Each time the flash is fi
red,
the SB-104
checks
to
be
sure both flash tubes have fired
normally. If both flash tubes fires abnormally,
the Flash Abnormality lamp blinks after firing.
If the lamp blinks
even
though the SB-104
has fired, one of the two flash tubes
is
defective.
If the shutter is released before the ready-
light goes
on
, the flash will not fire and the
flash abnormality lamp will blink. However,
there is
no
abnormality
in
this case.
