2 Set the mode dial to b or a.

3 Turn on the camera and the external flash.

4 Set the external flash sync mode to HSb (high-speed sync).

5 Make sure that the external flash is fully charged, and then take a picture.

The b will light in the viewfinder or Live View screen when the flash is ready (fully charged).

High-speed sync is available only when the shutter speed is set faster than 1/180 sec.
