WARNING
ELECTROMAGNETIC INTERFERENCE — Operation of
transmitters outside the designated WMTS frequency band (608-614
MHz) is at increased risk for electromagnetic interference. WMTS is
protected in the U.S. only. This interference could lead to lapses in
patient monitoring and missed alarm events, putting the patient at
risk and compromising patient safety.
WARNING
EMC INTERFERENCE— Magnetic and electrical fields are
capable of interfering with the proper performance of the device. For
this reason make sure that all external devices operated in the
vicinity of the monitoring system comply with the relevant EMC
requirements. X-ray equipment or MRI devices are a possible source
of interference as they may emit higher levels of electromagnetic
radiation.
Interference may cause changes to ECG baseline waveform, which
may not be obvious to a clinician.
