Wireless multiple flash shooting
Confirming shooting situations in wireless multiple
flash operation
You can confirm wireless multiple flash operation by checking the ready-light on
the SB-900 or the sound monitor during and after shooting.
• When the SB-900 is used as a wireless remote flash unit, you can monitor its operation
by listening to the sound monitor. This function can be activated or canceled using
custom setting (kC-24). This function is set to activate as the default.
• To save battery power, the ready-lights on the remote flash units can be turned
off in the custom setting. The rear ready-light is set to light up and the front
ready-light is set to blink as the default. (kC-24)

Speedlight condition
Ready to fi re
Fired properly
Both the master and remote fl ash units have
fi red at full output but light may have been
insuffi cient for correct exposure. Use a wider
aperture and reshoot.
The light sensor of remote fl ash could not
receive correctly the command light from
master fl ash. The light sensor could not detect
when to stop fi ring in sync with the master
fl ash unit, because a strong refl ection from the
remote fl ash unit itself or light from another
remote fl ash unit may have entered the light
sensor window. Change the direction or
position of the remote fl ash unit and reshoot.
The SB-900's temperature has risen as
a result of the fl ash being fi red multiple
times in quick succession. Wait until the
SB-900 cools down.
The SB-900's temperature has risen to a certain
level and the SB-900 enters protective shutdown
mode. Wait until the SB-900 cools down.
