D The Flash-Ready Indicator
When the flash fires at full power, the flash-indicator in the camera
viewfinder will flash to warn that the resulting photograph may be
underexposed.
Note that the flash-ready indicators on optional flash
units will not display this warning when 1/320 s (Auto FP) is selected.
