Optical/Radio AWL
For remote flash lighting that incorporates both optically- and radio-controlled flash units, raise the built-in flash and then attach a WR-R10 wireless remote controller and establish a wireless connection between the WR-R10 and any radio-controlled flash units (0 Establishing a Wireless Connection).
In the photo shooting menu, select Optical/radio AWL for Flash control > Wireless flash options and configure the built-in flash and remote flash units using Flash control > Group flash options. Place optically-controlled units in group A or B.
In Group flash options, press 1 or 3 to place radio-controlled units in group D, E, or F.
The status of radio-controlled flash units can also be viewed by pressing the i button in the flash information display.
