Nikon and Canon TTL Slave Modes
When setting the VS-570 as a wireless TTL slave for Nikon and Canon TTL systems, you can configure the TTL
mode, group, channel, and flash coverage angle (zoom).
To set the VS-570 as a Nikon or Canon TTL slave, follow these steps:
1. Make sure the VS-570 is set to Nikon or Canon TTL slave mode.
2. Use the up or down navigation buttons to select the channel and group.
The flash will cycle through channel 1, groups A through C; then channel
2, groups A through C; and so on.
A. When using a single slave flash, set it to the same group and
channel as the master.
B. When using multiple slave flashes, select the same group and channel for all units in the same
light position.
3. If desired, adjust the flash coverage angle by pressing the Zoom button repeatedly.
4. Make sure that the red light on the front of the VS-570 is blinking. This indicates that the unit is ready to
fire in wireless TTL slave mode.
