and then regularly (e.g. before daily use):
--
Visual inspection of device and accessories
--

2.2 Functional check of Stimuplex® HNS 12
Switch on the nerve stimulator. Target stimulation current = 0.00 mA, LED is not flashing, and no
sound is audible. Battery symbol may not be flashing (battery voltage > 7 V).
