5. Initial operation
Switch on the lights (1) by pressing shortly the respective
control dial (15) (fig. G). Now you can adjust the brightness
of each light individually with the correspondent control
dial (15). The display (16) shows the brightness setting in
1 %-steps from 10 % up to 100 %.
If you want to adjust the brightness of both lights syn-
chronously, connect the lights with the light synchro cable
(17). Insert the plugs (19) into the respective port (20) (fig.
H); they click into place audibly. Now any of the control di-
als (15) can be used to adjust the brightness of both lights
combined.
If you want to control the brightness of the lights separately
again, disconnect the lights by unplugging one or both
plugs (19) from the port(s) (20). Push the latch release (18)
towards the plug (19) to unlock the plug. Do not apply force
when releasing the plug to prevent damage of the port or
plug.
Switch off each light separately when not in use by press-
ing the respective control dial (15) shortly.
6. Adjustments
The lighting unit can be adjusted in a variety of ways (see
fig. I – L). To adjust it, release the respective fastening
screw (22), (12) or (7) and tighten it again.
7. Removing / Inserting soft screen
The lights are equipped with a
soft screen
(4) for particular
soft light. If this is not required and if there is a need for
more light, the lights can also be operated without the soft
screens. To remove the soft screen camber it at the narrow
side a bit outwards and remove it – starting from the cam-
bered narrow side – from the guide slot of a long side
(fig. M).
To reinsert a soft screen, place it in the guide slot of one
long side, then camber it on one narrow side a bit outwards
and push it – starting from the cambered narrow side – into
the guide slot of the opposite long side. It is irrelevant which
side of the soft screen faces outwards.
A
polarizing foil
(optional accessory) can also inserted or
removed in the same way. The polarizing foil can be used
with or without the soft screen. When used with the soft
screen the polarizing foil must be placed at the outside.
8. Maintenance and care
The lights are maintenance-free. Make sure that the soft
screens (4) are free of stains and dirt. If necessary remove
these before operation.
Clean the devices with a soft dry cloth. On no account use
petrol or other solvents.
