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

–Max. – provides maximum sensitivity for poor sig-
nals (this mode is recommended for patients with
low perfusion or when the low perfusion or low sig-
nal quality message is displayed in APOD or
Normal sensitivity mode. Max. mode is not recom-
mended for care areas where patients are not
monitored visually, such as general wards. It is de-
signed to interpret and display data at the measur-
ing site when the signal may be weak due to
decreased perfusion.)
