E.2 Technical Alarm Messages
ECG Irr. Rhythm M* Arrhythmia has occurred to the patient. Check the patient’s
condition and the ECG connections.
A-Fib M*
PNP M* The pacer appears abnormal. Check the pacer.
PNC M*
Resp Resp Apnea H The respiration signal was so weak that the equipment cannot
perform respiration analysis. Check the patient’s condition and the
Resp connections.
Resp Artifact H The respiration circuit is disturbed. Check for any
possible sources of signal noise.
SpO2
SpO2 Desat H The SpO
2
value has fallen below the desaturation alarm limit.
Check the patient’s condition and check if the alarm limit settings
are correct.
No Pulse L The pulse signal was so weak that the equipment cannot perform
pulse analysis. Check the patient’s condition, SpO
2
sensor and
measurement site.
CO2
CO2 Apnea H The patient stops breathing, or the respiration signal was so weak
that the equipment cannot perform respiration analysis. Check the
patient’s condition, CO
2
accessories and airway connections.
Measurement Alarm Message L Cause and solution
Measurement Alarm Message L I Cause and solution
XX XX SelfTest Err H C
An e
rror occurred to the XX module, or there is a problem
with the communications between the module and the

XX Overrange L C The measured XX value is not within the specified range
for XX measurement. Contact your service personnel.
ECG ECG Lead Off L* B The ECG electrode has become detached from the patient
or the lead wire has become disconnected from the trunk
cable. Check the connection of the electrodes and
leadwires.
ECG YY Lead Off
(YY represents the
leadwires V, LL, LA, and
RA, as per AHA
standard, or C, F, L and R
as per IEC standard.)
L* B
Pads/Paddles Off L* B The pads/paddles have been detached from the patient
or the therapy cable is loose. Check that the electrode
pads/paddles and therapy cable are properly connected.
ECG Noise L A The ECG signal is noisy. Check for any possible sources of
signal noise form the area around the cable and electrode,
and check the patient for excessive motion.
ECG Signal Invalid L A ECG amplitude is so low that ECG signal is undetectable.
Check for any possible source of interference from the
area around the cable and electrode; check the patient’s
condition.
