Dielectric, electrooptic and pyroelectric properties of unknown SmX* phase of (S)-(1-propyl-oxycarbonyl) ethyl 4(dodecyloxythiobenzyloxy) benzoate are studied. Low frequency dielectric studies performed with a 10micrometers EHC cell show that this SmX* phase exhibits an induced Goldstone mode dielectric spectrum. The spectrum is a single Debye-Type process with the relaxation time of the order of 10-5 s. The intensity of the spectrum increases non- linearly with the bias field strength. Studies of pyroelectric coefficient in the vicinity SmA*-SmX* transition show, that the SmX* phase is not a typical ferroelectric or antiferroelectric phase, and that the character of the transition depends on the field strength applied.
