Hi, All, To tell if the lights are on, flip it to Inverse mode and wave the = camera around. If the array vibrates, then the lights are on. Telling if there are stains on clothing is a little trickier. Start in = normal mode with the camera on the clothing. While running the camera = back and forth, vary the threshold until you can determine a pattern = like stripes or plaid. If you can detect a change in the pattern, = chances are there is a stain. This gets really hard to do if the = clothing has designs or writing. It's fun to read the writing, though.
