Technical Operation
Canceling (preventing accidental) flash firing
Raise the camera Speedlight detecting lever
with your finger to prevent accidental firing in
sync with other Speedlights. The SB-50DX will
not fire while the lever is in the "up" position.
Wireless Multiple Flash Operation
—continued
Wireless Flash mode
Pressing the SLAVE button on the SB-50DX for
approx. 1 sec. activates the Wireless Flash
mode. When using the SB-50DX as a master
flash unit and attaching it to a camera body
(other than Nikon digital SLR),
appears in
the LCD panel and Monitor pre-flashes (p. 27)
are canceled. Monitor pre-flashes will not be
fired even if the Automatic Balanced Fill-Flash
with TTL Multi-Sensor (p. 25) is selected.
If the SB-50DX is detached as it is,
indication is replaced by
or
and you
can use the SB-50DX as a slave flash unit.
Do not leave the SB-50DX turned on in Wireless Flash mode
When detached from a camera body, the SB-50DX may fire accidentally due to
static electricity or electromagnetic noise if it is kept turned on in Wireless Flash
mode. Make sure to turn the SB-50DX off when not in use.

Speedlight condition
Ready to fire
Fired properly
Both master and slave flash units have
fired at full output and light may have
been insufficient (or too much) for
correct exposure. Change the distance
between Speedlights and subject or
select another aperture and shoot again
(p. 21).
Slave SB-50DX has fired at full output.
The light sensor on the slave SB-50DX
unit could not detect when to stop firing
in sync with the master flash unit. This
was because either the light sensor
window was not directed at the master
flash unit or a strong reflection from the
slave SB-50DX itself or light from
another slave flash unit may have
entered the light sensor window. In this
case, change the direction or position of
the slave SB-50DX unit and/or other
slave flash unit(s), then shoot again.
