Measures to be taken
Note 1: The floor should be in antistatic material (wood, ceramic, ect.). If covered by synthetic
material, relative humidity should be maintained at least at 30%.
Note 2: The quality of the electrical power supply and the mains frequency magnetic fields
should be typical of domestic, commercial and hospital environments.
Note 3: If the operator has to work without a break while power supply is interrupted, it is
necessary to have power supplied through a UPS (Uninterruptible Power Supply) unit.
1.10.1 RECOMMENDED DISTANCES FROM RADIOFREQUENCY (RF)
COMMUNICATION SYSTEMS
As stated in the chapter 1 “Information about safety” of this operator manual, it is
recommended to not use Radiofrequency (RF) transmission system near the
medical device. RF systems can cause interference which may cause instability
and interferences with the correct working of the equipment and it may alters the
signal acquired tracing.
The operator can prevent interference caused by electromagnetic field by
maintaining a minimum distance between the medical device and the RF
communication system being used (cell phones, mobile phones, etc,).
The following table shows the minimum distances in meters, according to the
maximum power at RF system output.
