Abstract. Consider the 1D Schroedinger equation y''+Vy=Ey with
potential V bounded by V(x) < C(1+x)^{c}.
We prove that the solutions y satisfy the WKB asymptotic
formulae off a set of energies E of Hausdorff dimension
\le 2(1c). This gives restrictions on the structure of possible
embedded singular spectrum.
