Audible Indicators

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.
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.
