Restoring Default Settings
Using the Module Configuration Manager feature, you can restore all default
settings. User-configurable settings are described in Setting User-Defined Default
Values on page 7-7.
After the default settings are restored, the system initiates a learn sequence.
Following the learn sequence, rate and ST alarm limits are reset.
Power Failure
In the case of a power failure, the remote module housing (90499) provides +5V
of power to maintain data integrity. If the power is interrupted to the remote
module housing but not to the monitor, the following will occur:
• all parameters will display ??? in the numeric zone
• ECG will display Channel 1 & 2 Leads Off
• Respiration will display Loss of Signal
• Cardiac output will display Catheter Fault and Probe Fail
•SpO
2
will display Adapter Disconnected
ECG Problem Solving
In general, if ECG signal quality is poor (as evidenced by wandering baseline,
excessive noise, or muscle or respiration artifact), try the following solutions:
• Ensure that the patient's skin was properly prepared.
• Ensure that all electrodes are firmly attached and in good condition.
• Ensure that the electrodes are positioned on a flat, non-muscular area.
• Ensure that lead wires are properly fastened and in good condition.
If this fails to resolve the problem, select a different lead.
By following the instructions provided in this chapter and discussed during
inservice education, you can avoid most common monitoring problems. If a
problem occurs, consult the ECG Troubleshooting Guide on page 8-21. The
following additional information should help you resolve a few of the more
complex problems.
Lead Fault Indication
If a lead fault occurs, the message CHECK XX is displayed in the ECG waveform
zone, where XX identifies the failed or missing electrode. If automatic lead
switching is enabled, the module selects another lead automatically so that
monitoring is uninterrupted. If automatic lead switching is disabled, a LEAD OFF
message is displayed.
