Warning Functions - Nikon Speedlight SB-16 Instruction Manual

Warning functions
In the TTL or non -TTL automatic mode, both the ready-
lights on the fla sh unit and in the camera's viewfinder
blink for 3 seconds after the flash unit fired at its maxi-
mum output , indica ting that the light might have been
insufficient for correct exposure. In this case, check the
subj ect distance and if it is out of the automatic shooting
range, use a wider aperture if possible or move closer to
the subject. Because the voltage of batteries decreases
with use, the guide number might also be reduced slightly.
The flash output of the 88-16 depends on the available
ambient light and the reflectivity of the subject. Note that ,
because of these factors, the ready-light may blink to
indicate that the light output was insufficient for correct
exposure , even if the subject is within the auto shooting
rang e.
Other warnings shown by the ready-light's blinking vary
according to the type of flash unit and the camera in use.
