Selecting a new patient category
After selecting the patient category, the new patient category label appears in the header bar.
A patient category change does not affect the following settings: the patient and physician names, patient ID, birth
date, admit date, height, and weight.
To select a new patient category
1Press the Menu function key.
2Touch the Patient setup tab.
3Touch Patient category and then select the appropriate category (Adult, Pediatric, Neonate). The message
Changing category will change alarm settings and algorithmic processing appears.
4Touch OK.
To adjust the alarm volume
1Press the Alarms function key.
2Touch the Alarm volume button and select the desired volume level (Off, 5%, 10 to 100% in increments of
10%).
When the M540 is on wireless transport in an IACS configuration or in standalone mode and it loses its connection
to the ICS, the alarm volume setting is automatically set to 100%. The setting Off is no longer available until the
connection to the ICS is restored.
Pausing acoustic alarm signals (audio pause)
Active alarms can be paused, or silenced, at the M540 for two minutes. In addition to pausing alarms, the setting
of the quiet mode feature determines how subsequent alarm conditions are announced.
You can initiate an audio pause in several ways:
– From an M540 in standalone mode or on wireless transport
– From an ICS
– From the remote view of another Infinity monitor within the same monitoring unit
– From the Cockpit when the M540 is docked in an IACS configuration
– From a remote device when remote control and remote silence are activated at the remote device and the
Cockpit (refer to the IACS Monitoring Applications IFU)
– When first turning on the device

Pausing alarms at the M540
The following happens at the M540 when you pause active alarms:
– All acoustic alarm signals are paused for a maximum of about two minutes.
– The Audio paused message appears in the alarm message header of the Cockpit along with the timer and the
following symbol:
– The alarm message appears in the color corresponding to the alarm priority.
– The parameter field no longer flashes in the color corresponding to the alarm priority. It appears in solid color.
– The alarm bar no longer flashes for high-priority and medium-priority alarm conditions.
The behavior of new alarm condition while the systems is in an audio pause state is determined by the Quiet mode
setting.
To initiate an audio pause at the M540
Press the yellow key on the M540:
Pressing the key again cancels the audio pause period and all alarm events are reported as usual.
To initiate an audio pause remotely
Press the following key on the main menu bar of the ICS to audio pause alarms for all assigned patients:
Press the same button in the viewport area to pause alarm tones for an individual patient. For more information,
refer to the instructions for use of the ICS.
Refer to the instructions for use of any remote device within the same monitoring unit for instructions on how
to initiate an audio pause.
Pressing the key again cancels the audio pause period and all alarm events are reported as usual.

Pausing alarm monitoring temporarily
If the password-protected alarm pause feature is activated, you can pause alarm monitoring temporarily. The alarm
pause duration is adjustable from 1 minute to 5 minutes.
The following happens when you pause alarm monitoring:
– Acoustic and optical alarm signals for new alarm conditions are suppressed for all parameters until alarm mon-
itoring begins again
– Alarm signals for any active alarm condition stop immediately
– The alarming parameter field and alarm bar return to the pre-alarm state
– Alarm messages are removed from the alarm message field in the header bar
– The far right field of the header bar turns yellow and displays the alarm message All alarms pause, a timer,
and the following symbol:
To pause alarm monitoring temporarily
1Press the Alarms function key.
2Touch All alarms pause.
As soon as the alarm pause period ends, the M540 generates acoustic and optical alarm signals as needed.
To activate alarm monitoring after pausing
1Press the Alarms function key.
2Touch All alarms pause before the alarm pause period ends to cancel the alarm pause.
Activating or deactivating alarm monitoring
If the password-protected alarm pause feature is set to No timeout, the following happens when you deactivated
alarm monitoring:
– All acoustic and optical alarm signals for new alarm conditions are suppressed for all parameters until alarm
monitoring is manually activated again
– Acoustic alarm signals for any active alarm condition stop immediately
– The alarming parameter field and alarm bar return to the pre-alarm state
– Alarm messages are removed from the alarm message field of the header bar
– The far right field of the header bar turns yellow and displays a message that all alarms are off and the following
symbol appears:

To deactivate alarm monitoring
1Press the Alarms function key.
2Touch All alarms off.
To activate alarm monitoring after deactivating
1Press the Alarms function key.
2Touch All alarms off.
The M540 provides acoustic and optical alarm signals again when it detects a new alarm condition.
Setting the upper and lower alarm limits
You can configure the upper and lower alarm limits of a parameter manually to trigger acoustic and optical alarm
signals if a parameter goes above or below the set limits.
To set an individual parameter’s alarm settings
1Touch the parameter field (for example, HR) to access that parameter’s dialog.
2Touch the tab for configuring the parameter limits (for example, HR limits).
3Touch the upper or lower alarm limit.
4Touch the up or down arrow to change the alarm limit setting.
5Touch OK.
Archive function
The archive function setting determines what happens in response to an alarm limit violation. The available settings
are:
–Off – no event is stored and no recording is generated.
–Store – stores the event for later review.
–Record – stores the event for later review when in standalone mode or on wireless transport. Once the M540
is docked, any stored event is transferred to the alarm history of the IACS where you can request a manual
recording of the event.
–Str/Rec – generates a timed recording for an M540 docked in an IACS configuration and stores the event.
When the M540 is in standalone mode or on wireless transport, this setting stores an event for later review.
Once the M540 is docked, any stored event is transferred to the alarm history of the IACS where you can re-
quest a manual recording of the event.
