F89, when you are on, it should only take a single click-press hold to lock max on. Double click-press hold will get you there from off, momentary or locked depending on whether you have pseudo momentary activated.
BTW, thanks for being relentless about the F89HG, it's my HG now too! :twothumbs
EDIT: Wait, what? I just checked the manual online, and it says it takes a double click-press hold to lock on preset A. Now I have to check this on my new light. I absolutely know it has always been one click-press hold back before the Novatac days. Don't understand why that would change.
Hmm... Novatac and Legacy manuals show click-press to lock A, Ultimate and current manuals show double click-press. Can't wait to check this, am I just that used to my Novatac lights?
