RECOMMENDED ACTIONS:
If you are not above 40º C, or below 10º C, this indicates a failure or calibration error in the Atlas Monitor
temperature sensing system. The unit must be repaired.
MESSAGE:
SpO
2
cable not detected
MEANING:
Atlas Monitor has lost communication with the SpO
2
cable and sensor.
RECOMMENDED ACTIONS:
Check the connection where the SpO
2
cable attaches to the Atlas Monitor.
Check the connection between the SpO
2
extension cord and the SpO
2
sensor, if used.
Check the connection between the SpO
2
sensor and the SpO
2
cable.
Replace the SpO
2
sensor and cable.
If none of these solves the problem, the unit must be repaired.
MESSAGE:
SpO
2
sensor not detected
MEANING:
Atlas Monitor has lost the pulse signal from the SpO
2
sensor. The Atlas Monitor can still detect that the
sensor and cable are attached, but does not detect a patient’s pulse.
RECOMMENDED ACTIONS:
Check attachment of sensor to patient.
Block ambient light infiltration into sensor – cover with gauze or other opaque material.
Check for health and condition of sensor attachment point.
Move sensor to a new attachment point.
Check patient for physiological problems – anoxia, anemia, defective hemoglobin, poor peripheral
circulation, restricted blood flow to limb.
Check fingernail for polish or other coverage that may block sensors ability to acquire measurement.
Check that blood pressure cuff is not on the same limb as the SpO
2
sensor.
Replace SpO
2
sensor and cable.
If none of these solves the problem, the unit must be repaired.
MESSAGE:

MEANING:
Atlas Monitor has detected a malfunction of the SpO
2
system.
RECOMMENDED ACTIONS:
An electrical fault has been detected in the SpO
2
system. Remove the Atlas Monitor from service. The
unit must be repaired.
