The following lists recommended actions to address problems related to
operational performance of the A3.
Condition Recommended Action
1. The monitor appears to
be operational, but the
physiological values are
suspect or nonexistent.
1. Replace each patient cable (or tubing) with a
known good cable.
2. Ensure that the Patient Connector PCB is
properly connected to the Main PCB. Ensure that
the tubing in the pneumatic system are properly
connected, and that the NiBP pump motor is
connected to the Rear Connector PCB.
3. If the problem persists, replace the Patient
Connector PCB.
4. If the problem persists, replace Main PCB.
Condition Recommended Action
1. Monitor appears to be
operational, but
physiological values are
suspect or nonexistent.
1. Replace each patient cable (or tubing) with a
known serviceable cable.
2. Ensure internal ECG, temperature, and SpO2
cables are connected to Main PCB. Ensure tubing
in pneumatic system are properly connected, and
NiBP pump motor is connected to power supply
PCB.
3. If problem persists, replace main PCB.
2. Recorder paper will not
advance.
1. Open recorder door and check paper is present.
Press recorder module firmly into monitor to
ensure recorder module is fully engaged with
connector on recorder PCB.
2. Cycle power on monitor. Recorder should execute
a line feed at conclusion of power-up sequence.
3. If problem persists, ensure main ribbon cable is
connected to printer PCB, power supply and Main
PCB.
4. If problem persists, replace recorder.
5. If problem persists, replace recorder PCB.
6. If problem persists, replace Main PCB.
