6.7 Technical Alarm Messages

Measurement Alarm Message Cause and solution

XX XX SelfTest Err An error occurred to the XX module, or there is a problem with the communications between the module and the host. Restart the equipment.

XX Init Err XX Comm Err XX Comm Stop

XX Overrange The measured XX value is not within the specified range for XX measurement. Check input signal and equipment setting.

ECG ECG Lead Off 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.)

Pads/Paddles off The pads/paddles have been detached from the patient or the therapy cable is loose. Check that the

pads/paddles and therapy cable are properly connected.

ECG Noise 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 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.

SpO2 SpO2 Sensor Off The SpO₂ sensor has become detached from the patient or the module, or there is a fault with the SpO₂ sensor, or an unspecified SpO₂ sensor has been used. Check the sensor application site and the sensor type, and make sure the sensor is not damaged. Reconnect the sensor or use a new sensor.

SpO2 Sensor Fault SpO2 No Sensor SpO2 Unknow sensor to a place with lower level of ambient light or cover the sensor to minimize the ambient light.

Measurement Alarm Message Cause and solution

SpO2 Low Signal The SpO2 signal is too low or too weak. Check the patient’s condition and change the sensor application site. If the error persists, replace the sensor.

SpO2 Weak Signal SpO2 Weak Pulse SpO2 Low Perf

SpO2 Interference The SpO2 signal has been interfered. Check for any possible sources of signal noise form the area around the sensor, and check the patient for excessive motion.

SpO2 Non-Pulsatile

SpO2 Board Fault There is a problem with the SpO₂ measurement board.

Replace the SpO₂ module.

Main control system

No Fan Make sure that the fan is connected.

No Speaker Make sure that the speaker is connected.

No Data Card Make sure that the CF card is in place or format the CF card.

Power Board Comm Err

An error occurred to the power board, or there is a problem with the communications between the power board and the host. Restart the equipment.

Keyboard Comm Err

An error occurred to the keypad board, or there is a problem with the communications between the keypad board and the host. Restart the equipment.

Therapy Module Comm Err

An error occurred to the therapy module, or there is a problem with the communications between the therapy module and the host. Restart the equipment. If the problem persists, replace the therapy module.

Main Control Selftest Err

The main control voltage is abnormal. Replace the main control board.

RT Clock Need Reset

Reset system time.

RT Clock Err An error occurred to the RTC chip, or the button cell is depleted. Replace corresponding part.

Data Card Err There is a problem with the data card. Check or replace the data card if necessary.

Power board Power System Selftest Err

An error occurred to the system power supply. Restart the equipment.

Power Board Volt Err

Low Battery Change battery or connect the equipment to the AC power source to charge the batteries.

Measurement Alarm Message Cause and solution

Battery Err There is a problem with the batteries. Check the batteries for damage; verify that correct batteries are used. Replace the batteries if necessary.

Battery Depleted!

System will shut shown imminently.

Connect to AC Mains or Replace Battery.

Connect the equipment to AC mains.

Battery Aged Replace the battery.

Battery failed charging

Battery failure or power board hardware failure.

Replace the battery. If the problem persists, replace the power board.

Therapy module

Therapy Equip selftest Err

An error occurred during therapy module self test.

Restart the equipment or replace the therapy module.

Defib Malfunction The defibrillation function fails or both the defibrillation and pacing functions fail. Restart the equipment and test defibrillation function. If the problem persists, replace the therapy module.

Pacer Malfunction! The pacing function fails. Restart the equipment and test pacer function. If the problem persists, replace the therapy module.

Disarming Failed There is a problem with the therapy module disarming circuit. Replace the therapy module.

Last User Test Failed

Run a succesful user test.

Last Auto Test Failed

Run a succesful user test again.

Monitoring module

Mornitor Module Selftest Err

An error occurred during MPM module power-on self test. Replace the MPM module.

Mornitor Module Reset Err

MPM module reset abnormally. In this case, the MPM module restores to default configuration. You can ignore this problem.

Mornitor Module Voltage Err

The voltage of MPM module is abnormal. Replace the MPM module.

Recorder Recorder Init Err Restart the equipment.

Recordhead Overheated

The recorder has been working for a prolonged time.

Clear the recording tasks and resume the recording till the recorder’s print head cools down.

Measurement Alarm Message Cause and solution Recorder

Overcurrent

Re-load the recorder paper.

Others Config Err Check if the configuration is correct, or restore the factory configuration.

Pacer Pads cable Off Check that pads cable is properly connected.

Pads Off Check that pads are properly connected.

ECG Lead Off Check that ECG leadwires are properly connected.

Pacer Stopped Abnormally

Check paddles. Check that pads well contact with patient’s skin. Make sure pads are properly applied, and then start pacing again.
