10. Troubleshooting
Problem/question Possible cause/remedy
The unit does not switch on when
you press the ON/OFF button.
1. Ensure that the batteries are inserted correctly and have contact. The
on/o button must be pressed and held down to switch the unit on.
2. If necessary, replace the batteries.
3. Please contact customer service.
No stimulation can be felt. 1. Increase the pulse intensity incrementally.
2. Press the on/o button to restart the program.
3. The batteries are almost empty. Replace them.
You feel an unpleasant sensation
from the electrodes.
The electrodes are poorly moistened. This can lead to skin irritation, as
the current is no longer distributed evenly over the entire surface. Switch
o the unit. Take o the belt, moisten the belt (electrodes) and your lower
back and restart the program according to the manual.
The skin in the treatment area
becomes red.
Discontinue the treatment immediately and wait until the skin returns to
normal. Temporary skin reddening under the electrode is harmless and
is a result of increased blood flow. However, if the skin irritation persists
and you feel itching or irritation, consult your doctor before continuing
use.
