d. Dual flash operation with digital cameras

There are different ways of operating two strobes with a digital camera. It is very important to note the information below to achieve perfect functionality without damaging your camera. Please read the following information very carefully!

IMPORTANT - FOR CANON USERS

E-TTL use with CANON cameras requires S6 sockets on the flash and the camera. (with all the 6 wires connected to both strobes). Set both units to TTL mode. When the unit is connected to the camera, it automatically detects the camera transmission protocol. This is an easy method of using two flash devices in E-TTL or in manual mode.

If you want to shoot only one flash, just switch off the unused flash device.
