With the AF540FGZ or AF360FGZ, you can discharge the flash to take a
picture at a shutter speed faster than 1/180 second. High-speed flash sync
can be used with the flash attached to the camera, or wireless.
Attaching and Using the AF540FGZ or AF360FGZ on the Camera
1 Remove the cover of the hot shoe and attach the external flash
(AF540FGZ or AF360FGZ).
2 Turn the mode dial and set the exposure mode to b or a.
3 Turn on the camera and the external flash.
4 Set the external flash sync mode to HSb (high-speed flash sync).
5 Confirm that the external flash is fully charged and then take the picture.
By using two external flashes (AF540FGZ or AF360FGZ) or using the
built-in flash with an external flash, you can shoot in P-TTL flash mode
without connecting the flash units with a cord. High-speed sync mode is
also available for wireless shooting.

flash unit.
