Test Flash and Modeling Flash from a Slave Unit

In radio transmission wireless shooting, you can fire the test flash and
modeling flash (p.47) from a 600EX II-RT set as a slave unit.
Modeling flash is not possible from a slave unit with cameras released up
to 2011 or with EOS REBEL T6/1300D or EOS REBEL T5/1200D.
For the precautions related to modeling flash, see page 47.

be fired even if you select <M>.
When there are two or more master units (p.72), the flash signal is sent to
the main master that has the <D> lamp lit in green.
