Alarm Latching Behavior
All INOPs are non-latching. See “Yellow Arrhythmia Alarms” on page 134 for information on one-
star yellow alarms latching behavior.
Testing Alarms
When you switch the monitor on, a selftest is started. You must check that the alarms lamps light, one
after the other, 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 (for example SpO
2
or CO
2
) or use a simulator. Adjust alarm limits and check
that appropriate alarm behavior is observed.
Alarm Behavior at Power On
If the monitor is switched off for longer than one minute and then switched on again (or after a loss of
power lasting longer than one minute, or when a patient is discharged), the monitor can be configured
to:
• restore the alarm settings from the monitor's configured default Profile,
• restore the most recently used alarm settings, or
• switch the alarms off.
After any of these situations, you should check that the alarm settings are appropriate for your patient
and monitoring situation, and if necessary, select the correct Profile and patient category.
If power is lost for less than one minute, the alarm on/off condition prior to the power loss is
restored.
