4 Testing and setting the intensity
You can check the intensity of the electrical stimulation before use
and specify at which intensity the EMS electrodes should provide
stimulation upon detecting that you are on your back. The device
has a total of 20 intensity levels. Use the +/− buttons to set your de-
sired intensity. Press the + button to increase the intensity, and the
− button to reduce the intensity. Never set the intensity to a level at
which electrical stimulation feels uncomfortable for you.
1 LED lights up = Intensity level 1 to 5
2 LEDs light up = Intensity level 6 to 10
3 LEDs light up = Intensity level 11 to 15
4 LEDs light up = Intensity level 16 to 20
5 Activating the function to detect when you are lying on
your back
Once you are happy with the intensity of the electrical stimulation,
you can confirm your selection by briefly pressing the ON/OFF
button . This switches off the LEDs so as not to disturb the users
while they are sleeping. The detection function for when you are
lying on your back will now begin. As soon as it has been detected
that you are lying on your back, electrical impulses will be trans-
mitted to your body through which you will be prompted to change
your sleeping position.
6 Switching off the control unit and removing the anti snore belt
To switch the control unit off again, press and hold the ON/OFF but-
ton until the control unit vibrates and the LEDs go out. Undo the
anti snore belt.
To charge the control unit, pull the control unit off the anti snore belt.
Clean the anti snore belt as described in chapter "9. Cleaning and
maintenance".
