Nikon Camera F3AF - Manual (Page 23)

Depress the shutter release button
halfway and check both the exposure
and focus displays.
While looking through the viewfinder, depress the shutter re­
lease button halfway to turn on the exposure meter and auto­
focus functions. The LCD indicates the automatically selected
shutter speed to match the aperture set on the lens. As long as
neither +2000 nor “8“ appears in the shutter speed display,
the camera gives the correct exposure. If either indication ap­
pears, adjust the aperture ring on the lens until a desirable
shutter speed is indicated, referring to page 32. The f-number
you have set on the lens is also shown in the aperture-direct-
readout (ADR) window. When both red arrows light up, they indi­
cate that the image is in focus. If the red X appears, refer to
page 26.
