Locking platters on ddj sz

I just upgraded to the ddj sz from the Numark ns6.  One thing that I am trying to figure out is if there is a way to lock the platters on the sz from accidentally touching them which causes the track to stop or skip a beat.  In the ns6 there was a button that would turn off the scratch mode.  I find it that it is very easy to hit platter on the sz when going through tracks or using the effects knob.  Am I missing something or is this an issue I am just going to have to get used to?
