Multi-Function Cable Setup
• The Multi-Function cable should be plugged into the unit.
Make sure the Multi-Function cable is not plugged into its
test connector.
• Switch unit to DEFIB and set energy to 30 joules.
• The messages “CHECK PADS” and “POOR PAD
CONTACT” will be alternately displayed.
• Plug the Multi-Function Cable into its test connector.
• The message “DEFIB PAD SHORT” will be displayed.
3. Energy Delivery Test (Paddles/MFE Pads)
• Press the CHARGE button on the front panel or on the
apex paddle handle.
• Wait for the charge ready tone to sound and verify that the
energy ready value displayed on the monitor registers 30
joules (“DEFIB 30J READY”).
• If paddles are installed, using your thumbs, simultaneously
press and firmly hold the SHOCK buttons (one on each
paddle) until discharge occurs.
• If MFE cable and test connector are installed, press and
hold the SHOCK button on the front panel of the
defibrillator until discharge occurs.
• The stripchart recorder will print a short strip indicating
“TEST OK” and energy delivered if the unit delivered
energy within specifications.
• If “TEST FAILED” appears, contact appropriate technical
personnel or ZOLL Technical Service Department
immediately.
Note: During the Energy Delivery Test, unit will only
discharge when energy level is set to 30 joules.
4. Pacer Operation (Pacer Version Only)
• Turn the SELECTOR SWITCH to PACER.
• Turn PACER RATE control to 150 ppm.
• Press the RECORDER button to generate a strip.
• Verify that the pacing stimulus markers ( ) occur
approximately every 10 small divisions (2 large divisions,
1 cm).
• Press the 4:1 button and verify that the frequency of the
markers decrease (8 large divisions, 4 cm between each
marker).
• Turn the PACER OUTPUT control to 0 mA. There
should be no “CHECK PADS” or “POOR PAD
CONTACT” messages.
• Disconnect MFE Pads or paddles from the Multi-Function
cable.
• Slowly turn the knob up to 16 mA. The “CHECK PADS”
and “POOR PAD CONTACT” messages are alternately
displayed on the screen. Pace alarm sounds and flashes.
• Connect Multi-Function cable to test connector.
• Press the Clear Pace Alarm softkey. The “CHECK
PADS” and “POOR PAD CONTACT” messages disappear
and the Pace alarm stops.
5. Recorder Check
• Check for adequate supply of paper.
• Press the RECORDER button. The strip recorder will run
until the RECORDER button is pressed again.
• Press and hold the SIZE button for at least 2 seconds to
generate a calibration pulse. The calibration pulse will
remain on the display for as long as the SIZE button
remains depressed. In addition, the amplitude of the
calibration pulse is 1 mv independent of the SIZE setting.
• Inspect the recorder waveform for uniformity and
darkness.
• Inspect for uniformity of annotation characters and
completeness of words.
• Check strip recorder speed by verifying that the calibration
pulse is 2.5

½ mm wide and 10 ± 1 mm high.
