Electromagnetic Emissions and Immunity
The EMC standards state that manufacturers of patient-coupled equipment must specify immunity
levels for their systems. See Tables 1 to 4 for this detailed immunity information. See Table 5 for
recommended minimum separation distances between portable and mobile communications
equipment and the product.
Immunity is defined in the standard as the ability of a system to perform without degradation in the
presence of an electromagnetic disturbance.
Caution should be exercised in comparing immunity levels between different devices. The criteria used
for degradation are not always specified by the standard and can therefore vary with the manufacturer.
In the table below, the term "device" refers to the Avalon FM20/30/40/50 fetal monitor together with
its accessories. The table gives details of the electromagnetic emissions, and how these are classified,
for the device, and the electromagnetic environments in which the device is specified to technically
function.
