WARNING
Using cables, transducers, or accessories with the system other than those speci-
fied for use with the system may result in increased emissions or decreased
immunity of the system.
ECG Signal
The amplitude of the electrocardiogram (ECG) signal is critical for reliable frame
triggering. Frame triggering should only be used when a clean, noise-free ECG
waveform is observed on the ECG display.
The ECG signal should be at least 0.25 mV to ensure reliable triggering when the
system is used in the presence of the electromagnetic phenomena described in
this manual.
WARNING
Operation of your system below 0.25 mV may cause inaccurate results. See
“ECG/Physio Input Connections” on page 142 for more information.
Electrostatic Discharge Precautions
Electrostatic discharge (ESD), commonly referred to as a static shock, is a natu-
rally occurring phenomenon. ESD is most prevalent during conditions of low
humidity, which can be caused by heating or air-conditioning. During low humidity
conditions, electrical charges naturally build up on individuals and objects and can
create static discharges.
