The calculation is performed on the basis of a method which consists in identifying the transmission processes of one electron-hole pair through the dot, where its recombination leads to the emission of an energy $h\\nu$ in one of the reservoirs. This method allows us to get the expressions for the auto-correlator and the cross-correlator noises, which are found to be in full agreement with the ones derived by using more complicated approaches. Upon the application of a voltage bias $V$, we find that the noise derivative, $dS_{\\alpha\\alpha}(\\nu)/dV$, is zero as long as $|eV|
