Preface
The ZOLL AED 3TM defibrillator is an Automated External Defibrillator (AED) that
can be used for both adult and child victims of sudden cardiac arrest. The
defibrillator incorporates a sequence of audio and visual prompts to help
rescuers follow established AHA/ERC/ILCOR Guidelines for use of AEDs.
The ZOLL AED 3 BLS Service Manual is to be used primarily by the ZOLL®
Technical Service Department in conjunction with the ZOLL AED 3 Operator’s
Manual and the ZOLL AED 3 Administrator’s Guide. The ZOLL AED 3 defibrillator
does not require preventative maintenance due to its automatic self tests.
However, this manual provides optional maintenance tests you can perform
periodically according to local protocols.
This manual contains the following sections:
Preface—Contains safety warnings and an overview of the manual’s contents.
Review this section thoroughly before attempting to use or service the
ZOLL AED 3.
Chapter 1—Maintenance provides the recommended procedures for
evaluating the condition and performance of the ZOLL AED 3 defibrillator.
Chapter 2—Troubleshooting describes possible problems and solutions and
lists the error log messages that indicate the AED requires technical service.
Chapter 3—Functional Description provides technical descriptions of the
ZOLL AED 3 defibrillator modules.
Appendix—Hardware/System Architecture contains a diagram of the
ZOLL AED 3 hardware/system.

Checklist—Located on the back page of this manual and used to record the
results of the maintenance tests in Chapter 1.
Conventions
Throughout this document, text prompts and voice prompts are indicated by
capital italicized letters, such as CALL FOR HELP.
NOTE Notes contain important additional information on servicing the
defibrillator.
Safety Considerations
Only qualified personnel should service a ZOLL AED 3 defibrillator. Before using
this defibrillator, read the ZOLL AED 3 Operator’s Manual. Before servicing any
equipment, review these safety considerations and read this manual carefully.
Before discharging the defibrillator, warn everyone near the equipment to
STAND CLEAR.
Do not recharge, disassemble, or dispose of the battery in fire. The battery
might explode if mishandled.
WARNING! Warning statements describe conditions or actions that
can result in personal injury or death.
CAUTION Caution statements describe conditions or actions that can result
in damage to the defibrillator.
WARNING! The ZOLL AED 3 defibrillator can generate as much as
2250 volts with sufficient current to cause lethal shocks.

Chapter 1
Maintenance
The ZOLL AED 3 defibrillator automatically performs functional testing during
periodic self tests. However, this chapter provides optional maintenance tests
you can perform periodically according to local protocols. The following tests and
maintenance instructions are included in this chapter:
•Self Tests
•Cleaning
•Manual Maintenance Tests
Self Tests
The ZOLL AED 3 defibrillator performs the following self tests to verify AED
integrity and its readiness for emergency use:
•Battery Installation
•Power On
•Manual
•Automatic (Daily or Weekly, based on configuration)
•Automatic Monthly
Following successful completion of all self tests, the status indicator displays a
green check ()to show that all tests passed and that the AED is ready to use.
AED Passed
Self Test
AED Failed
Self Test

4 ZOLL AED 3 Service Manual 9650-000761-01 Rev. A
If the status indicator is blank following the completion of any self test, the
ZOLL AED 3 defibrillator is not ready for use and may be defective. Remove the
AED from service and consult the section “Chapter 2 Troubleshooting” on
page 19 to help determine the problem.
Self Test Functions
The following functions are verified during self tests. Table 1 on page 5 lists the
functions that are included in each self test.
•Battery Capacity: Verifies that the battery usage indicator shows
adequate battery capacity remaining.
•Defibrillation Pads Connection: Verifies that the defibrillation pads are
properly preconnected to the device.
•Battery Expiration Verification: Verifies that the battery is within its
install-by date.
•ECG Circuitry: Tests that the ECG signal acquisition and processing
electronics are functional.
•Defibrillator Charge and Discharge Circuitry: Verifies that the device’s
defibrillator electronics are functional and can charge and discharge at
2 joules. The following tests also include a separate 200 joule charge/
discharge test: Battery Installation Self Test, Manual Self Test, Automatic
Monthly Test.
•Microprocessor Hardware/Software: Verifies proper function of the
AED microprocessor electronics and the integrity of its software.
•CPR Circuitry and Sensor: Determines that CPR monitoring and
compression depth detection are functional (if defibrillation pads with CPR
functionality are connected).
•Audio Circuitry: Verifies that voice prompts are working.
Automatic Self-Test Transfer
All ZOLL AED 3 defibrillators come standard with Program Management
OnboardTM intelligent monitoring technology to transfer self-test data. If
configured, the AED can automatically transfer self-test information over Wi-Fi
to the ZOLL PlusTracTM AED program management system or to another AED
program management provider.

9650-000761-01 Rev. A ZOLL AED 3 Service Manual 5
Cleaning the AED
After each use, clean and disinfect the defibrillator with a soft, damp cloth using
either 90% isopropyl alcohol, or soap and water. You can also use a chlorine
bleach and water mixture (30 ml/liter water) to clean the defibrillator (except on
the contacts and connectors).
NOTE Wipe down the defibrillator with water after using any cleaning solution.
Chlorine residue that remains on the LCD screen may cause damage.
DO NOT:
• Immerse any part of the defibrillator in water.
• Use chlorine mixture on contacts or connectors; this will degrade the contacts
over time.
• Use ketones (MEK, acetone, etc.) to clean the defibrillator.
• Use abrasives (e.g., paper towel) on the display window or graphic screen.
• Sterilize the defibrillator.
