With my Time RXS I unclip by moving my heel outward (to the outside away from the bike). No different from the Look Keo I used to have.
There's no adjutment on the cleat per se, only an option for different q-factors (right cleats to left foot, left cleat to right foot) depending how wide you feet are and how far from the crank arms you want them to be. Other than that make sure the cleats have the proper orientation under the shoes. If they are set with too much of an angle you might have to move your heel further to unclip.
