Repair Information Troubleshooting
Parameter Failure
MESSAGE/PROBLEM REASON SOLUTION
No ECG waveform Poor connection of ECG
electrodes
Use new electrodes to ensure
good contact
No square waveform exists
during CAL self-test
Replace ECG/RESP module
RL electrode is disconnected Connect RL electrode
ECG/RESP module is damaged Replace ECG/RESP module
ECG waveform interference or
abnormal ECG waveform
Electrodes are connected
incorrectly
Correctly connect electrodes
There are disconnected or
intermittent electrodes
Remove any electrodes that
are not used
AC power has no grounding
plug
Use grounded power cord
and outlet
ECG filter mode is incorrect Select appropriate filter mode
ECG/RESP module is damaged
or defective
Replace ECG/RESP module
No RESP waveform or
abnormal RESP waveform
Electrodes are connected
incorrectly
Use RA-LL
(R and F)
electrode, connect correctly
Patient is moving constantly Keep patient calm
ECG/RESP module is damaged
or defective
Replace ECG/RESP module
TEMP value is incorrect Temp sensor is poorly
connected
Reconnect TEMP sensor
HR value is inaccurate ECG waveform intermittent Check ECG connections and
reconnect
NIBP cuff cannot be inflated Airway is occluded or has
leakage
Adjust or repair the airway
Blood pressure intermittently
cannot be measured
Cuff becomes loose or patient is
moving
Keep the patient calm. Re-
wrap the cuff correctly and
safely
Blood pressure measurement is
inaccurate
Cuff size does not fit the patient Use the appropriate size cuff
NIBP module defective Replace NIBP module
