Page 9: Summary
The RVL469 contains functions of the RVL470 and is therefore integrated in the present Basic Documentation. But only the section “RVL469” refers to the specific functionality of the RVL469 (functions that differ from those of the RVL470). In all the other chapters and sections, the RVL469 will not be specifically mentioned. -
