Alarm message Default priority
Indication on 
alarm reset
Cause and solution
ECG Noisy Low/Prompt A The ECG signal is noisy. Check for any possible 
sources of signal noise around the cable and 
electrode, and check the patient for excessive 
motion.
ECG Amplitude Too Small Low C The ECG amplitude does not reach the detected 
threshold. Check for any possible source of 
interference around the cable and electrode.
ECG Lead Off Low B The electrode has become detached from the 
patient or the lead wire has become 
disconnected from the adapter cable. Check the 
connections of the electrodes and leadwires.
ECG XX Lead Off Low B The electrode has become detached from the 
patient or the lead wire has become 
disconnected from the adapter cable. Check the 
connections of the electrodes and leadwires.
ECG Signal Invalid Low A Patient skin impedance is too high. Check ECG 
electrode application. 
ECG Learning Prompt / ECG learning is manually or automatically 
triggered.
Cannot Analyze QT Prompt / /
D12L not available Prompt C The current Va and Vb combination does not 
support D12L. Choose an available Va and Vb 
combination. For more information, see
