A possibility to study final state radiation near the \pi ⁺\pi ^- threshold region at the \Phi -factory DA\Phi NE is discussed. The dependence on the final state radiation model is tested by a Monte Carlo event generator that includes the contribution of the direct \phi \to \pi ⁺\pi ^-\gamma decay, the double-resonance \phi \to \rho \gamma \to \pi ⁺\pi ^-\gamma contribution and ``pure'' final state radiation both in the framework of the sQED model and in the Resonance Perturbation Theory. Finally, a model-independent way to study final state radiation is proposed.
