Results of photometric and spectroscopic investigations of the recently discovered eclipsing cataclysmic variable star HBHA 4705-03 are presented .
The emission spectra of the system show broad hydrogen and helium emission lines .
The bright spots with an approximately zero velocity components are found in the Doppler maps for the hydrogen and ionized helium lines .
The disc structure is more prominent in the maps for the neutral helium lines .
The masses of the components ( M _ { WD } = 0.54 \pm 0.10 M _ { \odot } and M _ { RD } = 0.45 \pm 0.05 ~ { } M _ { \odot } ) , and the orbit inclination ( i = 71. ^ { \circ } 8 \pm 0. ^ { \circ } 7 ) were estimated using the radial velocity light curve and the eclipse width .
The modeling of the light curve allows us to evaluate the bright spot parameters and the mass accretion rate ( \dot { M } \approx 2 \cdot 10 ^ { 17 } g s ^ { -1 } ) .
