Slave Unit Settings and Position
Regarding your Speedlite (slave unit), refer to its instruction manual and
set it as follows. The settings other than the below for the slave unit's
control are all set with the camera. Different types of Canon Speedlite
slave units can be used and controlled together.
(1) Set the Speedlite as a slave unit.
(2) Set the Speedlite's transmission channel to the same one as
the camera's.
(3) If you want to set the flash ratio (p.196), set the slave unit ID.
(4) Position the camera and slave unit(s) within the range shown
below.
(5) Face the slave unit's wireless sensor toward the camera.
Indoors
Outdoors
*1: If the Speedlite does not have a transmission channel setting function, the
camera can work with any channel.
*2: In small rooms, the slave unit may work even if its wireless sensor does not face
the camera. The camera's wireless signals can bounce off the walls and be
received by the slave unit. With EX-series Speedlite having a fixed flash head
and wireless sensor, make sure it fires, then take the picture.
