>>3814740The FX-3 has a "check exposure" button on the back of it. The exposure adjustment LEDs will light up as long as the button is kept pressed. Once you let go, it switches off.
Unrelated, I tried scanning again with the broken scanner again because it's the last thing to do before losing total sanity when you can't really photograph much because of the abysmal weather. The results are not terrible where the scanner isn't clicking.
