15-2 EMC Guidance and Manufacturer’s Declaration
The system needs special precautions regarding EMC and needs to be installed
and put into service according to the EMC information provided below.
2 Other devices may interfere with this system even though they meet the
requirements of CISPR.
3 Preventing conducted RF immunity. Due to technological limitations, the
conducted RF immunity level are limited to 3Vrms level, conducted RF
interference above 3Vrms may cause wrong diagnosis and measurements. We
suggest that you position system further from sources of conducted RF noise.
Portable and mobile RF communications equipment can affects system. See
tables 1, 2, 3, and 4 below.
If the system is operated within the electromagnetic environment listed in Table 2 and Table 3,
the system will remain safe and will provide the following basic performances:
Imaging;
Doppler acoustic spectral displaying;
Taking measurements;
Patient information;
Date/time information.
TABLE 1
GUIDANCE AND MINDRAY DECLARATION—ELECTROMAGNETIC EMISSIONS

RF emissions
CISPR 11
Group 1
The system uses RF energy only for its
internal function. Therefore, its RF
emissions are very low and are not likely
to cause any interference in nearby
electronic equipment.
CISPR 11
Class B
The system is suitable for use in all
establishments including domestic
establishments and those directly
connected to the public low-voltage
power supply network that supplies
buildings used for domestic purposes
