High precision photometry gathered from Kepler database and radial velocity measurements of the HV Cnc system found in the literature were simultaneously analyzed by the Wilson-Devinney (WD) code to better understand system parameters. Some physical quantities needed by the WD code in iterations, such as limb darkening coefficients, Kurucz's model atmospheres, and blackbody approach were considered by using precise transmission curves of each Kepler channel. Therefore, we obtained a set of revised system parameters relative to the previous solution of Gokay et al. (2013) in which the results were based on the photometry of 2MASS archival data. In the present solution, we recognized a low amplitude (Delta m(kepler) similar to 0.(m)001) brightening at the primary quadrature of the light curve. This excess light is modelled by considering a combination of ellipsoidality, reflection, and Doppler beaming effects. Consequently, we propose the system as a new candidate of Doppler beaming binary.
