The remote flash unit light
sensor has failed to receive
the command.
With optical control, this is
because the light sensor
cannot detect when to stop
firing in sync with the master
flash unit, either due to a
reflection from the remote
flash unit itself or light from
another remote flash unit that
may have entered the light
sensor window.
Change the direction or
position of the remote flash
unit and reshoot.
