Please don't tell people that you have anything on anyform of TCAS/collision avoidance tool.
In the grand scale of things it means nothing to either controllers or other pilots. Its only when you can see the traffic that the controller can deem you are self seperating and don't require updates. So yes use it so you know which sector it shoud be in for trying pick it up. But until you have it with the mark one eyeball nobody can presume that you really do have the traffic.
