A method proposed to preserve the electron beam polarization at the VEPP-4M collider during acceleration with crossing the integer (imperfection) spin resonance at energy E=1763 MeV has been successfully applied. It is based on full decompensation of the $ 0.6times3.3$ Tesla$times$meter integral of the KEDR detector longitudinal magnetic field due to the anti-solenoids switched-off.
