Strong electromagnetic interferences that occur in the close vicinity of electrical motors, power cables,
PCs, monitors or other – possibly defective – electrical devices may compromise the function of the
device in certain cases.
This kind of device malfunction should be considered as a possible cause if the following is observed:
•
The device switches on by itself.
•
The device displays other inexplicable behaviors.
Correct operation of the device can be restored by the following methods:
•
Switch off the interfering electrical device.
•
Remove the source of interference from this device.
•
Switch this device off and on.
If the interference continues, contact BIOTRONIK immediately.
WARNING
Risk of electromagnetic interference through the use of unauthorized accessories
The use of accessories, transducers, or cables not listed by BIOTRONIK or of accessories other
than those specified by BIOTRONIK, can produce elevated electromagnetic emissions or cause
degradation in the device's resistance to electromagnetic interference. Such effects can lead to the
faulty operation of the device.
•
Only use accessories authorized by BIOTRONIK.
