4.3.4 Controlling Alarm Volume
The monitor provides five levels of alarm volume: 1, 2, 3, 4 and 5. For adjusting the alarm
volume, please refer to Section Adjusting Alarm Volume.
4.4 Latching Alarms
To set the alarm latch function, please select Menu > Maintenance > User Maintain > Alarm
Setup and set Alarm Latch from the pull-down list. If it is set to On, when an alarm occurs, the
monitor will display the alarm message of the parameter in the alarm status area. If the parameter
resumes to normal, the alarm information of this parameter still displays in the alarm display area
and the alarm time is also displayed. If many parameters appear to be latching alarms, the alarm
messages are displayed in the physiological alarm message area in turn.
To deselect the alarm latch, please set Alarm Latch to Off. When Alarm Latch is set to Off, the
latch function is invalid.
4.5 Disabling Sensor Off Alarms
To set sensor off alarm, please select Menu > Maintenance > User Maintain and enter the
required password ABC. Then select Alarm Setup and set Sensor Off Alm from the pull-down
list. If it is set to On, and a sensor off alarm occurs, the user can press the Mute key on the front
panel to disable the alarm signal. Then the alarm indicator stops flashing, and the monitor is in
temporary mute alarm status. If the user presses the Mute key again or the temporary mute time
ends, no audible alarm for sensor-off status will be resumed. Instead, sensor-off status will be
announced with a prompt message.
4.6 Testing Alarms
When you switch the monitor on, a self test is started. You must check that the alarm indicator
lights and that you hear a single tone. This indicates that the visible and audible alarm indicators
are functioning correctly. For further testing of individual measurement alarms, perform the
measurement on yourself or use a simulator. Adjust alarm limits and check that appropriate alarm
behavior is observed.
