Manual shutter speed adjustment
≥Avoid recording under fluorescent light, mercury light or sodium light because the color and brightness of the playback image may change.
≥If you increase the shutter speed manually, the noise on the screen may increase.
≥You may see vertical lines of light in the playback image of a brightly shining subject or highly reflective subject, but this is not a malfunction.
≥During normal playback, image movement may not look smooth.
≥When recording in an extremely bright place, the screen may change color or flicker. If so adjust the shutter speed manually to [1/60] or [1/100].
