AB  - We have investigated the dynamic critical behavior of the two-dimensional 
      Z(5)-symmetric spin model by using short-time Monte Carlo (MC) simulations. We 
      have obtained estimates of some critical points in its rich phase diagram and 
      included, among the usual critical lines the study of first-order (weak) 
      transition by looking into the order-disorder phase transition. In addition, we 
      also investigated the soft-disorder phase transition by considering empiric 
      methods. A study of the behavior of beta/nuz along the self-dual critical line has 
      been performed and special attention has been devoted to the critical bifurcation 
      point, or Fateev-Zamolodchikov (FZ) point. First, by using a refinement method 
      and taking into account simulations out of equilibrium, we were able to localize 
      parameters of this point. In a second part of our study, we turned our attention 
      to the behavior of the model at the early stage of its time evolution in order to 
      find the dynamic critical exponent z as well as the static critical exponents beta 
      and nu of the FZ point on square lattices. The values of the static critical 
      exponents and parameters are in good agreement with the exact results, and the 
      dynamic critical exponent z approximately 2.28 very close to the four-state Potts model 
      (z approximately 2.29).
