Swann was England's most successful bowler with 3-92
England's Graeme Swann defended the controversial umpire review system after three lbw appeals were referred on the third day of the fourth Test.
The off-spinner collected two wickets via third umpire Daryl Harper as the West Indies finished on 398-5, 202 runs behind England's first-innings score.
Swann said: "While it's there we intend to use it to our advantage.
"In Jamaica we weren't happy with it, we thought were on the rough end of a couple of decisions."
The International Cricket Council (ICC) has sanctioned a trial use of technology during the five-Test series in the Caribbean, although both teams have, at times during the series, appeared confused by its regulations.
Opener Devon Smith and middle-order batsman Brendan Nash were both dismissed via referrals from on-field umpires Aleem Dar and Russell Tiffin off Swann.
And Shivnarine Chanderpaul was controversially given out to a ball which Hawk-eye predicted would have missed the stumps off James Anderson for 70.
Third umpire Harper does not have access to television tools such as Hawk-eye or Snickometer and his role is as an advisor, with the on-field officials authorising the final decision.
