ce. If the button “Return” is not pressed, the display automatically
returns to its normal appearance after approx. 5 seconds.
All flash modes, except remote, are also supported by the second
reflector of the flash unit.
Flash mode with standard foot 301 or SCA adapter from the SCA 300
system
The flash parameters for ISO, aperture and focal length of the lens or reflec-
tor position must be set manually on the control unit of the flash unit (see 7).
The maximum flash range indication in the display of the control unit
depends on the flash parameters set.
Flash mode with SCA adapter from the SCA 3002 system
The flash parameters for ISO, aperture and focal length of the lens or reflec-
tor position are set automatically when the camera transmits the correspon-
ding data to the flash unit (see operating instructions of camera and SCA
adapter).
The maximum flash range indication in the display of the control unit is made
in accord with the flash parameters transmitted by the camera.
If the camera does not transmit one or several flash parameters, these
must be set manually on the control unit (see 7).
6.1 TTL flash mode
The TTL flash mode is only possible if the camera and SCA adapter
support the TTL flash mode (see operating instructions of camera and
SCA adapter)!
In the TTL flash mode a sensor in the camera measures the light reflected by
the subject through the lens (TTL = through the lens). By these means during
the light measurement, for example, filter attachments in front of the lens and
the exact picture segment are taken into account. Where the quantity of light
is sufficient, the automatic exposure system of the camera switches off the
flash light via the SCA adapter.
The maximum flash range can be read on the display. The shortest shooting
distance is approx. 10 % of the maximum flash range. The subject should be

approximately in the centre third of the maximum flash range shown, so that
the automatic exposure system has enough room for equalisation.
For the functioning of the TTL mode the ISO and aperture settings are
irrelevant! If the aperture and ISO values are correctly set, the correct
maximum flash range will be shown in the display.
Setting procedure see cap. 6.
6.2 TTL flash mode with measuring pre-flash
The TTL flash mode with measuring pre-flash is a further development of the
standard TTL flash mode. Here the reflective qualities of the subject are deter-
mined shortly before the actual shot with one or several measuring pre-flas-
hes and evaluated by the camera electronically. In addition, distance data
from the AF system of the camera can be taken into account. The light regu-
lation occurs through the automatic exposure system of the camera via an
adapter from the SCA 3002 system.
The various technologies of the TTL flash mode with measuring pre-flash vary,
depending on the camera system (manufacturer) and camera type.
The various possible flash modes are in addition shown in the menu “Mode”
and can be activated there.
