Please dispose of the device in accordance with the directive 

2002/96/EC – WEEE (Waste Electrical and Electronic Equipment). If 

you have any queries, please refer to the local authorities responsible 

for waste disposal.

10. Problems and solutions

The machine does not switch on when the ON/OFF button is pressed. 

What should I do? 

(1)  Make sure that the batteries have been inserted correctly and have contact.

(2)  Change the batteries if necessary.

(3)  Contact customer service.

The electrodes are detaching themselves from the body. What should I 

do?

(1)  Clean the adhesive surface of the electrodes with a damp, lint-free cloth. 

Then let them dry in the air and attach them again. Should the electrodes 

still not adhere firmly, they must be replaced.

(2)  Before each application, clean the skin, avoiding using any skin cream or 

oils before treatment. Shaving can increase adhesion of the electrodes.

The machine is giving out abnormal signal tones during treatment. What 

should I do?

(1)  Look at the display. Is any channel flashing?   Interrupt the programme 

by pressing the ON/OFF button. Make sure that the connecting leads 

are properly connected to the electrodes. Make sure that there is a firm 

contact between the electrodes and the treatment area. 

(2)  Make sure that the plug of the connecting lead is firmly connected to the 

machine.

(3)  If the signal tones do not stop and the channel is flashing, change the 

connecting cable. 

(4)  The display shows a flashing battery signal. Renew the batteries.

There is no noticeable stimulation. What should I do?

(1)  If a warning signal sounds, go through the steps described above. 

(2)  Press the ON/OFF key to start the programme again. 

(3)  Check that the electrodes are positioned properly and make sure that the 

adhesive electrodes are not overlapping.

(4)  Increase pulse intensity in stages.

(5)  The batteries are almost empty. Replace these.

You are aware that the electrodes feel uncomfortable. What should I do?

(1)  The electrodes are badly positioned. Check positioning and if necessary 

reposition the electrodes.

(2)  The electrodes are worn. Due to the fact that current distribution can no 

longer be guaranteed evenly over the entire surface, these may lead to 

skin irritation. You must therefore replace these.

The skin in the treatment area becomes red. What should I do?

Stop treatment immediately and wait until the skin has returned to normal. If 

any redness beneath the electrode soon disappears, this is not dangerous 

and is due to the increased circulation which has been stimulated locally. 

If, however, the skin irritation remains and there is possibly itching or inflam-

mation, please consult your doctor before further use. It may possibly be 

caused by an allergy to the adhesive surface.

The belt clip is not secure. What should I do?

If the clip is fastened to the belt and only then connected to the machine, 

there is not optimal hold. You should therefore take the machine in your 

hand. Position the belt clip on the back of the machine. You will notice the 

correct position of the clip when you hear it click into position. Now secure 

the  machine with belt clip on the belt again.
