Similar to the GZK cutoff, the dip is a signature of UHE proton
interaction with Cosmic Microwave Radiation (CMB). It is produced
due electron-positron production in collisions of protons with CMB
photons. The dip is located in energy range 1 - 40 EeV. It is
demonstrated that the dip is very well confirmed by the data of
AGASA, Fly's Eye, Hires and Yakutsk detectors. Since the energy
position of the dip is model-independent it can be used for energy
calibration of the detectors. After this energy calibration the
absolute fluxes, measured by all detectors, coincide well. Based
on the dip and energy-calibrated data of all detectors, the prediction
for the Auger measured spectrum and absolute flux is made for energy
interval 1 - 70 EeV, which includes beginning of the GZK cutoff.
