Physiologic Function 
  WARNING: Use ECG for timing purposes only. It is not intended for diagnostic usage or patient 
monitoring. 
  WARNING: Do not use the ECG feature in conjunction with electrosurgery or diathermy 
equipment. 
  WARNING: To reduce the risk of electric shock and burns, use only the cable and patient leads 
supplied with the ECG feature. Use of other ECG cables could defeat the current-limiting and 
electrical safety features of the ECG. 
  Caution: To avoid possible damage to the ECG cable, do not pull on the cable when 
disconnecting the ECG connector. Always grasp the connector housing. 
The Physio module consists of the ECG feature. 
The ECG feature includes three leads attached to a six-pin ECG cable, along with a start-up kit 
of ECG electrode patches. 
The electrical activity controlling the heart muscle is detected by placing ECG electrode patches 
in specific locations on the patient and amplifying the electrical signals that produce the ECG 
trace display on the system monitor. 
EMC Note: Operating the ultrasound imaging system in close proximity to sources of strong 
electromagnetic fields, such as radio transmitter stations or similar installations, may lead to 
interference visible on the monitor screen. However, the device has been designed and tested to 
withstand such interference and will not be permanently damaged.
