Welch Allyn CP 150 12-lead resting electrocardiograph v.1.00.XX - User Manual - Manual (Page 14)

CAUTION The requirements of AAMI EC11, Section 3.2.7.2, Frequency
and Impulse Response, for an impulse triangle waveform may be impacted
by up to 5 milliseconds of small amplitude dampened ringing immediately
after the impulse when the muscle filter (35 Hz) is turned on or a small
amplitude offset when the baseline filter (0.5 Hz) is turned on. These filters,
in any combination turned on or off, meet the AAMI requirements.
Measurements performed by the optional interpretation algorithm are
unaffected by any filter selections.
Note The entire patient cable, up to and including the electrodes are considered
to be an Applied Part.
