Instructions
Slide your Canon flash into the included mini-flash stand. The flash's hot shoe connector will fit into the track at the top of the mini-flash stand.
Line up the threaded hole at the bottom of the mini-flash stand with the fastening screw at the top of your light stand. Turn the fastening screw clockwise until the flash unit is snug.
Turn on your flash and flip the bottom switch to the rightmost "Slave" position. This will activate the flash's remote triggering capabilities.
Attach a master flash (a standard flash unit in the "Master" position) or a remote radio trigger to your camera's hot shoe.
Use your camera normally. You will automatically trigger the slave flash to fire either with infrared light from your master flash or with a radio transmission from your remote trigger.
