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) •
