We have measured the magnetoresistance and the Hall effect in the spin-density-wave (SDW) state of (TMTSF)2PF6 down to 2K and in magnetic fields up to 9T in order to gain an additional insight into the nature of the possible subphases in the SDW state. We have found that the temperature dependent magnetoresistance anisotropy changes below 4K ; this change being maximal for the current in the lowest conductivity direction. The Hall resistivity has showed different magnetic field dependencies for 7>4K and T<4K. The resistivity and the Hall resistivity were also investigated as the function of the electric field. The backflow coefficient a does not change below 4K.
