Using Your Vs-570 As A Wireless Manual Flash - Bolt vs-570s User Manual

automatically by the camera. If the slave flash is not set correctly, it may be triggered by the pre-flash and fire
before the camera's shutter opens. In order to ensure that the VS-570 fires at the correct time, there are three
different slave modes available: modes 0, 1, and 2. To select the correct slave mode, follow these steps:
1. Make sure the flash is in Slave mode.
2. Press the Up and Down buttons to cycle through the slave mode options on the LCD.
A. In mode 0, the flash will fire on the first (or only) burst of light. Use this mode when the master flash
is set to manual.
B. In modes 1 and 2, the slave will ignore either one or
two pre-flashes, respectively. Use these modes when
the master flash is set to TTL or automatic modes.
Whether the master emits one pre-flash or two will
depend on the camera and settings—always take a
test exposure to ensure that the slave is set correctly.
Important! Some cameras, when set to red-eye reduction, will emit a series of quick flashes lasting a second
or more. This may not work properly with any slave mode. We suggest you avoid using red-eye reduction
when using the VS-570 as a slave.
