I think what Dumbledore meant was,"You must not be seen 
using the Time Turner for an unauthorized purpose." 

It was perfectly all right for Hermione to be seen by the other 
students in the classes she was doubling up on, though she 
wasn't supposed to tell them how she was doing it. McGonagall 
knew she had a time-turner, and I think the rest of the staff 
probably did too.

 If anyone had seen her helping Sirius or Buckbeak to escape, of 
course she'd have been in trouble anyway, but using the Time 
Turner for such a purpose would have made it much worse.
Hermione didn't have permission to use the Time Turner for 
anything but classes, so using it after school hours for any 
reason  would be a no-no. Harry, of course, didn't have 
permission to use the TT at all.
