Appendix 1. Electromagnetic compatibility
Like other electrical medical equipment, the system requires special precautions to ensure
electromagnetic compatibility with other electrical medical devices. To ensure electromagnetic
compatibility (EMC) the system must be installed and operated according to the EMC
information provided in this Instructions for Use. The system has been designed and tested to
comply with IEC 60601-1-2 requirements for EMC with other devices.
Guidance and manufacturer's declaration – Electromagnetic emission
The system is intended for use in the electromagnetic environment specified below.
The customer or the user of the system should assure that it is used in such an environment.

Note 1: The emissions Characteristics of this equipment makes it suitable for use in industrial areas and
hospitals (CISPR 11 class A). If it is used in a residential environment (for which CISPR 11 class B is normally
required) this equipment might not offer adequate protection to the radio-frequency communication service.
The user might need to take mitigation measures, such as relocating or re-orienting the equipment.
Guidance and manufacturer's declaration – Electromagnetic immunity
The system is intended for use in the electromagnetic environment specified below.
The customer or the user of the system should assure that it is used in such an environment.

Electromagnetic environment guidance
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.
The system is suitable for use in all
establishments other than domestic, and may be
used in domestic establishments and those
directly connected to the public low-voltage
power supply network that supplies buildings
used for domestic purposes, provided the
following NOTE 1 is heeded.
