Additional stimulation duration values (ms key): 0.05 ms / 0.10 ms / 0.30 ms / 0.50ms / 1.00ms
Menu: Setup –> Options –>
Set Extra stimulus duration .
4. Changing the settings during use:
4.1 Change maximum current (mA key): 5 mA / 1 mA possible
4.2 Change stimulus duration for 1Hz/2Hz (ms key): 0.10 ms / 0.30 ms / 1.00 ms for stimulation
(Only framed values can be changed and are immediately active.)
Alternatively: Select the values with the up/down menu keys
–>
Press 5 mA immediately press again 1 mA
5. Plug electrode cable into stimulation needle.
6. Set the stimulation current to the desired value by turning dial.
Red LED blinks; clear warning pitch, warning message: Patient current 0.00
7. Perform puncture with stimulation needle. Warning message disappears. Green LED,
Tone sounds at stimulation frequency.
8. Advance the needle until you observe the desired muscle contractions.
9. When the desired current is reached, turn the dial to reduce the stimulation current until
weak contractions are noticeable.
Use CAUTION in the lower stimulus current range.
10. Inject test dose. Motor responses disappear. Set stimulation current back to maximum.
(no motor responses should be observed) Inject remaining dose.
11. Switch-off: Hold down key for 1 second (the last basic menu settings are reactivated).
Stimulator switches off.

Note:
If the circuit is interrupted or the impedance too high: Red light, warning pitch, warning message appear.
Please check: Is skin electrode dry? - Loose? Stimulation needle plugged in? Cable defective?
