a: Fully Automatic Wireless Flash Shooting
Advanced Shooting with Fully Automatic Wireless Flash
Flash exposure compensation and other settings set on the sender unit
will be set automatically on the receiver unit(s). You do not need to
operate the receiver unit(s). Wireless flash shooting with the following
settings can be performed in the same way as in normal flash shooting.
• Flash exposure compensation
(f/p.24)
• FE lock (p.25)
You can also directly operate the receiver unit to separately set flash

exposure compensation and flash coverage on each receiver unit.
You can also perform FEB shooting and stroboscopic flash using the

430EX III-RT set as a receiver unit with a sender unit equipped with FEB
and stroboscopic flash functions.
Sender Units
You can use two or more sender units (sender units + receiver units =
maximum of 16 units). By preparing multiple cameras with sender units
attached, you can perform wireless flash shooting by changing cameras
while keeping the same lighting (receiver units).
Note that when using two or more sender units, the color of the <D>
lamp varies depending on the order in which the power was turned on.
The first sender (main sender) is green, and the second and
subsequent senders (sub-senders) are orange.
If the <D> lamp is red, the connection has not been established. After
checking the transmission channel and wireless radio ID, turn each sender
unit off and on again.
You can take pictures regardless of the main sender and sub sender status.
