pre-flash (e.g.. Canon E-TTL, Minolta ADI, Nikon D-TTL, Nikon iTTL etc).
The standard TTL flash mode is not supported by these cameras. For
more details, see operating instructions of camera and SCA adapter.
Setting procedure see cap. 6.
6.3 Automatic flash mode
In the auto flash mode A, a sensor in the control unit of the flash unit mea-
sures the light reflected off the subject. The sensor has a range of approx.
25°, and only measures during its own light emission. If the amount of light is
sufficient, the automatic exposure system of the flash unit switches the flash
off. The sensor must be directed towards the subject.
The maximum flash range is shown 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.
Some cameras will not support the auto flash mode A when the flash
unit is equipped with an adapter from the SCA 3002 system. In this
event the use the standard foot 301.
Setting procedure see cap. 6.
6.4 Manual flash mode M
In the manual flash mode M, the flash unit will emit the full light energy if
partial light output has not been set. Adaptation to the given photographic
situation can e.g. be achieved by setting the corresponding aperture on the
camera or by selecting a suitable partial light output level
The display indicates the flash-to-subject distance for correct flash exposure.
Some cameras will not support the manual mode M when the flash
unit is equipped with an adapter from the SCA 3002 system. In this
event the use the standard foot 301.
Setting procedure see cap. 6.
6.5 Stroboscopic mode
The stroboscopic flash mode is a manual flash mode. When using it several

flash exposures can be used on one shot. This is particularly interesting for
motion studies and special effects (Fig. 7). In stroboscopic mode, a predeter-
mined number of flashes are fired at a certain flash frequency. Consequently,
only a partial light output is available with a maximum of ? power.
For stroboscopic exposures, you can select a flash frequency (flashes per
second) of 1…50 Hz in 1 Hz increments, and a number of flashes between
2 … 50 in single increments (see 7).
The maximum possible partial light output level in stroboscopic mode is auto-
matically adjusted. It depends on the ISO and aperture values. To achieve
short flash durations, the partial light output level can be adjusted manually
to a minimal value of 1/256.
The display indicates the correct distance for the parameters set. You can
adjust the distance displayed to the distance to the subject by varying the
aperture value or the partial light output.
No aperture and ISO values are shown in the display in stroboscopic
mode! The stroboscopic mode cannot be used when the secondary
reflector is switched on.
Setting procedure see cap. 6.
7. Flash parameters (Parameters menu)In order for the flash unit to function properly, it is necessary that you adjust
various parameters, such as the zoom position of the flash reflector, aperture,
light sensitivity ISO etc, to the settings of the camera.
The flash parameters must be set manually when the flash is operated with
the standard foot 301 or an SCA adapter from the SCA 300 system.
When operating the flash unit with an SCA adapter from the SCA 3002
system the flash parameters are set automatically if the camera sends the cor-
responding data to the flash unit (see operating instructions of camera and
SCA adapter). For the purposes of the automatic data transmission, the com-
bination of camera, flash unit and SCA adapter must be mounted and swit-
ched on. In addition, an exchange of data must occur between camera and
flash unit. It is enough simply to tap the camera release lightly.
