2.2 Adjusting the illuminated field
Duo - Focus system
The illuminated field is adjusted with the sterilisable
handle
and
the keypad on the cardan of the lamp.
There are two possibilities to fit the light field to the
wound area:
-
By
merging the light fields
(see point 2.1.1)
-
By
focusing
(see point 2.1.2) – only available
for DF, DF/H and DF/AF models.
The combination of merging of light fields and focus-
ing
(
Duo-Focus-system
) enables the ideal adjust-
ment of the light field to the wound area in a range
from 8cm to 35cm diameter. Such a large range of
adjustment is not possible with conventional tech-
nique.
All
lamp models (F, DF, DF/H, DF/AF) are equipped
with the feature „
Merging of light fields
“. Turning
the handle
1
activates this feature.
DF-models
also have a “
Focusing
” function (Duo-
Focus). Turn the adjusting ring
2
on the handle or, -
if the lamp is equipped with a keypad at the cardan –
press touch buttons
5, 6
.
Press touch button
5
to expand the focus and touch
button
6
to bundle the light on a minimum area. The
current focused diameter is shown in the LED-
display
4
.
The LED-display
3
serves to merge the light fields
during an operation.
The five triangles represent the distance between
lamp head and wound field. When turning the han-
dle (merging of light fields), the LED-display
3
moves to the left or to the right.
If the LED in the smallest triangle is burning, the
distance is 60cm. The next triangle represents 80cm
and so on.
If the LED in the biggest triangle is burning, the dis-
tance is 140cm.
