Infini RF temperature?

Is it in the hands of the operator to make sure infini RF uses temperature that doesn't denature collagen or Lutronic sets safe temperature limits that can't be overdone? Is 3.5 mm safe for everyone on body (thighs/arms/ab) or it's up to the operator to determine the needle length ? Can operator's inadequate training do harm to infinity RF receipient ?
