Operating the Device
30 / 62
6. The pump detects when the tube is filled. The device starts the instrument re-
cognition process automatically as soon as pressure conditions have stabilized.
This may take a few seconds..
7. This is followed by three short irrigation cycles.
8. Close the inflow valve. Do not press the START/STOP key. The instrument re-
cognition is lost if the START/STOP key is pressed.
9. Continue with the surgical procedure.
WARNING!
Erroneous measurements
Incompletely opened inflow valve and incompletely closed outflow valve during
the instrument recognition phase can lead to erroneous measurements of the in-
tra-articulate pressure.
Intraoperative instrument change
NOTE!
Instrument recognition
The instrument recognition has to be performed once more if the instrument is
changed during surgery.
How to:
1. Press the START/STOP key to stop the pumping process ("START " operating
mode LED goes out).
2. Change the instrument, open the inflow valve completely, and close the out-
flow valve (drain valve).
3. The instrument recognition should be carried out outside of the joint at a
working height of ± 10 cm. The process takes about 15 seconds.
4. Start the irrigation with the START key. The device will first fill the tube with
fluid.
5. The pump detects when the tube is filled. The device starts the instrument re-
cognition process automatically as soon as pressure conditions have stabilized.
This may take from a few seconds..
6. This is followed by three short irrigation cycles.
7. Close the inflow valve. Do not press the START/STOP key. The instrument re-
cognition is lost if the START/STOP key is pressed.
8. Continue with the surgical procedure.
5.11 Using the WASH Function
To improve visibility within the joint, activate the WASH function. This function in-
creases the pressure by 50 % of the set nominal pressure value for 20 seconds.
However, the maximum pressure of 150 mmHg is not exceeded.
Starting the WASH function
While the device is running, press the WASH key (Fig. Front of the device [ } 22]
(9)
). Tapping the key is confirmed with a low volume acoustic signal (beep).
The WASH LED to visualize the current operating state WASH lights up green.
Stopping the WASH function The pump automatically returns to the previously set operating values after
20 seconds.
To end the WASH function before 20 seconds of WASH time are over, press the
WASH key again. This returns the pump immediately to the previously set operat-
ing value.
5.12 Switching the Device Off
1. Press the Standby/ON key (Fig. Front of the device [ } 22]
(13)
) to turn the
device off.
2. Remove the power connection cable (power cord) from mains socket (Fig. Rear
of the device [
}

(21)
).
