8. RELEASE
Siros L monolights are supplied with the RFS 2 module built in.
8.1 RFS 2 module (radio frequency system)
For RFS 2.1 / RFS 2.2 flash control, the channel (studio address) must correspond to the trans-
mitter's channel. The studio address is set in the menu at position “st”. The lamp channel is defined
in the menu under “lamp”. See Section 10.3 for more information about changing the colours of the
cognition lights.
With the radio transceiver, you can define and set the individual lamps as you wish. To learn how to
do this, please see the operating instructions for the transceiver. The transceiver is not included in
the scope of supply as standard.
8.2 Photocell (cell)
The photocell can be switched on and off using the menu function “sync” (11). When it is active, the
blue LED beside the “cell” label is illuminated. After the first flash of a sequence, the active photocell
is deactivated, and the blue LED beside the “sync” button (11) blinks. Pressing the “test” button
switches it on again.
8.3 Synchro socket (12)
The sync cables, 5 m (16.4 ft) (Art. No. 34.111.00) or 10 m (32.8 ft) (34.112.00), can be fitted to the
socket for cable release (12).
8.4 “test“ button (4)
Using this button, the monolight can be triggered manually. The flash can be triggered as soon as
90 % of the set energy level is reached. The visual “ready” indicator, on the other hand, only illu-
minates when 100 % is attained.
9. HS FUNCTION
In combination with the RFS 2.2 transmitter, you can use all Siros L monolights with extremely fast
shutter speeds. For example, with ambient light, even with the aperture wide open (selective focus),
the image can be underexposed correctly with up to 1/8000 s and Siros L still lets you set dominant
and creative light effects.
All you need for this is the RFS 2.2 transmitter, which is available for Canon, Nikon and Sony
cameras. In addition, HS must be activated on all Siros L units. This modifies the flash curve and
guarantees, in combination with RFS 2.2, correct exposure with no limits on your choice of shutter
speed.
Please read the operating instructions for the RFS 2.2 transmitter to learn more about optimum
use of the HS function.
While working in HS mode you are only able to use flash power level 4 to 10 with Siros L.
