By exploring spectral data cubes provided by the first two releases of the CALIFA survey, I have calibrated Lick index system for the low-resolution (R=500) CALIFA spectra. I have used the calibrated spectral data for the central regions of 28 common galaxies from the open SDSS database and also long-slit resolved Lick index profiles from our own observations with the reducer SCORPIO-2 of the Russian 6-meter telescope for another 7 galaxies, to derive the relations between the instrumental CALIFA indices and the standard Lick system indices. The first results of the Lick index mapping for 4 early-type CALIFA galaxies are presented; the stellar population mean ages, metallicities, and magnesium-to-iron ratios are traced along the radius for various structure components.
