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 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.
