Activating the ECG Feature 
Note: The ECG inputs are defibrillation proof. However, in the event of defibrillation while using the 
ECG function, the ECG inputs may become saturated (overloaded). An ECG pattern may not be 
visible for up to 30 seconds. After this time, the ECG function should return to normal operation. 
To activate ECG: 
1.  Connect the six-pin ECG cable to the connector labeled "ECG" on the left front of the 
system. 
2.  Attach the ECG electrode patches to the patient in the locations specified below. 
3.  Connect each lead to the appropriate patch. 
The ECG trace is activated when you connect the ECG cable. 
Note: The system cannot display a trace unless all three leads are connected to a patient. 
4.  To dismiss the message that displays when an ECG lead becomes disconnected, click 
Close. Or, reconnect the disconnected ECG lead. 
In keeping with existing international standards, the ECG leads for systems that operate at 
115V (for example, North and South America) are red, white, and black. They are labeled 
RA (right arm), LA (left arm), and LL (left leg). Leads for systems that operate at 230V (for 
example, Europe) are green, red, and yellow. They are labeled R (right arm), L (left arm), 
and F (left leg).
