In the 
operating mode, the LCD display shows the preselected stimulation current set on the controller between 0.00 and approx. 1.00 mA (in the 1 mA range) or from 0.00 to approx.
5.00 (in the 5 mA range). In the 
operating mode, the Stimu- plex® HNS 11 shows the stimulation current actually flowing via the stimulation electrodes through the tissue. A ”+” sign on the LCD display signals this setting. The operating mode is switched by pressing the ”mA” button.
3.Select operating mode
. Set the controller to 5 mA max. and try to get a connection with the insulated, black 2 mm male plug
with a part of the red clamp. Compare – by briefly switching to
operating mode
– the measured value with the set value (ac- tual value and set value). These two values must be the same – with shorted cables. Reset to 1 mA max. and compare these two values (see Measuring Accuracy in Appendix A, if neccessary).
A ~ symbol appears next to the ▲ symbol in the LCD display (Display) and the pulsed LED display (orange
A "+" sign appears in front of each measurement displayed.
When a current is set at O, the orange LED starts to blink at 0.02 mA, when 1 mA max. is set, and at 0.10 mA when 5 mA max. is set.
4.When the stimulation cable is disconnected (when
is set), +0.00 appears in the display and the ~ symbol disappears. The pulsed LED display is no longer lit.
If the "BAT" symbol appears in the display, then the battery voltage is getting too low. Current application can be complet- ed without a problem, but exchanging the battery afterwards should be considered. Press the "BAT" button to display the re- maining battery voltage (in volts).
When the battery voltage is approx. 6 volts, three horizontal dashes preceded by the "+" sign (or four dashes) appear in the display in addition to the "BAT" symbol. In this case, the stimu- lator shuts off automatically.
To avoid having to abort a stimulator treatment, you should replace the 9 volt block battery as soon as the battery volt- age drops to 6.5 volts.
5.To switch off the nerve stimulator, turn the control knob anti- clockwise to position O.
To conserve the battery always switch off the Stimuplex® HNS 11 after use. If you do not use it for a long period of time, remove the battery to prevent battery leakage.
