WARNING Electrical shock hazard. Do not touch accessible connector pins and the patient
Ensure that the electrodes or lead wires do not come in contact with any other conductive
materials (including earth-grounded materials) especially when connecting or disconnecting
electrodes to or from a patient.
Main Waveform Display Screen
Manual measurements of ECG intervals and magnitudes should be performed on printed
ECG reports only. Do not make manual measurements of ECG intervals and magnitudes on
the main waveform display screen since these ECG representations are scaled.
Modem Card and Fax Feature
Do not connect the modem card to a phone line when the cardiograph is connected to a
No guarantee is made as to the suitability of a faxed ECG report for any particular purpose,
due to the variability inherent in fax technology.
Pace pulses may not be visible on a printed ECG report that uses simultaneous acquisition.
Patient Data Cable
Keep the patient data cable away from power cords and any other electrical equipment.
Failure to do so can result in AC power line frequency interference on the ECG trace.
The Philips Medical Systems patient data cable (supplied with cardiograph) is an integral
part of the cardiograph safety features. Use of any other patient data cable may compromise
defibrillation protection and degrade cardiograph performance.
Periodically inspect the patient data cable for any cracks or breaks in the cable insulation. If
the integrity of the patient data cable is not assured, replace the patient data cable. Contact
Philips Medical Systems for further assistance.
