8.7.2 Changing Arrhythmia Alarm Settings 
To change arrhythmia alarm settings, select the ECG parameter area or waveform area 
[ECG Setup] [Arrh. Analysis >>]. In the pop-up menu, you can set the [Alm Lev] to 
[High], [Med], [Low] or [Message], or switch on lethal arrhythmia analysis alarms only or 
switch on/off all arrhythmia analysis alarms. In the [Alarm Setup] menu from the [User 
Maintenance] menu, you can enable/disable turning off lethal arrhythmia analysis alarms.   
 
 
 WARNING 
z  If you switch off all arrhythmia analysis alarms, the monitor cannot give any 
arrhythmia analysis alarm. Always keep the patient under close surveillance. 
z  The priority of lethal arrhythmia alarms is always high. It is unchangeable. 
 
 
8.7.3 Changing Arrhythmia Threshold Settings 
Select the ECG parameter window or waveform area[Arrh. Analysis >>][Arrh. 
Threshold], and you can then change threshold settings for some arrhythmia alarms. In case 
an arrhythmia violates its threshold, an alarm will be triggered. The asystole delay time 
relates to ECG relearning. When HR is less than 30 bpm, it is recommended to set the 
asystole delay time to 10 seconds.
