 technical alarm.
The SpO
2
numeric value is
replaced with a
.
SpO
2
measurements are
erratic.
Check that the sensor is applied properly.
Make sure the sensor site has a pulse.
Relocate the sensor to another site with improved
circulation.
Try another sensor.
 technical
alarm.
Excessive patient movement
or electrical interference.
Minimize patient movement.
Make sure the sensor cable is not positioned too close to
power cables.
 technical
alarm.
Ambient light is too high. Cover the sensor with an opaque material to minimize
ambient light.
Make sure the sensor cable is not positioned too close to
power cables.
Make sure that the sensor cable is not damaged.
 technical
alarm.
The sensor is not connected.
Check the SpO
2
connection.
Try another sensor.
There is too much
interference.
The sensor is damaged.

technical alarm.
The SpO
2
sensor or cable is
faulty.
Try another sensor.
If the problem persists, call for service of the SpO
2
module. If SpO
2
monitoring is essential to patient care,
take the device out of use.

technical alarm.
Faulty SpO
2
hardware. Call for service of the SpO
2
module. If SpO
2
monitoring is essential to patient care, take the device
out of use.

technical alarm.
The SpO
2
numeric value is
replaced with a
.
An NBP measurement or an
excessively noisy signal is
delaying display/update of
the SpO
2
measurement for
more than 30 seconds.
Wait until the NBP measurement is complete.
Try another sensor site.
Move sensor to a different limb than the NBP cuff.
 technical
alarm.
The SpO
2
numeric value is
replaced with a
.
The SpO
2
signal is too low
to give an accurate reading.
Check that the sensor is applied properly.
Make sure the sensor site has a pulse.
Relocate the sensor to another site with improved
circulation.
Try another sensor.
 technical alarm. A non-critical device failure
has occurred.
Restart device when it is appropriate to do so. If the
alarm continues, call for service of the SpO
2
module. If
SpO
2
monitoring is essential to patient care, take the
device out of use.
