• You can switch off lethal arrhythmia alarms only when you have enabled Lethal Arrhys Off. For more
information, see 11.7.4.2Setting the Lethal Arrhythmia Alarms Switch.
• The priority of lethal arrhythmia alarms is always high. It cannot be altered.
11.7.4.2 Setting the Lethal Arrhythmia Alarms Switch
You can choose whether switching off lethal arrhythmia alarms is permissible or not. This function is password
protected. For more information, see 39.4.6The Other Tab.
• If you switch off all arrhythmia alarms, the monitor will not alarm for any arrhythmia event. This may
result in a hazard to the patient. Always keep the patient under close surveillance.
• If any of the lethal arrhythmia alarms is switched off, the ECG waveform area displays the “Lethals
Off” message.

You can change threshold settings for some arrhythmia alarms. When an arrhythmia violates its threshold, an
alarm will be triggered. To do so, follow this procedure:

2. Select the Arrhythmia tab → select the Threshold tab.
3. Enter the password if required. For more information, refer to 39.13The Authorization Setup Settings.
4. Set the threshold of desired arrhythmia alarms.
• The asystole delay time relates to ECG relearning. When heart rate is less than 30 bpm, it is
recommended to set Asystole Delay to 10 sec.
