Note!
* During a HSS flash, the flash is pulsing to provide a constant light output during the time when the shutter is
open. To ensure a perfect exposure and a stable flash pulse, the flash uses only the upper part of its power range
when in HSS Mode. Exact range may differ between flash models.
* Frequent use of HSS will have an impact on the life-time of the flash tube.
*Your remote and AirTTL flash may require a firmware update in order to use this feature. The lastest updates and
a list of compatible cameras is available on profoto.com/myprofoto. Create your personal account and login to
access all new upgrades.

Display [2].
1.
Press the Mode button [6] to toggle between TTL and MAN mode.
• TTL mode: The camera dictates the light output of the flashes.
The relationship between the energy levels for group A, B and C
can be adjusted.
• MAN mode: The light output for group A, B and C can be
controlled manually.
Operation in TTL mode (Automatic mode)
In TTL mode the camera dictates the light output of the flashes. If more
than one light is used the relationship between the energy levels for
group A, B and C can be adjusted. This can, for example, be used to
achieve more light on one side of the object.
• Press the A, B or C Group button [4] to select the group you want
to adjust.
• Use the ENERGY buttons [3] to set the relative light output for the
selected group, in relation to the other groups. The relations can
be set ±2.0 f-stop for each group A, B or C. Relations should not be
confused with exposure compensation. Carefully read all the notes
in the end of this section!
• To change the total flash exposure, use the flash exposure
compensation function in the camera. Refer to the camera manual
for details.
• Press the Model button [10] to turn on/off the modeling light in the
selected group.
