b) digital secretion aspirators M20D and M30D
The digital network-independent versions
operate vacuum-controlled. The vacuum is
set via the keyboard foil on the front side of
the devices, where the tolerance for the ac-
curacy of the vacuum display is 10 %. This
technology enables efficient and economical
operation with the energy resources during
battery operation.
1. Switch on the device by pressing the ON/
OFF button (fig. 3(E)). The ON LED signaliz-
es that the pump is switched on by illumi-
nating green.
Immediately after switching on, one
of the 8 vacuum display LEDs (fig. 3
(G)) illuminates red for 2 seconds to
show the vacuum value that was last
set or that was present during start-up
(target value display).
2. Set your desired vacuum via the ar-
row keys (fig. 26(1)). When the device
is later switched off, the last set value is
saved.
3. The display via the red LED signalizes the
selected target value of the vacuum to you.
The automatic switch over to the current
vacuum via a green LED occurs after 2 sec-
onds.
4. You can also perform fine adjustments to
the set vacuum via the additional air open-
ing on the fingertip.
For immediate maximum vacuum:
• If you require the maximum value quickly,
press the ‘max’ button (fig. 28(2)). You can
also set the maximum vacuum by pressing
the ‘up’ button several times.
• Preselection of the maximum vacuum is
signalized via a red LED for 2 seconds (fig.
28(3)).
3.4.3 Aspiration
1. Perform the aspiration procedure as you
were instructed by specialized personnel.
2. Control the aspiration procedure and the
desired vacuum using the additional air
opening on the fingertip (fig. 27).
3. Shut down the device after the aspiration
procedure according to section 3.6.
