  Particle probe analysis of the Kehagias - Sfetsos black hole spacetime of Ho%
\v{r}ava-Lifshitz gravity is extended to wave probe analysis within the
framework of quantum mechanics. The timelike naked singularity that develops
when $\omega M^{2}<1/2$, is probed with quantum fields obeying Klein-Gordon and
Chandrasekhar-Dirac equations. Quantum field probe of the naked singularity has
revealed that both the spatial part of the wave and the Hamiltonian operators
of Klein-Gordon and Chandrasekhar-Dirac equations are essentially self-adjoint
and thus, the naked singularity in the Kehagias - Sfetsos spacetime become
quantum mechanically non - singular.
