In this paper we show a procedure how to determine M_1, Φ_{M_1}, M_2, μ, Φ_μ and \tanβeven in the case when only light charginos \tildeχ^{\pm}_1 and neutralinos \tildeχ^0_1, \tildeχ^0_2 would be accessible at the first stage of a future Linear Collider with polarized beams.5 pages, 5 figures; Talk given at SUSY02, the 10th International Conference on Supersymmetry and Unification of Fundamental Interactions, June 17-23, 2002, DESY HamburgHigh Energy Physics - Phenomenologytext
