How do you turn off parental restrictions on PS3 network on a sub account?

I have gone to security settings and turned them off and on sub account management it only lets you change chat settings and money settings|||Settings%26gt;Security Settings%26gt;Parental Control





Not sure exaclty because I switched mine off ages ago but is something around there. I think have to change the level to the lowest which is 1. I think anyway something like that.|||You can't on a sub account. Only the primary account can change the parental settings. Otherwise there would be no point.
