Possible Cause
Device is in AED Mode.
Pads/paddles cannot be used
for the primary ECG in
Demand Mode pacing.
If a 3-Lead cable is in use or
some wires in a 5-Lead cable
are disconnected, augmented
and V-leads may not be
selectable.
Short in the patient cable or
leads.
The multifunction electrode
pads or paddles may be
disconnected or not attached
securely.
ECG data cannot be
analyzed. An electrode may
be disconnected or the
analyzing algorithm cannot
analyze the ECG signal.
A device hardware failure
was detected.
A device hardware failure
was detected.
A device failure has been
detected. The device is
unable to deliver therapy.
Potential Solution
The Lead Select button is disabled in AED Mode. To
select a lead, exit AED Mode and enter Monitor or
Manual Defibrillation Mode.
Exit pacing or choose Fixed Mode pacing.
Confirm all leads are connected.
Run an Operational Check with the ECG cable. If the
test fails, run it without the ECG cable. If the test
passes, replace the cable. If not, remove the device from
use and call for service.
Check that the pads/paddles are properly applied. If
necessary, replace the pads.
Change the ECG in Wave Sector 1 to a lead derived
from monitoring electrodes.
Check ECG signal quality. If necessary, improve lead
position or reduce patient movement.
Disconnect the ECG cable and perform an Operational
Check. If the Leads ECG test fails, remove the device
from use and call for service. If the Leads ECG test
passes, replace the ECG cable and perform another
Operational Check.
Perform an Operational Check. If the Pads/Paddles
ECG test fails with Therapy cable, disconnect the
Therapy cable from the device when prompted in order
for the Pads/Paddles ECG Test to run without the cable
connected. If the Pads/Paddles ECG Test passes without
the cable connected, replace the Therapy cable. If the
test fails, remove the device from use and call for service.
Run an Operational Check. If it fails or the problem
occurs repeatedly, take the device out of use and call for
service.
