• Full specificationsPage

  Every published figure for SonaVue, Elevate and TravelerAI, each with the document it comes from and the date it was fixed. Generated from our fact registry rather than retyped, so it cannot drift from the manuals.

The controlled documents: full specifications, Declaration of Conformity, FCC ID and certificate numbers, in the thirteen languages printed. Where a manual and a marketing document differ, the manual is authoritative. Manuals printed before the rename refer to the app as AI Cool; it is now Ear Dance.
