If a leadwire is disconnected, the overall status shows as failed (red). To determine
which leadwire has failed, you need to understand which electrodes are used to
form a lead. If RA is the reference electrode and it is not connected, all the electrodes
display as failed. If another leadwire is the reference electrode and it is not connected,
only that electrode displays as failed.
CAUTION:
ELECTRICAL INTERFERENCE - Electrostatic discharges may interfere with the
acquisition of ECG recordings. The acquisition module could be temporarily
disconnected with an error message displayed due to an ESD event. The device
recovers automatically from this error. ECG recordings need to be restarted after
the error message is removed and the acquisition module recovers.
