MEG010XN102-A11 (ENG)
Description of the anomaly
Possible causes
Actions
Green indicator light off
- power grid problem
- fuses
- check the mains voltage
- check and change fuses
No communication with the PC (home
button = red house)
- USB adapter
- check the connections
- check that the FTDI driver is correctly
installed (CDM21228_Setup.exe )
No stimulation is observed but the yellow
indicators light up.
- bad contact
- defective cable
- check the connections to the patient.
- swap cables for verification
No stimulation and the yellow lights do
not illuminate.
- loss of communication with the module.
- the parameters of the stimulation
currents are not consistent.
- exit the current treatment and return to
the main office.
- check the settings and change them.
Flat trace in biofeedback windows
- loss of communication with the module.
- no sensor on the input in question
- exit the current treatment and return to
the main office.
- check the route used
Need to increase the stimulation current
beyond the usual values with elastomer
electrodes.
- old electrodes
- insufficient frost
- change electrodes.
- add contact gel
Automatic decrease of the amplitude
slider.
- old electrodes
- insufficient frost
- pulse width too long.
- change electrodes.
- add contact gel
- change the programme to a lower
pulse width.
Saturated or very noisy EMG biofeedback
signal
- missing or poor contact of the
reference electrode
- check the correct fixing of the 3
ème
electrode. Check the quality of the
electrodes, replace them if necessary.
If the device is dropped or if water penetrates, it is imperative to have the device checked by
Électronique du Mazet to exclude any risk (patient and user) related to the use of the device.
