Message”. 

Electrode is off.

 

Check the electrode 
condition.

 

Lead cable is off. 

Check the connection 
between the lead cable and 
this equipment. 

Check the connection 
between the lead cable and 
the electrode. 

Faulty Lead cable. 

Replace the ECG cable with a 
new one. 

Electrode is peeling off.

Situation Cause 

Solution 

ECG waveform 
contains noise. 

Electrode gel is dry 

Replace the electrode with a 
new one. 

Electrode is peeling off. 

Electric blanket is used. 

Cover the electric blanket 
with a shield cover. 

AC filter setting of the 
receiving monitor is OFF. 

Set the AC filter up as ON.
