The Randall-Sundrum (RS) model with a small curvature is considered. The mass spectrum of Kaluza-Klein (KK) gravitons in such a scheme is similar (although not equivalent) to that in a model with one extra dimension in a flat metric. The gravity effects in the processes $e^+e^- \to e^+e^-$ and $e^+e^- \to\mu^+\mu^-$ at the collision energy 1 TeV are presented. Our calculations are based on the previously obtained formula for virtual graviton contributions which takes into account both a discrete character of the mass spectrum and nonzero widths of the KK gravitons.
