Canon SPEEDLITE 430EX Mode D'emploi page 25

Wireless Flash
With multiple Canon Speedlites having the wireless flash feature, you can
create various lighting effects with the same ease as using normal E-TTL II
autoflash.
The settings you input with the master unit attached to the camera are also
transmitted to the slave unit(s) controlled by wireless. Therefore, you need
not operate the slave unit(s) at all during the shoot.
For details on wireless flash photography and operating the master unit,
see the master unit's instruction manual. The procedure below applies to a
master unit attached to the camera and slave unit(s) controlled by wireless.
