■ Master unit fires just for controlling the Slave unit, and does not influence photography.
■ When you set a slave unit at the desired position, you can use mini-stand. This mini-stand has a screw
hole for a tripod.
Slave Flash
Normal Slave Flash
Even if the EF-500 DG SUPER SA-N is not attached to the camera body, you can fire the flash by using the
camera’s built-in flash or another flash unit
1. Attach the flash unit to the camera’s hot shoe.
2. Set the camera’s exposure mode to the desired mode. If you use
A or M mode, set the desired aperture
value also.
3. Turn on the flash unit. Then press the shutter button half way.
■ Now, the aperture value and film speed are automatically
transmitted to the flash unit.
4. Remove the flash unit from camera.
5. Press the MODE button and select the
/ (Slave) mode.
6. Press the SEL button several times to make the flash output amount
indicator blink.
7. Press the + button or – button to set the flash output amount.
■ Determine the appropriate flash power by setting the distance indicator on the LCD panel to coincide as
closely as possible, with the actual distance from the slave flash to the subject. If the actual distance is out
of range, you need to change the aperture value.
■ You can set the film speed or aperture value on the flash unit manually, if desired.
a. For the film speed … Press the
MODE
to select the ISO , then press the
SEL
button to make the
indicator blink. Press the + button or – button and set the desired film speed, then press the SEL
button once again.
b. For the aperture value … When the flash unit is set to the Slave mode, press the SEL button to make
the indicator for the aperture value blink, and press the + button or – button to set the desired
aperture value. Then press the SEL button.
8. Press the SEL button several times to make the display stop blinking.
9. Place the slave unit in the desired location. Do not place the slave unit within the Picture area.
10. After you confirm that all flash units are fully charged, press the shutter button to take the picture.
■ When using the EF500 DG SUPER SA-N flash as the "Slave Controller" (on SD9 or SD10 camera) in
Normal Slave mode, please set the flash to "Manual" mode, and adjust the light output to 1/16 power. If
you set it to TTL mode instead, the Pre-Flash system will function, causing the "Slave" (off-camera) flash
unit to fire prematurely.
■ When the EF-500 DG SUPER SA-N is fully charged, the AF Auxiliary Light will blink.
■ 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.
