Question about Thomson M152

In the instruction manual from Thomson: http://www.thomson-av-accessories.eu/webresources/article-documents/00131/man/00131598man_cs_de_el_en_es_fi_fr_hu_it_nl_pl_pt_ro_ru_sk_sv_tr.pdf this one is said to be omnidirectional (not unidirectional). I think something is wrong here.
