Results are presented of 69 spectra of V533 Her obtained during 1981 - 86. Radial velocities show a large scatter above measuring errors, and a binary period is not uniquely determined. Its most probable value is 0.2097774 day. Binary parameters are not critically dependent on the period and are discussed. Emission lines are weak, and show small but unusual phase modulation. Very weak lines of He I, He II, C II, and N III are detected, preferably at some orbital phases.
