Radio Transmission
This chapter describes wireless flash shooting.
For the accessories required for wireless shooting,
see the system map (p.60). For the regions of use,
restrictions, and precautions related to radio
transmission, refer to the separate leaflet.
When the camera’s shooting mode is set to a fully automatic
mode or an Image Zone mode, the operations in this chapter
are not available. Set the camera’s shooting mode to V/X/
W/q/5 (Creative Zone mode).
The transmitter attached to the camera is called the master unit,
and a flash that is wirelessly controlled is called the slave unit.
