Electromagnetic Interferences
Possible electromagnetic interference
This device is protected from electromagnetic interference and electrostatic discharges in a medical
practice. At the same time, the emitted interference is reduced to a minimum. The device thus meets
all requirements of IEC 60601‑1‑2.
The following tests were performed according to IEC 60601-1-2: 2014:
