NOTE
M3500B/M5500B Service Manual
Immunity Level
The EMC standards state that manufacturers of patient-coupled equipment
must specify immunity levels for their systems. It is recognized that the
M3500B/M5500B defibrillator/monitor is designed to receive and amplify
low level signals in the same bandwidth as the interference.
Immunity is defined in the standard as the ability of a system to perform with-
out degradation in the presence of an electromagnetic disturbance. Degrada-
tion in ECG quality is a qualitative assessment which can be subjective.
Caution should, therefore, be taken in comparing immunity levels of different
devices. The criteria used for degradation is not specified by the standard and
may vary with the manufacturer.
