The harmonic analysis performed for the light curves of 0716+714 from 2002-2010 in radio and optical wave bands revealed the presence of an apparent periodical component in the flux variations. The period of the radio light curve is nearly 3.6 years, and coincides within the errors with the period of the optical light curve (nearly 3.4 years). The duration of the flares is approximately the same in radio and optical ranges, and it is about 100-150 days.
