ECG Check
Note: If connected to the defib analyzer, the HV-paddles-cable (or at least one lead) must be temporarily disconnected,
because if the unit senses a connection via the paddles or HV electrodes, the 3-lead ECG signal will be ignored.
Connect the unit’s 3-lead or 5-lead ECG wire set to the ECG simulator or defib analyzer, matching
colors or designators. Turn unit’s main control dial to On. If no waveform, check that the simulator is
ON, and press the <LEAD> soft key as required. Next, check waveform “SIZE” button and set the size
such that the waveform can be easily viewed on the screen. Slightly wiggle the cable at the connectors
for a simple integrity check. See Appendix for changing the QRS volume.
5.5.
Recorder (Printer)
If necessary, place a new pad of thermal paper in the drawer with the paper coming
off the top and front of the pad facing you. Make sure the door is fully shut on both
ends. With the waveform still on display, press the <RECORDER> button and
verify the ECG printer waveform. Note the date, time and other details are within
the margin of the paper. See sample printout for reference. If necessary, clean or
replace print head. The PCMIA card, if present, automatically records data, but is
not needed for normal operation.

Joule Test – Using Dummy Load (Usually done on a weekly basis.)
Note: This very easy procedure is applicable only if the dummy load that comes with the instrument is available
.
Refer to the picture of the dummy load in the Appendix.
Turn the unit ON and plug the module into the high voltage cable (the multi-function cable = MFC). At
this instant, the instrument will automatically enter the ‘Test Mode’ once turned ON. Reduce the energy
to 30 joules, press <Charge>, and <Shock>. When successful, the Display will show “TEST OK” for a
few seconds.
5.7.
Joule Test – With Analyzer and Paddles
Zoll Specification: Energy delivered is /- 15% or 2J of setting which ever is greater
.
Note: The “Manual Mode” (not automatic) is used because this procedure is written for basic defib analyzers.
The Zoll method as published requires a
sophisticated analyzer that supplies various waveforms into the paddles.
Set the unit in Manual Mode (some units turn-on in manual, and show no soft manual-icon). If manual
mode appears unavailable, it may be necessary to perform a reset to factory defaults, also in Appendix
(see warning above). To enter manual mode with these units, hit the left-most soft key below the screen
that corresponds to ‘Manual Mode’ option displayed on the screen. Confirm the action by hitting the
right most soft key below the screen. To lessen paper waste, unlatch the printer door to temporarily
disengage. With the ECG simulator connected, press/enable “Sync On/Off”. Confirm that a blinking
heart icon flashes on the screen.
With the rotary selector on “DEFIB”, set unit for 50 joules and apply firm pressure with both paddles
onto the analyzer’s paddle plates. Press CHARGE and confirm that the tone indicating full charge
sounds within 10 seconds or less. Then press <Shock> which glows orange once the defibrillator is
charged and ready to deliver the shock. Repeat for 100 and 180 joules, whichever is larger.

Joule Test -- Automatic Mode
Testing the Automatic Mode is possible only if your defibrillator analyzer can supply the correct non-
healthy waveform(s) into the paddle connection pair. Refer to Service manual.
5.9.
Date and Time Re-Enter
Zoll M: Press and hold the right-most soft key on the unit while turning the SELECTOR SWITCH to
the MONITOR or ON position.
Zoll E: Press and hold the leftmost soft key while tuning the instrument ON using the rotary knob on the
front panel. This will lead you to ‘System Utilities’ menu.
Hit soft key corresponding to the <MORE> option at the bottom of the screen, then hit <Clock Sync>,
and then <Manual Time Set>. When the “Set Time” screen appears on the monitor the cursor will
