3 REMOVE TEST PLUG message
appears.
Test plug connected to
QUIK-COMBO therapy cable.
• Disconnect test plug and
connect electrodes to
QUIK-COMBO therapy cable.
Radio frequency interference
during ablation procedure.
• Monitor patient using ECG cable
and therapy cable as follows:
1 Connect ECG electrodes to
patient and ECG cable.
2 Confirm device displays
patient’s ECG waveform in
Channel 1 in Lead I, II, or III
3 Connect Therapy electrodes to
patient and Therapy cable.
4 Confirm device displays
patient’s ECG waveform in
Channel 2 in Paddles lead.
4
CONNECT CABLE or ENERGY
NOT DELIVERED
message
appears.
Therapy cable became
disconnected and energy was
removed internally.
• Reconnect cable and press
charge again.
5
ENERGY FAULT message
appears (selected and available
energy).
Defibrillator is out of calibration. • May still transfer energy.
• Contact qualified service
personnel.
6
DISARMING message appears. Discharge button not pressed
within 60 seconds after charge
complete.
• Recharge the defibrillator if
desired.
Energy selected after charge
complete.
• Recharge the defibrillator.
Therapy cable disconnects. • Reconnect electrode/cable.
7 Patient didn’t jump (no muscle
response) during defibrillator
discharge.
Patient muscle response is
variable and depends on patient
condition. Lack of visible
response to defibrillation does
not necessarily mean the
discharge did not occur.
• No action needed.
Therapy cable not connected to
therapy electrodes.
• Connect electrodes to therapy
cable.
8
ABNORMAL ENERGY DELIVERY
message appears and Shock
XJ Abnormal annotated on
printout.
Open air discharge with standard
paddles.
• Press paddles firmly on patient’s
chest when discharging.
• Perform test discharges with
defibrillation checker.
Discharge occurs with standard
paddles shorted together.
• Refer to warning, page 4-14.
Patient impedance out of range. • Increase energy and/or repeat
discharges as needed.
• Consider replacing disposable
therapy electrodes with new.
