unit to ascertain whether it works with or without preflash. If the
flash unit does not fire, change to
• In most cases, several test shots with different positions of the
flash unit, alignments of the reflector head and settings of the
devices are needed to achieve the desired illumination.
However, in very bright ambient light is may nevertheless be
impossible to achieve appropriate flash illumination.
• The AF preflash function on the camera must be switched off.
• The zoom reflector is automatically set to 24 mm, but you can
also select one of the other focal lengths (see p. 36).
• If several flash units of this type are to be used remotely from
the camera, they must all be set to the same mode.
Important:
Do not mount the flash unit on metal accessory shoes that may
cause a short circuit and thus damage it.

SYNCHRONIZATION
The flash synchronization speed (fastest possible shutter speed for
flash shots) is automatically set for the camera's exposure modes,
i.e. programmed automatic (P), shutter priority (S/T), aperture
priority (A) and manual setting (M). With S/T and M you can also
use slower shutter speeds.
Furthermore, in the A , TTL and
operation with faster shutter speeds is also possible with cameras
with the appropriate specifications (
Other flash-related functions possibly set on the camera, such as
slow speed synchronization, synchronization to the end of the
exposure and preflashes against the red-eye effect, are also
possible.
Please refer to the instructions of the camera used for details on
these camera functions.
