Audible Alarm Indicators

• Red alarms: A high pitched sound is repeated once a second. 

• Two-star yellow alarms: A lower pitched sound is repeated every two seconds.

but of shorter duration.

• INOPs: an INOP tone is repeated every two seconds.

ISO/IEC Standard 9703-2 Audible Alarms

• Red alarms: A high pitched tone is repeated five times, followed by a pause. 

• Two-star yellow alarms: A lower pitched tone is repeated three times, followed by a pause. 

• One-star yellow alarms (arrhythmia alarms): The audible indicator is the same as for yellow alarms, 

but of shorter duration.

♦

The alarm volume symbol at the top right of the monitor screen gives you an 
indication of the current volume. To change the volume, select the volume symbol 
and then select the required volume from the pop-up selection.

♦

If you want to see a numerical indication of the current alarm volume on a scale 
from zero to 10, select the 

 SmartKey. The volume scale pops up. 

The current setting is indented. To change the setting, select the required number 
on the scale. Any settings that are inactive (“grayed out”) have been disabled in the 
monitor’s Configuration Mode.

When the alarm volume is set to zero (off), the alarm volume symbol reflects this. If you 
switch the alarm volume off, you will not get any audible indication of alarm conditions.

If your monitor is connected to an Information Center, and the connection is interrupted, the INOP 
message 

will appear within 30 seconds, accompanied by an INOP tone. To 

help ensure that this INOP, and any other active alarm, is not overlooked, the INOP and alarm tones 
may be configured to have a minimum volume. In this case, INOP and alarm tones will sound even if 
the monitor alarm volume is set to zero.
