3 f: Set the channel (optical AWL only). Set the remote flash units to the channel selected in Step 2. 4 f: Group the remote flash units. Optical AWL Choose a group (A, B, or C) for each remote flash unit. Although there is no limit on the number of remote flash units that may be used, the practical maximum is three per group. With more than this number, the light emitted by the remote flash units will interfere with performance. Radio AWL Choose a group (A-F) for each of the remote flash units. The master flash can control up to 18 flash units in any combination. 5 C/f: Compose the shot. Compose the shot and arrange the flash units. See the documentation provided with the flash units for more information. After arranging the units, take a test shot to confirm that all flash units are functioning. You can also testfire radio-controlled flash units by pressing the i button in the flash info display (0 222) and selecting M Test flash. 6 C/f: Frame the photograph, focus, and shoot. In radio AWL, the flash-ready indicator will light in the camera viewfinder (0 196) or flash information display when all flash units are ready. The status of radio-controlled units can also be viewed by selecting Flash control > Radio remote flash info in the photo shooting menu. 220
