The Y icon flashes when the masterflash is in mode M.D Commander ModePosition the sensor windows on the remote flash units to pick up thelight from the master flash (particular care is required if the camera isnot mounted on a tripod). The remote flash units should normally beplaced closer to the subject than to the camera. Be sure that directlight or strong reflections from the remote flash units do not enter thecamera lens (in TTL mode) or the photocells on the remote flash units(AA mode), as this may interfere with exposure. To prevent timingflashes emitted by the master flash from appearing in photographstaken at short range, choose low ISO sensitivities or small apertures(high f-numbers) or rotate the flash head on the master flash to pointupwards. After positioning the remote flash units, take a test shot andview the results in the camera monitor.Although there is no limit on the number of remote flash units thatmay be used, the practical maximum is three.
