120 seconds.

To continuously silence the alarms, see Section 4 Setup Menu Level 1.
Alarm Silenced Indicator
The Alarm Silenced Indicator provides visual feedback regarding the audible alarm status. The audible
alarms are muted when the indicator is flashing or continuously illuminated.
While monitoring a patient, acknowledging an alarm condition by pressing the Alarm Silence Button
(one time) will silence the alarm tone for 120 seconds and the Alarm Silenced Indicator will flash.
Pressing the Alarm Silence Button a second time (while the Alarm Silenced Indicator is still flashing)
will activate alarms and the alarm silence indicator will be off.
If the alarms have been silenced, per Setup Menu Level 1, then the Alarm Silence indicator will be
continuously illuminated. The Alarm Silence indicator will remain illuminated until after a power cycle
or until the alarms are enabled (see Section 4, Setup Menu).
While not monitoring a patient, acknowledging an alarm condition by pressing the Alarm Silence Button
(one or more times) will permanently silence the alarm tone, and the Alarm Silenced Indicator will
remain illuminated until the power is cycled or patient monitoring begins.
Should the alarm condition be created by low batteries, replace the batteries before monitoring begins
or continues.
