Being the slug I am I left my manuals in Operations at the airport; however, I do recall reading in the TCAS section a warning about;
Reducing the rate of Climb or Descent the last 1500 feet upon leveloff to preclude nuisance RA's with other Climbing/Descending traffic.
I can't recall the exact FPM climb our manuals say (And your manuals might have something different; there are different versions of the software out there) but I do know that it can make the difference in having an RA or not.
By the way, also in our manual, it says while the displayed range of targets can be up to 40 miles; only 7 miles range is garanteed.
