Corrections

A correction is any change to a published article that alters what it claims. That includes a factual statement revised, a figure or model designation changed, a claim withdrawn because it could not be substantiated, and a dated statement updated after a manufacturer changed its range or its documentation.

It does not include a misspelling put right, a broken link mended, a heading reworded or a paragraph tightened without a change of meaning. Those happen continuously and are not logged.

The test is simple: if a reader who acted on the earlier version would have been misled by it, the change is a correction and it appears below.

Most corrections begin with an email from a reader, and the rest with a routine re-check of an article against its sources. In either case the disputed claim is compared again against the manufacturer’s documentation or the relevant standard.

Where the article was wrong, three things happen: the text is changed; if the change alters the meaning, a dated note goes at the foot of the article; and an entry is added to the record on this page. Where the reader was right, the entry says so.

Where the article was right, the reader receives a reply with the source, and nothing changes. Either way a reader hears back.

Entries are listed newest first. Each gives the date, the article affected and what changed.

No correction has been recorded since the site was first published.

An article on this site is never defended against the manufacturer’s own documentation. If the two disagree about how a piece of equipment behaves, the documentation is treated as correct and the article is amended, whether or not the reader who raised the point turns out to be the one in error.

Firmware conventions, printed addresses and indicator schemes change between model years. A description that was accurate when it was checked can stop being accurate without anyone changing a word of it, which is why every article shows the date it was last compared against source and why this page exists.
