Remote Release from Slave Unit
When performing wireless shooting, E3
+
transmitter supports remote release (remote
control shooting) from a flash set or E3
+
receiver as a slave unit. For operations, see
the flash or E3
+

Note
When using the remote release function, the slave unit camera might need a shutter
release cable(available separately) depending on the camera models.
1) EOS digital cameras since 2012 do not need to use shutter release cable.
2) EOS cameras before 2012, which are compatible with E-TTL II/E-TTL autoflash
and come with N3 type remote terminal EOS, shutter release cable will be needed
for linked shooting.

You can fire a test flash from a flash set as a slave unit. For operations, see the flashs
instruction manual.
Note: When two or more units are set to master, the unit with the <LINK> lamp lit in
green is the one that fires.
