ۋ If you are using a Canon brand flash unit with ETTL function on your camera, and the EF-500 Super flash unit as
a slave unit, please do not use ETTL function, as the monitor pre-flash may cause the slave to fire prematurely.
Designated Slave Flash
If you use two or more EF-500 Super flash units, you can designate which flashes will fire together by using the
channel settings. In this mode, one flash unit will be used as the Slave Controller and the others for firing as Slaves.

1. Attach the firing flash unit to the camera body.
2. Set the camera’s exposure mode to S or M mode.

synchronized.
