Ask a question and Echo answers from the documents listed at the foot of this page, quoting the section and page it came from. If the answer is not in those documents, it says so rather than offering a guess.
Echo answers from these and nothing else. Anything outside them — another operator's instructions, your roster, a local arrangement — it declines rather than answering from somewhere else. Everything it does answer carries the document, section and page, so it can be checked against the document itself before it is relied on.
