Specifics
The following measures can help in case of malfunctions:
Align the IO TTL or the flash new, or newly position it.
Change the distance between the transmitter and the flash/ receiver. If the distance is too short or too long,
it can lead to trigger misfires!
Contact your service, dealer, or distributer.

as classic the flash power. Furthermore, a TTL measurement can be saved and then used continuously.
(see page 10, Operation in TTL Mode).
4. M Mode: The flash power for group A, B and C can be manually controlled with the keys [3].
5. Please note the instructions concerning relative power level in the section “Operation in TTL Mode”.
Synchronization (on the first or second shutter curtain and HSS*)
Please select the FP mode directly on the flash. In order to optimally use HSS, please make sure to work
with fairly long flash duration times.
The selected synchronization setting will be displayed in the “Sync“ section of the LC display [1].
Press the Sync key [6] multiple times to leaf through the different sync options:
Synchronization on the first shutter curtain (1st, also called front curtain). The flash will be
triggered immediately when the first shutter curtain is triggered.
Synchronization on the second shutter curtain: The flash will be triggered directly with the start of
the second shutter curtain.
HSS: High Speed Synchronization (Also known as Auto FP or FP Flash). This allows the
use of shorter shutter speeds than the so-called X-Sync time.
* Please make sure to follow the operating instructions of your camera!
