8.1 General notes on the operating environment

The product is suitable for use in professional healthcare settings. Professional healthcare
facilities include physician offices, dental offices, limited care facilities, freestanding surgical
centers, freestanding birth centers, multiple treatment facilities, hospitals (emergency rooms,
patient rooms, intensive care, surgical rooms, outside the HF-shielded room of an ME system
for MRT).
The emission characteristics of this product make it suitable for use in professional
healthcare facilities as well as in a residential environment (CISPR 11 Class B). This
product offers adequate protection to radio communication service. In the rare event of
interference to the radio transmission operation, the user might need to take mitigation
measures, such as relocating or re-orienting the product.
