4 Patient Alarms and INOPs Technical Alarm Messages (INOPs)
72
<SpO
2
label> DEACTIVATED
INOP tone
SpO
2
You have connected a measurement server that uses a label the
monitor has already assigned to a different source. To activate
the new source, choose a new label in the Measurement
Selection window.
<SpO
2
label> EQUIP MALF
Numeric is replaced by -?-
INOP tone.
SpO
2
The MMS is faulty. Unplug and replug the MMS. If the INOP
persists, contact your service personnel.
<SpO
2
label> ERRATIC
Numeric is replaced by -?-
INOP tone.
SpO
2
Check the sensor placement. Try another adapter cable and
sensor. If the INOP persists, contact your service personnel.
<SpO
2
label> EXTD. UPDATE
Label is displayed with a -?-
(questionable numeric)
SpO
2
The update period of displayed values is extended due to an
NBP measurement on the same limb or an excessively noisy
signal.
<SpO
2
label> INTERFERNCE
Numeric is replaced by -?-
INOP tone.
SpO
2
There is too much interference, caused by a high level of
ambient light and/or electrical interference. Cover the sensor to
minimize ambient light. If the INOP persists, make sure that
the sensor cable is not damaged or positioned too close to
power cables.
<SpO
2
label> LOW PERF
Label is displayed with a -?-
(questionable numeric)
SpO
2
Accuracy may be compromised due to very low perfusion.
Stimulate circulation at sensor site. If INOP persists, change
the measurement site.
<SpO
2
label> NOISY SIGN.
Numeric is replaced by -?-
INOP tone.
SpO
2
Excessive patient movement or electrical interference is causing
irregular pulse patterns. Try to reduce patient movement or to
relieve the cable strain on the sensor.
<SpO
2
label> NON-PULSAT.
Numeric is replaced by -?-
INOP tone.
SpO
2
Check the perfusion at measurement site. If necessary,
stimulate circulation or change measurement site. If the INOP
is due to NBP measurement on the same limb, wait until the
NBP measurement is finished.
<SpO
2
label> NO SENSOR
Numeric is replaced by -?-
INOP tone.
SpO
2
Make sure the SpO
2
sensor is connected. If the INOP persists,
try another adapter cable and sensor. If you silence this INOP,
the measurement will be switched off.
<SpO
2
LABEL> POOR SIGNAL
Label is displayed with a - ? -

SpO
2
The signal condition of the SpO
2
measurement is poor and
measurement accuracy may be compromised.
<SpO
2
LABEL> PULSE?
Numeric is replaced by -?-
INOP tone
SpO
2
The detectable pulsations of the SpO
2
signal are outside the
specified pulse rate range.
<SpO
2
LABEL> SEARCHING
Numeric unavailable
SpO
2
SpO
2
is analyzing the patient signal to derive Pulse, SpO
2
and
Perf values. Please wait until the search analysis is complete.
<SpO
2
label> SENSOR MALF
Numeric is replaced by -?-
INOP tone.
SpO
2
The SpO
2
sensor or adapter cable is faulty. Try another adapter
cable and sensor. If the INOP persists, contact your service
personnel.
<SpO
2
LABEL> SENSOR OFF
Numeric is replaced by -?-
INOP tone
SpO
2
The SpO
2
sensor is not properly applied to the patient. Apply
the sensor following the instructions supplied by the
manufacturer.
<SpO
2
LABEL> UNKN.SENSOR
Numeric is replaced by a - ? -
SpO
2
The connected sensor or adapter cable is not supported by the
SpO
2
measurement. Use only specified sensors and cables.
