shot, an almost imperceptible measurement preflash is triggered by the camera
prior to the actual exposure process. The reflected light of the measurement pre-
flash is evaluated by the camera. Depending on the result of the evaluation, the
subsequent flash exposure is adapted by the camera to suit the given shot situa-
tion (see camera operating instructions for further details). In the case of ADI
metering, additional distance data from the lens is incorporated into the flash
exposure process. The selection and/or setting of the preflash TTL and ADI mete-
ring operating modes are carried out on the camera (see camera operating
instructions).
The flash unit must be set to the TTL flash operating mode.

5.3 Automatic fill-in flash mode
With most camera models, the auto programme mode P and subject programme
activate the automatic fill-in flash mode in daylight (see the camera's operating
manual).
With the fill-in flash you can remove annoying shadows and achieve a balanced
exposure between motive and background in shots with backlight. A computer-
controlled metering system takes care of the appropriate combination of shutter
speed, working aperture and flash output.
Ensure that the frontlighting source does not shine directly into the lens, as this
will interfere with the camera's TTL metering system.
Ensure that the contre-jour light source does not shine directly into the
lens, as this will interfere with the camera's TTL metering system.
An adjustment or display for the automatic TTL fill-in flash mode on the flash unit
doesn't occur in this case.

5.4 Automatic flash mode

In the automatic flash mode A, the flash unit sensor
reflects back from the subject. The sensor
only measures the light for the time a flash is fired by the mecablitz. The flash is
cut off as soon as sufficient light has been emitted for correct exposure. The sen-
sor of the mecablitz has to be directed at the subject.
The maximum range is shown on the LC display. The shortest shot distance is
approximately 10% of the maximum distance range. The subject should be loca-
ted within the middle third of the distance range shown on the LC display to
allow the electronic system sufficient leeway for compensation.
Setting procedure:
• Press the „Mode" button until „Mode" flashes on the LC display.
