Mechanics Question

[rockyroad]

Got a quick question...don't have my Fed. mechanics book handy...in Fed. games, do we give a preliminary signal of the foul calls, or just verbalize?? In other words, when I call a foul on "White, 52, push" do I show the push signal at that time...I know at the table we do color, #, show foul signal but don't say anything, but have gone brain dead on the prelim signal at the spot...thanks in advance...
