Using the 9847 Pulse Oximeter
Audible Indicators
Audible Indicators include medium priority equipment and high priority patient alarms, and informational
tones (breath beeps). For information on disabling the audible alarms, see “Disabling the Audible Alarms”
on page 17.
Audible and Visible Indicator Functions During Alarm Conditions
Table 4 summarizes the audible and visible indications that occur during the equipment and patient alarm
conditions.
NOTE:
These rules assume that the audible alarms have not been temporarily or permanently
disabled using the “audible alarm disabled” switch.
CAUTION:
Do not block the audible indicator speaker holes. Blocking the speakers
will significantly reduce the sound volume.
CAUTION:
Verify that the audible alarms can be heard over the ambient noise of the
operating environment.
