  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 $ 0.6\times3.3$ Tesla$\times$meter integral of the
KEDR detector longitudinal magnetic field due to the anti-solenoids
'switched-off'.
