As indicated by jhpace1 above, this might be a duplication of the question at Soldier teleports himself out of a tank using his mind; discovers he's from the future where the answer was Time War by Lin Carter.
Time War by Lin Carter, 1974, Dell Publishing.
John Lux was an electronic scientist, a level-headed industrialist, an ordinary twentieth-century man--at least he thought he was an ordinary man
...until he discovered he could teleport himself
...until he discovered that forces 200,000 years beyond his time were trying to destroy him
...until he discovered that civilization of the future was being pampered into extinction in a kindergarten world and he was the only man in all eternity who could save it.
But until John discovered how to use his dormant neuro-radionic powers, he was a helpless pawn in a time war--and both he and the planet were doomed...
As you can see, he can teleport himself. He's referred to as having "neuro-radionic powers", and he travels to the future. jhpace1's answer also describes the device being provided with coordinates to the future.
