Owner's Manual

Using a Canon Speedlite (master/slave) equipped with the radio
transmission wireless shooting function, you can easily perform
wirelessly-controlled shooting with multiple flashes in the same way as
normal E-TTL II/E-TTL autoflash shooting.
The system is designed so that the settings of the 430EX III-RT
(master) attached to the camera are automatically applied to the
wirelessly controlled 430EX III-RT (slave). Therefore, you do not need
to operate the slave unit while shooting.

You can also wirelessly control a 430EX III-RT set as the slave unit with
a device that is equipped with the radio transmission wireless master
function other than a 430EX III-RT. For details on setting the master unit
functions, refer to the instruction manual of the device.
Position the slave unit, using the provided mini stand (p.14).
