Manual flash or stroboscopic flash can be set manually with the receiver unit. The setting is independent from the master unit. The mast unit just triggers the receiver unit which fires according to its own independent (manual or stroboscopic flash) settings. This feature can be used in the following situations:

1. As with studio flash units, you can set the receiver units flash output yourself for wireless or manual flash photography

2. For wireless manual flash photography with Wireless Transmitter ST-E2.

	While M is blinking, press the <MODE> button. MULTI will then start blinking
