following points.
WARNING
When the transmitter is used with an electrosurgical unit (ESU), firmly attach the
entire area of the ESU return plate. Otherwise, the current from the ESU flows into
the electrodes of the transmitter, causing electrical burn where the electrodes are
attached. For details, refer to the ESU manual.
NOTE
Noise generated from an electrosurgical unit may interfere on an ECG waveform, but will
not damage it.
