By using two external flashes (AF540FGZ or AF360FGZ) or using the
built-in flash with one or more external flashes, you can shoot in P-TTL
flash mode without connecting the flash units with a cord.
First, set the channel for the external flash unit.

2 Remove the cover of the hot shoe and attach the external
flash.
3 Turn on the camera and the external flash, and press the
shutter release button halfway.
The built-in flash is set to the same channel as the external flash unit.
Using Flash in Wireless Mode
• Set the power switch of the external flash to WIRELESS.

high-speed flash sync in wireless mode. This function cannot be used in
combination with the built-in flash.

camera to SLAVE.
Setting the Channel for the External Flash
• When set to r mode, the channel currently set for the built-in flash is
displayed in the viewfinder for 10 seconds.

AF540FGZ or AF360FGZ for details on how to set the channel on the
external flash.
