How do I set notification volume back on when I leave a gps area defined by tasker on android?

I have a profile for college on my Droid incredible that sets my phone to vibrate, I have a gps defined area that triggers the event. How do I set the volume when I leave the gps area. I couldn't find a clear answer on the forums|||http://androidforums.com/android-applica鈥?/a>
