How can I lock down a BlackBerry Classic?

Hi All,

My boss has a new BB Classic and he wants to know if I can lock it down so he cannot make changes to the settings.

He somehow manages to change the notifications to "Phone calls only" and is getting annoyed when he does not hear a beep when he gets a text or e-mail.

Without BB Enterprise Server is there a way to lock it down so he cannot change the settings, without a password or the like?

thanks in advance,

idk about all that but you can change what is in the pull down menu from the home screen just move the notifictions from it so its not in the pull down menu
