test flash, then the next lower f- number must be set to widen the
aperture, or the distance to the reflection surface or subject has to be
shortened. Thereafter repeat the test flash.
The f-stop established in this manner also has to be set on the
camera.
Direct the flash unit with its sensor for the test flash in the same man-
ner as for the subsequent flash shot.
An audible warning signal
(fig. 5). When the shot has been correctly exposed there will be a
continuous audible buzzing signal

2.6 Possible types of buzzer signals

A continuous audible sound is generated after a flash has been fired
and both the exposure o.k. indicator
cator light up - correct exposure and flash readiness.
A continuous audible sound is generated after a flash has been fired
and only the exposure o.k. indicator
exposure, but no flash readiness.
There is no audible sound after a flash has been fired, and the expo-
sure o.k. indicator (fig. 3) and flash ready indicator
up - underexposure.

3. TTL Flash Mode

(only with SCA adapter)
Perfect flash exposures can be shot in a simple manner in TTL mode.
The exposure readings in TTL mode are made by the sensor built into the
camera (fig. 5). This sensor measures the light reaching the film through the
camera lens. As soon as the film has been exposed by the correct amount of
light, an electronic control circuit within the camera transmits a stop signal to
the adapter (optional accessory), and the flash is instantly cut out.
The advantage of this flash mode is that all factors influencing the exposure
of the film (filters, change of aperture and focal length with zoom lenses,
can be turned on with the switch ²
for approx. 1 second.
(fig. 3) and flash ready indi-
(fig. 3) lights up - correct
do not light
extensions for close-ups, etc.) are automatically taken into account.
The TTL flash mode is only possible with cameras that feature this func-
tion. The flashgun must be fitted with a corresponding SCA adapter for
this purpose. A film must be loaded in the camera to test the TTL func-
tions.
Exposure corrections may be necessary with pronounced differences in
contrast, for instance dark objects in snow (see Ch. 10.2).
Adjusting procedure for TTL flash mode:
• Set the camera as indicated in the camera's operating instructions.
• Equip the flash unit with the appropriate SCA adapter and mount on the
camera.
• Turn on the flash unit with the main switch ¸ (fig 6).
• Push the locking key (fig. 3) downwards and unlock the setting centre.
• Turn the knurled knob (fig. 3) until "TTL" appears in the window
3).
• Push the locking key upwards and lock the setting centre.
The maximum flash range for the given camera aperture can be read off the
setting dial on the reflector opposite the camera's f-number.
Set the index mark · (fig. 4) in the "Man.:1" position. The minimum flash-
to-subject distance amounts to approx. 20% of the maximum flash range.
To check the range, the flash can only be fired by the camera and not
by way of the manual firing button on the flashgun (where possible
the camera should be adjustet to multiple exposure.
