cable in such manner in the device socket, so that the red markings on the device socket and on the
connector shell are aligned.

The plug can be plugged in only in this position; it may not be inserted in any case by using force.
Now insert the plug all the way. When the plug has been inserted, it is locked in position and can
not be inadvertently disconnected by pulling at the electrode cable. To disconnect the electrode
plug, take hold of it at the structured surface near the red dot using your thumb and index fi nger.
The locking mechanism of the plug will be disengaged automatically by pulling away from the
device, and the plug can then be removed without problems. The electrode cable cannot be
removed otherwise, or the device or the electrode cable may be damaged. The LCD display shows
the adjusted nominal stimulation current. The available adjustment range (peak value) may vary (6.0
mA or 20.0 mA), depending on the selected mode.

Performance of the short-circuit test:
Connect the socket of the stimu-
lating electrode to the stimulating electrode clamp with the aid of the
supplied red test-plug (
⫽
short circuit). Then increase the nominal stimu-
lating current by turning the knob clockwise to at least 1.0 mA and check
the »

«-symbol on the display. The display must exhibit an »

moments later.

If the display should permanently show a dissimilar function (»

« symbol),
there must be a fault in the patient stimulation circuit.
4. Disconnect the electrical connection between the electrode plug and the electrode clamp and
remove the red test-plug. A »
⬆
« symbol may now be seen on the LCD. This indicates, that the
selected nominal stimulating current is dissimilar to the actual stimulating current. If the behavior
is different from the one described in 3 and 4, then a faulty cable could be the cause (short-circuit/
interruption). Check the function once more with a second cable. Finally, remove the red short-cir-
cuit plug from the socket of the electrode.
5. Switch the MultiStim off by pressing the ON/OFF/PAUSE button for a longer period of time (min. 2
seconds). (Please observe section Switching ON and OFF) You should turn the device off after use
to spare the battery. If you don‘t use the device for a longer period of time, you should remove the
battery to avoid leakage.
6. Please observe the Warnings and precautionary measures before you use the device on a patient.
The stimulation mode stored last will remain stored after turning the device off. When the device is
switched on again, this setting is reloaded and the stimulation current is set to 0.00 mA, or to a value
you have previously selected. The stimulation pulse width is set to the following default-values after the
device is switched on:
Mode:
KAN
cannula 0 – 6 mA
CATH catheter 0,0 – 20mA
Before every application on a patient, the device settings have to be checked and altered if necessary.
4.2 Operation of the nerve stimulator
Switching ON and OFF
Pressing the ON/OFF/PAUSE-button will switch the MultiStim SWITCH on.
After switching on, the device will fi rst perform an automatic self-test. Upon the successful
completion of the self-test, the device will immediately change to the PAUSE-mode. For the protection
of the battery, the device will automatically switch itself off with a previous acoustic warning after 20
minutes have elapsed since the last pressing of a button. The device is switched off by pressing the
ON/OFF/PAUSE button for at least two seconds while the device is turned on.
