5‐14 Monitoring ECG Expression MR400 Instructions for Use
Depending upon the ECG lead cable type, attach the clips to the
Quatrode electrode contacts, as shown in the appropriate
connection diagram on page 5‐12. Squeeze each clip open then
place the clip onto the electrode contact and release.
When inserting or removing the clip leads, use the clip as the finger-
hold; never pull or apply excessive force to the wires.
If using a standard Quadtrode electrode, secure the lead cable
wires using the lead retainer.
See page 5‐3 for the location.
Check the battery indicators on the wECG module to ensure that
enough charge exists in at least one of the installed batteries:
• Green battery indicator = Charge sufficient; proceed to step 6.
• Red battery indicator = Charge low; proceed to step 5.
See page 2‐9 for details. (Also, you can reference the status
information pane; see page 2‐16.)
According to the red battery indicator(s) present on the wECG
module, insert a charged module battery into the corresponding
battery bay(s) and then recheck the battery indicator(s) to ensure a
sufficient charge before proceeding; see page 1‐24.
Check the network channel indicator on the wECG module to
ensure communication is established with the MR400:
• Steady = Good communication; proceed to step 8.
• Flashing = No communication; proceed to step 7.
See page 2‐10 for details. (Also, you can reference the status
information pane; see page 2‐16.) An inoperative ECG parameter or
wECG module is indicated by absence of an ECG waveform and a
simultaneous Lead Fail alarm.
Ensure that the wECG module is within 9.1 m (30 feet) of the
MR400, in the same MRI room or in the same shielded room, and is
set to the same wireless network channel used by the MR400; see
