ELECTROMAGNETIC COMPATIBILITY
The system is designed to be in compliance with IEC 60601‑1‑2:2007, which contains
electromagnetic compatibility (EMC) requirements for medical electrical equipment.
The limits for emissions and immunity specified in this standard are designed to provide
reasonable protection against harmful interference in a typical medical installation.
The system complies with the applicable essential performance requirements specified
in IEC 60601‑1 and IEC 60601‑2‑18. Results of immunity testing show that the essential
performance of the system is not affected under the test conditions described in the
following tables.
ELECTROMAGNETIC IMMUNITY
