Troubleshooting
Leads Off
message even though
ECG cable has been replaced and
is properly connected to the simula-
tor.
Open in internal Leads ECG wiring
or front end, due to:
Cable from ECG Connector to Inter-
face PCA has bad connection.
Reconnect cable properly. See "Ser-
vicing Notes" on page 4-1.
Defective ECG Connector or cable
to Interface PCA.
Replace ECG Connector.
Defective Interface PCA
Replace Interface PCA.
Pads Off
message even though
pads cable has been replaced and
is properly connected to the simula-
tor.
Open in internal Pads ECG wiring or
front end, due to:
Cable from Patient Connector to
Power PCA has bad connection.
Reconnect cable properly. See "Ser-
vicing Notes" on page 4-1.
Defective Patient Connector or
cable to Power PCA.
Replace Patient Con its
internal cable.
Defective Power PCA.
Replace Power PCA.
Trace distorted.
Failure in ECG front end.
Pads: Replace Power PCA.
Leads: Replace Interface PCA.
Failure in signal processing circuits.
Replace Control PCA.
One or more ECG controls don’t
respond (e.g., select lead or ECG
size).
Failure in keypress detection/pro-
cessing.
1. Replace Control PCA.
2. Replace Interface PCA.
Failure in keys/connections.
Replace Top Case Assembly.
Poor Leads ECG signal quality.
The monitoring electrodes are not
making proper contact with the
patient.
Check that the monitoring elec-
trodes are properly applied. If nec-
essary, prepare the patient’s skin
and apply new electrodes.
The monitoring electrodes are out-
dated or dried-out.
Check the date code on the elec-
trodes. Do not open the electrode
package until immediately prior to
use.
Radio frequency interference (RFI)
is causing artifact.
Relocate or turn off equipment that
may be causing RFI.
