Not that I have one of these, but the few I've read about are  like garage 
door openers.  Each tank-unit/wrist-unit pair has an ID associated with it.
There is some finite number of ID's.  A wrist unit only listens to
transmissions
that contain its ID.  If you're diving with a buddy, it would make sense to
make sure your units have different ID's.  Perhaps this is configurable by the
the user?   Anyone have one of these beasts?
