What to Do
Baseline offset of the ECG input signal is too large for process and display of the waveform. Replace
the Quadtrode electrode.
Note
The error message can be displayed for trace A and/or for trace B.
What to Do
The SpO2 probe is defective. Replace the SpO2 probe.
The SpO2 attachment may be improperly applied or positioned on the patient; or, the probe is
faulty.
• Check the alignment of the clip (or grip) on the patient.
• Replace the SpO2 probe.
If the message persists, contact technical support or authorized service personnel.
A hardware or other failure has occurred in the wSpO2 module. Replace the wSpO2 module.
If the failure persists, immediately remove the MR400 and the wSpO2 module from service then
contact technical support or authorized service personnel, as the system must not be used on any
patient requiring SpO2 measurement.
Interference due to attachment misalignment or incorrect attachment positioning:
• Check the alignment of the clip (or grip) on the patient site.
• Try a different limb or site.
• Ensure that the module is placed outside of the MR bore.
• Reposition the wSpO2 module (see page 6-6.
• Replace the clip (or grip).
Accuracy may be compromised due to low perfusion. The tissue at the SpO2 attachment site may
be too opaque, thick or cold.
• If the clip (or grip) is positioned on a finger, check for long, artificial or polished nails. Remove
any nail polish or relocate the attachment if needed.
• Try another attachment site, like a toe.
• Try rubbing or warming the limb to stimulate circulation.
The SpO2 probe is not attached or is improperly attached to the wSpO2 module. Check the
connection of the probe to the module. Reconnect the probe or, if the connection was good,
replace the probe.
