10.1 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.
Portable HF communications equipment (including peripherals such as antenna cables
and external antennas) should be used no closer than 30 cm to any part of the device,
including cables specified by the manufacturer. Otherwise, performance may be
impaired.
The use of this device next to or with other devices should be avoided, as this can result
in incorrect operation. If such use is necessary, this and the other devices should be
observed to ensure that they are operating correctly.
WARNING
Reduced immunity! Risk of injury!
The use of accessories or cables other than those specified in the KARL STORZ instructions
for use may result in increased emissions or decreased immunity of the product. The cables
listed have been shown to comply with the requirements of IEC 60601-1-2.
When using other cables, the operator is responsible for checking that they comply with
IEC 60601-1-2:2014.
