e. The numerics stop flashing after the parameter returns to within its Alarm Limits. If the
alarm system has been set to LATCHED, the numeric continues to flash after the
parameter returns to within its Alarm Limits, until the ALARM SILENCE control
key is pressed.
f. The numerics of the violated parameter flash on the screen and the audible alarm, once
silenced, will not sound again until after the alarm condition has been corrected. Only a
second (different) parameter alarm will cause the alarm sound to reactivate.
6.6 Adjusting the Alarm Tone Volume The Alarm Tone is adjusted in the SOUND ADJUST
Menu, which is accessed by selecting the SOUND ADJUST menu option in the SETUPS Menu.

Disabling the Alarm Tone The Alarm Tone may be disabled permanently in the ALARMS
Menu or it may be disabled temporarily by pressing the ALARM SILENCE control key.
a. The ALARM SILENCE control key has four functions as follows:
(1) WITH UNLATCHED ALARMS. If the alarm system has been set to
UNLATCHED in the ALARMS menu and an Alarm Limit is violated:
• It silences the alarm tone when an active Alarm Limit has been
violated.
WHILE THE PARAMETER CONTINUES TO VIOLATE ITS LIMITS:
• The numeric of the violated parameter will continue to flash on the
screen.
(2) WITH LATCHED ALARMS. If the alarm system has been set to
LATCHED in the ALARMS menu and an alarm is violated:
WHILE THE PARAMETER CONTINUES TO VIOLATE ITS LIMITS:
• It will silence the Alarm Tone.
• The numeric will continue to flash, even after the parameter returns
to within its Alarm Limits.
WHEN THE PARAMETER GOES BACK WITHIN LIMITS:
• It will silence the Alarm Tone, stops the numeric from flashing and
puts the Alarm System into the Alarm Hold mode.
WHEN THE ALARM HAS BEEN SILENCED AND THE PARAMETER
RETURNS TO WITHIN LIMITS:
• Pressing ALARM SILENCE will stop the numeric from flashing
and puts the Alarm System into the Alarm Hold mode.
NOTE
The Alarm Tone only applies to the DCU, there is no speaker on the WPU.
WARNING
Once an alarm condition has been silenced it will not sound again for any reason as long as that
alarm condition continues. For example, if a patients Heart Rate drops below the set limit and that
alarm is silenced, the alarm will never sound that condition again unless the Heart Rate returns to
within limits and then drops below the limit again.
