As for the setting procedure, refer to the slave Speedlite’s instruction manual. Check the communication channel. If the ST-E2 and slave unit(s) are set to a different channel, set them all to the same channel (p.7). Position the camera and Speedlites as desired.
Do not place any obstacles between the ST-E2 and slave unit(s). Obstacles can block the transmission of wireless signals. Make sure the ST-E2’s flash ratio control lamp is off. If the flash ratio control lamp is on, the Speedlite may not fire or a standard exposure may not be attained.

Set the Master Unit Press the <y> button. The flash ratio control lamp will light. Set the flash ratio. Press <8> or <9> to set the flash ratio within 1:8 to 1:1 or within 1:1 to 8:1. Set the camera and shoot. Set the camera in the same way as with normal flash shooting.
Modeling Flash If the camera has a depth-of-field preview button, press it to fire a 1-sec. burst of flashes. This is the modeling flash. You can check the lighting and shadow effects. Do not fire the modeling flash more than 10 consecutive times. If you fire the modeling flash 10 consecutive times, allow the Speedlite to rest for at least 10 min.
