HF emissions CISPR 11 Class A The properties of this device in terms of its emissions
mean it can only be used in medical facilities that are
connected to supply systems specifically provided for
that purpose (usually supplied via isolating transform
-
ers). For domestic use (for which class B is usually
required as per CISPR
11), this device may not offer
adequate protection against radio services. The user
may need to take corrective measures such as relocat
-
ing or reorienting the device.
