8. Precautions and Countermeasures of Malfunction Due to Strong
Electromagnetic Wave
The recorder complies with EMC-standard IEC60601-1-2:2007.
However, to prevent electromagnetic interference with other

If the recorder is located near strong electromagnetic waves,
noise may invade in waveforms and malfunctions may occur.
If unexpected malfunction occur during use, check the
electromagnetic interference and take appropriate actions.
