ge aperture openings. An arrow or triangle after the distance value indicates
that the display range has been exceeded.
6 Displays in the camera viewfinder
Depending on the camera type concerned, different indicators appear in the
camera viewfinder showing the status of the flash unit had been taken. Please
observe therefore the notes in the camera operating instructions!
Examples of indicators in the camera viewfinder:
• The flash symbol flashes prior to the shot being taken:
The capacitor in the flash unit is being charged. The flash unit is not yet flash-
ready
• The flash symbol lights up:
The capacitor in the flash unit is fully charged. The flash unit is ready for use.
7 Flash modes („Mode“)
Depending on the type of camera different TTL flash modes, manual flash mode
and high-speed synchronisation HSS are available. Therefore, data transfer bet-
ween flash unit and camera is necessary before setting the flash mode, e.g. by
actuating the shutter release. The flash mode is set by using the
„Mode“
ባ button.
7.1 TTL-flash modes
The TTL flash modes offer a very simple method of achieving very good flash
shots. In these modes, exposure readings are taken by a sensor built into the
camera, which measures the amount of light through the camera lens
(TTL = „Through The Lens“). Here the camera automatically determines the flash
performance required for a correct exposure of the shot. The advantage of the
TTL flash modes is that all factors influencing exposure (filters, change of apertu-
re and focal length with zoom objectives, extensions for close-ups, etc.) are auto-
matically taken into account in adjusting the flash light.
If the shot was correctly lit, the correct exposure indication ብ will flash „OK“ for
about 3 seconds (see 4.2).
Please note whether there are limitations for your camera in terms of film
sensitivity for TTL flash mode (for example, ISO 64 to ISO 1000; see
camera’s operating instructions)! In analogue cameras there must be a
film in the camera to test the TTL function!
Preflash TTL and ADI metering
Preflash TTL and ADI metering are digital TTL flash operating modes and refined
versions of the TTL flash operation found in analogue cameras. When taking a
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.
Setting procedure
• Press „Mode“ until „
“ flashes in the display.
The setting takes effect immediately. After about 5 seconds the display stops
flashing and the setting is saved automatically. „

There is no setting or indicator for automatic fill-in flash operation on the flash
unit.
TTL flash mode
This analogue flash mode is supported by older analogue cameras. It is the nor-
mal TTL flash mode (TTL flash mode without preflash).
