The “ Pacemaker error ” message is displayed. Cause: The pacemaker pulse is detected 16 pulses or more per second. Solution 1: Attach the electrodes firmly. ? Replace the lead cable if defective. ? If any noise source is near the patient, locate it away from the patient as much as possible. The “ ECG not connected ” message is displayed. Cause: When the ECG relay cable is disconnected during ECG monitoring, this message will be displayed. Solution 1: To cease monitoring, press the Alarm Silenc e key to clear the message and silence the alarm. Solution 2: To conti nue monitoring, plug in the ECG relay cable. This will clear the message and silence the alarm. Cause: Heartbeat is interfering and superimposed on the respiration waveform. Solution: Place the ele ctrode as shown below where the heartbeat will be less likely to interfere. “ 0 ” is displayed for respiration rate, or apnea alarm is generated. Cause: The respiration waveform amplitude is below the detection level ( 0.2O ). Solution: Change the electrode site. The respiration waveform and respiration rate is not displayed. Cause 1: The ECG relay cable designed for electrosurgical knife is used. Solution: The impedance respiration can not be measured if the cable design ed for electrosurgical knife is used. Use the standard ECG relay cable if not using the electrosurgical knife. Cause 2: The impedance respiration measurement is ceased. Note: If the pacemaker with the minute ventilation measuring function is used, turn OFF the impedance respiration measurement. Otherwise, both the pacemaker and the monitor will not be able to perform accurate measurement. The measured data is displayed as “ ??? ”. Cause: The respiration rate is outside the measurement range. Invasive Blood Pressure The “ BP1 Transducer OFF ”, “ BP2 Transducer OFF ” message is displayed.

Change the electrode site to a location where EMG will less likely to interfere. ? Select ESIS mode for the filter mode. Note: Selecting a ESIS mode for the filter mode will decrease the QRS amplitude and may result in not counting the heart rate. The “ Check electrode ” message is displayed. Cause: The electrode contact with the skin is poor. There is substantial contact resistance between the electrodes. Solution: Replace all the electrodes. Use the electrodes of the same type. The “ ECG unit error ” message is displayed. Cause: A communication error with the ECG measuring unit exists. Solution: The breakage of wire or failure of the ECG unit can be considered. Contact our service representative. 10 Troubleshooting Solution: ? Check the electrode application. ? Replace the electrode, or check the lead cable. Heart rate is not counted. Heart rate is low. Cause: The ECG waveform amplitude is below the QRS d etection level (0.3mV). Solution: Change the electrode site, or select a lead with higher QRS amplitude. Also, if large amount of noise is interfering, the noise may be erroneously detected as QRS. It is recommended to change the electrode site and increase the ECG amplitude. Heart rate is not counted, and “LEAD OFF” message is displayed. Cause: The electrode of the displayed lead type is detached, or is not making good electrical contact with the skin. Solution: ? Check the electrode application. ? Replace the electrode, or check the lead cable. Artificial pacemaker is not displayed. Solution: Select Used for the pacemaker use.
