Hiya, Thanks for the review. Belatedly responding to your various mails as I get the -07 ready.

Even when mounted on a mains-powered bit of equipment, sometimes these devices run on their own battery.

Sorry, not sure what you mean. Figure 3 and that text were contributed by folks who know more than me about that, but if you'd like to suggest specific text I'd be happy to make a change, if there are no objections on the list.
