Says it has a medical module, what does that mean? does it heal? if so, how???? i'm at work, and bought it late last night, so i'm fuzzy in exact verbage, what is this droid good for?

it allows a medic to heal wounds outside of camps and med centers, but not in cantinas or clone centers

thanks for reply, so having out and within x distance will allow me to heal wounds then..ok, seems worth the 2k i paid...
