*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. When using an EX-series Speedlite with fixed flash head and wireless
sensor, take pictures to make sure it can fire.
