For warranty information, refer to the AED Pro Operator’s Guide.
To maintain the warranty, strictly follow the instructions and procedures in this service manual.
Unit failure that is attributable to the use of accessories that are not manufactured by ZOLL
might void the ZOLL warranty.
Safety Considerations
Only qualified personnel should service or disassemble an AED Pro unit. Before using,
servicing, or disassembling this device, read the AED Pro Operator’s Guide. Before servicing
or disassembling any equipment, review these safety considerations and read this manual
carefully.
WARNING!The AED Pro unit can generate as much as 2500 volts with sufficient current to cause
lethal shocks.
viwww.zoll.com9650-0309-01 Rev. A
Before discharging the defibrillator, warn everyone to stand clear of the patient and equipment.
Never discharge the unit with the defibrillation pads shorted together or in open air.
Do not disassemble a battery pack or dispose of it in fire. Do not try to recharge a
nonrechargeable battery pack. If mistreated, a battery pack might explode.
This device is protected against interference from radio frequency emissions typical of the
two-way radios and cellular telephones used in emergency service or public safety activities.
You should assess the device’s performance in your typical operating environment to determine
the likelihood of radio frequency interference (RFI) from high-power sources.

Chapter 1
Maintenance Tests
This chapter describes the procedures for routine testing of the AED Pro® unit.
A test typically consists of multiple steps, each of which requires a pass/fail rating. For each
step, perform the specified action and then verify that the expected results occur. If all expected
results occur, assign a “Pass” rating to the step; otherwise, assign it a “Fail” rating.
This chapter includes the following inspection and test procedures:
• “1.0Physical Inspection” on page 1-3
• “2.0Preventive Maintenance Test” on page 1-4
• “5.0Manual Self-Test” on page 1-10
9650-0309-01 Rev. AZOLL AED Pro Service Manual1–1
CHAPTER 1MAINTENANCE TESTS
Preparations for Testing
• Gather the required equipment listed in the next section.
• Perform all the steps within each test procedure in the order specified.
If testing results indicate that the battery pack must be replaced, you will need a fully charged
spare battery pack.
Test Equipment
For some tests, you need one or more of these items:
When connected to an AED Pro unit, the simulator can send it various simulated cardiac
rhythms (ventricular fibrillation, normal sinus rhythm, or asystole) and optional simulated
chest compression readings (rate and depth), so that you can test the unit’s response.
• ZOLL Administration Software (ZAS) for Windows 2000, or XP Pro —
When installed on a personal computer that has an IrDA (wireless infrared) interface, the
ZAS application can communicate with an AED Pro unit in nonrescue mode to retrieve its
usage history, hardware and software configuration, and error log. You can also use ZAS to
view or modify the unit’s configurable settings and to retrieve event data.
• ZOLL 3-lead ECG cable (8000-0838)
For ZOLL part numbers, refer to the accessories list in the AED Pro Operator’s Guide.

1.1Is the unit clean?
1.2Are all signs of wear reasonable and not excessive?
1.3Are the front panel and housing undamaged and free of cracks?
1.4Are input connectors clean and undamaged?
1.5Are electrodes preconnected, is the cable free from damage, are the pads
sealed within the packaging, and are the electrodes within the expiration
date shown on the package?
1.6Is the battery older than 18 months? When was the last time the battery
was tested?
1.7If you are using an AED Pro 3-lead ECG cable, is it free from cuts or other
visible damage?

CHAPTER 1MAINTENANCE TESTS
2.0Preventive Maintenance Test
Use this test to verify that the AED Pro unit is working properly and ready for use.
For an alternative test using the AED Pro simulator, refer to the AED Pro Operator’s Guide.
Note:To verify that the delivered energy for the first, second, and third shocks corresponds
to the unit’s preconfigured adult energy levels, use the ZOLL Administration Software
(ZAS) to obtain the current configuration of the unit.
Tools Needed
• Fluke Impulse 4000 Defibrillator/Pacer Performance Analyzer or equivalent
• The message that reports the detected electrode type can be either ADULT PADS,
PEDIATRIC PADS, or ECG CABLE.
• Some messages are issued only if the unit is configured to do so. If an optional message is
not issued during a test, do not consider this a failure.
• In some cases a text message on the display screen is abbreviated or otherwise differs
slightly from the associated voice message.

AED Pro Error Log Messages
The AED Pro unit records internal errors in an error log, which you can retrieve by using a
Windows-based personal computer with ZOLL Administration Software (ZAS).
To retrieve the error log, follow these steps:
StepAction
1Turn off the AED Pro unit.
2Start the ZOLL Administration Software (ZAS) on the computer.
3Position the AED Pro unit so that its IrDA port has a clear line-of-sight with the computer’s
IrDA port and the ports are about 10 to 18 inches (25 to 45 cm) apart.
4Press and hold the unit’s On/Off button for at least 5 seconds to start the unit in nonrescue
mode.
5After the unit issues the message COMMUNICATIONS ESTABLISHED, refer to the ZAS
help for instructions on saving the unit’s history file and viewing the included error log.
After saving the error log file on the computer, you can use ZAS to clear the error log on the
AED Pro unit.
