
If the lead cable or relay cable is defective (wire break, etc.), replace it.

If any noise source is near the patient, move it away from the patient as far as possible.
Cause 2
EMG is interfering.
Solution

Change the electrode site to a location where the myoelectricity will be less likely to interfere.

Select ESIS for the filter mode.
 Selecting ESIS for the filter mode will decrease the QRS amplitude and may result in
not counting the heart rate.
Cause 3
Even though the "3-lead Override" (ECG Parameter Setup) is set to [ON], electrodes other than L (LA), R (RA), F
(LL) are connected.
Solution
Set the "3-lead Override" to [OFF].Or, detach the electrodes other than L (LA), R (RA), F (LL).

The ECG waveform is in the baseline position.
The lead-off condition may have occurred by the following causes.
Cause 1
Electrode is detached.
Solution
Place the electrodes again.If the electrode contact is poor, replace the electrode.
Cause 2
The lead cable is disconnected from the electrode terminal.
Solution
Securely connect the lead cable.
 If the error persists, wire break of the lead cable or relay cable can be considered.

<Check Electrodes Attachment> is displayed.
Cause 1
The electrode contact with the skin is poor. There is substantial contact resistance between the electrodes.
Solution
Replace all the electrodes.Make sure to use the same type of electrodes .
Cause 2
Even though the "3-lead Override" (ECG Parameter Setup) is set to [ON], electrodes other than L (LA), R (RA), F
(LL) are connected.
Solution
Set the "3-lead Override" to [OFF]. Or, detach the electrodes other than L (LA), R (RA), F (LL).
