The buttons change by maker. The concepts don't.

20 lessons across six study days, a ten-question check closing every lesson — 200 questions over the concept layer that transfers to every console: what makes an ECDIS legal, ENC versus RNC and how far to trust the survey (CATZOC), the safety contour and the settings the groundings turn on, alarms and updates, the sensors and position integrity behind the symbol, route monitoring and the alarms list, the operator tools and radar/AIS overlays, familiarisation, and reading the display. Pass a check (8 of 10) to mark a lesson complete; progress is saved on this device. The safety-contour workbench is built into day four.
