Setting the slave mode:
Depending on your camera and ash settings, the master ash may emit more than one burst of light in
quick succession (called a “pre-ash”). Pre-ash is used to help the camera meter and/or focus, and is done
automatically by the camera. If the slave ash is not set correctly, it may be triggered by the pre-ash and re
before the camera’s shutter opens. In order to ensure that the VS-570F res 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 ash 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 ash will re on the rst (or only) burst of light. Use this mode when the master ash
is set to manual.
B. In modes 1 and 2, the slave will ignore either one or two pre-ashes, respectively. Use these modes
when the master ash is set to TTL or automatic modes. Whether the master emits one pre-ash 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 ashes 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-570F as a slave.
