in the console.
But how do we use it?

Am i wrong here:
Set the dialed number (555-5555) to 355
Index number to 355 = 955555555
save

Extentions should be able to press 355 and it should dial 555-5555 right?
