The intensity changed considerably since the last light intensity
calibration. This may indicate that the catheter tip is positioned
against a blood vessel wall or that there is low blood flow.
Reposition the catheter (and perform a Light Intensity
Calibration).
<SO

Label> LOW LIGHT
Numeric is replaced by -?-
INOP tone.
SO

The optical signal levels are too low. Check that the catheter is
either in the optical reference or inserted into the patient.
Check the catheter-to-Optical Module connection. If INOP
persists, try another catheter and Optical Module.
<SO

Connect the Optical Module. If the INOP persists, try another
Optical Module. Silencing this INOP switches the
measurement off.

The Optical Module memory is faulty, and calibration data
cannot be stored for transport or during power failure. If this
capability is needed, use another Optical Module.

The pre-insertion calibration is running. This typically takes
one minute. During this time alarms are switched off. Wait
until the calibration is complete.

module is currently in upgrade mode.
Monitoring is not possible in this mode.

Label> WARMUP
Numeric is displayed with ?

The Optical Module has not yet reached the operating
temperature. Wait a few minutes until warm-up is finished.
SOME ECG ALRMS OFF Arrhythmia This message appears (if configured to do so) when the on/off
settings of the yellow arrhythmia alarms differ from the current
Profile.
Speaker Malfunct.
INOP tone
Monitor Contact your service personnel to check the speaker and the
connection to the speaker.
SPIRO MALFUNCTION Spirometry Module failure detected. Contact your service personnel.
SPIRO INCOMPATIBLE Spirometry Module revision not compatible with the host monitor
software revision. Contact your service personnel.
SPIRO UPGRADE Spirometry The module is running a firmware upgrade. Wait until upgrade
is completed before resuming monitoring.
SPIRO CANNOT MEAS Spirometry Measurement is at its limit, e.g. ambient pressure out of range.
SPIRO PURGE FAILED Spirometry The purge operation could not be completed successfully.
Check for kinked sensor tubings, hard occlusions and make
sure that the pump is running and all valves are switching.
SPIRO UNKN. SENSOR Spirometry An unknown sensor ID code was detected. Use only the sensors
listed in the Accessories chapter.
SPIRO ALARMS SUPPR Spirometry Alarming is suppressed for the spirometry module.
SPIRO PURGING Spirometry A purge operation is in progress - no data update on the screen.
Wait until purge is complete.
SPIRO NO SENSOR Spirometry No sensor detected. Make sure the correct sensor is attached to
the breathing circuit.
