Using the VS-570 as a Wireless TTL Slave

To set the VS-570 as a Sony TTL slave, follow these steps:

1. Make sure the VS-570 is set to Sony TTL slave mode.
2. Press the Mode button repeatedly until the master control screen

appears on the LCD. Use the up or down navigation buttons to select
CL1 or CL2. Make sure to set it to the same mode as the master.

3. Press the Mode button repeatedly until the Sony optical slave screen

appears on the LCD. Use the up or down navigation buttons to cycle
through the slave mode and channel combinations.

A. If the flash is set to CL1, it will cycle through SL1, channels 1–4.
B. If the flash is set to CL2, it will cycle through channel 1, SL1;

channel 1, SL2; channel 2, SL1; channel 2, SL2; and so on.

4. If desired, adjust the flash coverage angle by pressing the Zoom

button repeatedly.

5. 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.

Note:

Your flash must be on the Sony optical slave screen in order for it to operate as a TTL slave (Example 3).

Do not navigate away from this screen while operating the VS-570 in this mode.
