2.3 Accessory to Medical Equipment (IEC 60601-1)
In the modern medical environment remote access is essential, for example, to transfer clinical data between doctors and to train to medical students. Both the KW-11T and KW-11R are certified according to the IEC 60601-1-2, Clause 2.1.3, Medical Electrical Equipment, Part 1: General Requirements for EMC standard which is required when accessory devices are used at locations where medical personnel and patients are present.
The KW-11T and KW-11R constitute an optional component that can be considered necessary and suitable as part of medical equipment or for use as part of a medical system to provide real time simultaneous video feeds to those present at the local medical environment and at remote locations. In this environment, the KW-11T and KW-11R can be added to the system ONLY if the connecting equipment has been evaluated and meets the IEC 60601-1-2 EMC standards. Note, that when attaching accessory devices to a digital or analog interface, they must comply with the IEC standard for which they are used: for EMC Standard (IEC 60601-1-2), Information Technology equipment (IEC 60950-1 (2ed)).
