Safety and Electromagnetic Compatibility
Electromagnetic compatibility (EMC) is provided by IEC 60601-1-2:2007 requirements
fulfillment.
The screening systems are intended for operation in the electromagnetic environment
conditions which are specified in the appendix 1 “Electromagnetic Emission and
Immunity”.
Portable and mobile RF communication equipment may affect the system work.
The use of the equipment not listed in table 2 and table 3 of the present technical
manual may result in increased emission and system decreased immunity.
As for safety, screening systems satisfy IEC 60601-1:1988 + A1:1991 + A2:1995, IEC
60601-1-1:2000, IEC 60601-2-40:1998 standards requirements. The devices are
supplied by the external power supply unit of 9 V direct voltage or Li-ion rechargeable
battery, are related to class I and have BF type work parts according to IEC 60601-1.
All the computer equipment used together with the devices should correspond to IEC
60950-1 and CISPR 22:2006.
Interpretation of symbols on the electronic unit:
- attention: consult user and technical manuals.
- work parts of BF type according to IEC 60601-1.
