Optical Slave Triggering Mode - Bolt VB-11 User Manual

Optical Slave Triggering Mode

Optical slave triggering mode sets your flash to fire wirelessly whenever it detects a signal from a master
flash.
The VB-Series bulb flashes have two slave settings: S1 Mode sets the flash to fire in sync when the master
flash is triggered, while S2 Mode allows the flash unit to ignore a single "preflash" from the master and only
fire in response to the main flash from the master unit.
To use the optical slave triggering mode, press the Mode button until S1 or S2 is displayed on the LCD screen.
