unit to fire prematurely.

■ The flash will not fire if the EF-500 DG SUPER SA-N is attached to the camera body while it is in the Slave
Mode setting.
Designated Slave Flash
If you use two or more EF-500 DG SUPER SA-N 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.
Setting the Slave Flash unit(s) for firing
1. Attach the firing flash unit to the camera body.
2. Set the camera's exposure mode to S or M mode.
■ Then set the shutter speed to 1/30 or slower. The slave Controller
will transmit the designated signal before the others fire. Thus if you
use a shutter speed faster than 1/30, the firing flash units will not be
synchronized.
