  We consider the dipole transitions and the linear and quadratic Stark effect
in the MICZ-Kepler system interpreting as a charge-dyon system. We show, that
while the linear Stark effect in the ground state is proportional to azimuth
quantum number(and to the sign of monopole number), the quadratic Stark effect
in the ground state is independent on the signs of azimuth and monopole
numbers.
