Defibrillator/Monitor Operator’s Manual 4 - 7
â– The parameter numeric and alarm limits still flash.
Technical alarms give different alarm indicators when the alarm system is reset:
■For some technical alarms, including the NIBP-related alarms, a √ appears before the alarm message and
the alarm reset symbol
appears in the alarm symbol area.
â– Some technical alarms are changed to the prompt messages.
â– Some technical alarms are cleared. The equipment gives no alarm indications.
For details about the indications of technical alarms when the alarm system is reset, refer to E.2Technical Alarm
Messages.
4.10 Latching Alarms
The latching setting for physiological alarms defines how alarm indicators behave if you do not reset the alarms.
â– If an alarm is latched, alarm indications remain presented even though alarm conditions end, except that:
â—† The parameter reading and violated alarm limit stop flashing.
â—† The time when the alarm is last triggered is displayed behind the alarm message.
â– If an alarm is not latched, the alarm indications disappear as soon as the alarm conditions end.
To latch a physiological alarm:
1. Press the Main Menu button on the front panel, and then select [Others >>] → [Configuration >>] →
enter the required password.
2. Select [Alarm Setup] and set [Latching Alarms] to [Ye s ].
Only physiological alarms can be latched. You can clear the latched alarms by pressing the Alarm Pause button
on the front panel .
4.11 Clearing Technical Alarms
Technical alarms give different alarm indicators after the Alarm Pause button or [Alarm Reset] soft key is
pressed. The technical alarms are classified into three categories for easy clarification:
â– Technical alarms are cleared.
All alarm indications are cleared after the Alarm Pause button or [Alarm Reset] soft key is pressed.
After the equipment restores the normal alarm status, it can give alarm indications correctly in case these
alarms are triggered again.
â– Technical alarms are changed to the prompt messages.
The alarm lamp flashing and alarm tones are cleared and the alarm messages change to prompt messages
after the Alarm Pause button or [Alarm Reset] soft key is pressed. After the equipment restores the
normal alarm status, it can give alarm indications correctly in case these alarms are triggered again.
■The alarm is silenced and a √ appears before the alarm message.
The alarm tones are cleared but the alarm lamp flashing and alarm messages remain after the Alarm Pause
button or [Alarm Reset] soft key is pressed. After the equipment restores the normal alarm status, all
the alarm indications will continue if the alarm conditions still present.
4.12 Testing Alarms
W
hen the equipment starts up, a selftest is performed. In this case the alarm lamp is lit in yellow and red
respectively, and the equipment gives a beep. This indicates that the visible and audible alarm indicators are
functioning correctly.
For further testing of individual measurement alarms, perform the measurement on yourself (for example SpO
2
or CO
2
) or use a simulator. Adjust alarm limits and check that appropriate alarm behaviour is observed.
