Alarm Violations
An alarm condition exists if the physiological parameter is equal to or is outside the high/low
limit range that has been set. When an alarm limit is violated, the following actions occur:
• The LEDs for the parameter in an alarm condition flashes.
• The parameter in an alarm condition is in reverse video on the LCD (Accutorr Plus
advanced models).
• The alarm tone is sounded (unless muted with the MUTE key (30)).
• The parameter(s) that was in an alarm condition will be in brackets [ ] when printed on
the recorder.

How to Mute Alarms
When an NIBP alarm exists, press the
MUTE
key (30) (1 beep tone) to silence the alarm tone
for 2 minutes. The alarm tone will return after the next measurement value that violates the
selected limits.
When an SpO
2
alarm exists, press the
MUTE
key (30) (1 beep tone) to silence the alarm
tone for two minutes. The alarm tone will return after two minutes, unless the SpO
2
value
changes and is within the alarm limits. If during that two minutes the measured SpO
2
value
changes to a value that is within the acceptable range, and then returns to a value that is
outside the set alarm limit, the alarm tone will return before the two minutes elapse. Example
(within 2 minutes): • SpO
2
low alarm limit has been set to 90. • SpO
2
is measured at 89;
the alarm tone sounds and the SpO
2
display flashes. • The MUTE key is pressed. • SpO
2
is
measured at 88; there is no alarm tone, but the SpO
2
display flashes. • SpO
2
is measured at
91; no alarm tone sounds and the display stops flashing. • SpO
2
is measured at 89; the
alarm tone sounds and the SpO
2
display flashes.
Press and hold the
MUTE
key (30) (2 beep tones, approx. 3 seconds) to permanently silence
the alarm tone. The MUTE LED (31) illuminated. The LEDs for the alarming parameter will
continue to flash. To reactivate the alarm tone function, press the
MUTE
key (30) again.

Alarms and Changing the Room Number and/or Bed Letter
When changing the rooms and beds, the alarm settings will change if the final room/bed
displayed is a different patient size than the original room/bed. When a new patient size is
detected, the alarm settings change to the defaults for the different patient size. See section
3.15 for information on custom defaults.
The table below describes 6 measurements in different rooms/beds and different patient
sizes, and the effect on the alarm settings.
