Operating the nerve stimulator 7

Switching on / switching off

Turn the control knob clockwise out of the O position to switch on the Stimuplex® HNS 11. A brief click signals that this has taken place. At this instant, the device automatically starts a self-test. This includes switching on all segments of the LCD display as a visual check. When the self-test is completed, the nerve stimulator immediately switches to its normal operating mode. The LEDs on the button panel indicate the operating conditions selected (see below). To conserve power, these extinguish after 8 seconds. They light up again immediately when a button is pressed, but this does not change the operating mode. The operating mode can only be changed when the displays are lit.

To switch off the nerve stimulator, turn the control knob anticlockwise to position O.
