Safety Considerations
Only qualified personnel should service or disassemble an AED Plus unit. Before using this
device, read the AED Plus Administrator’s Guide. Before servicing or disassembling any
equipment, review these safety considerations and read this manual carefully.
WARNING! The AED Plus unit can generate as much as 2250 volts with sufficient current to cause
lethal shocks.
Before discharging the defibrillator, warn everyone near the equipment to “STAND CLEAR.”
Use only Type 123A lithium manganese dioxide batteries from manufacturers recommended
by ZOLL. Discard used batteries properly.
Do not recharge, disassemble, or dispose of batteries in fire. Batteries might explode if
mistreated.
This device is protected against interference from radio frequency emissions typical of the
two-way radios and cellular telephones used in emergency service and 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.
Warranty
For warranty information, refer to the AED Plus Administrator’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

Chapter 1
Maintenance Tests
This chapter describes the procedures for routine testing of the AED Plus 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:
•“1.0 Physical Inspection” on page 1-3
•“2.0 Preventive Maintenance Test” on page 1-4
•“3.0 Manual Self-Test” on page 1-9

CHAPTER 1MAINTENANCE TESTS
1–2 www.zoll.com 9650-0308-01 Rev. A
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 batteries must be replaced, you will need a set of 10 fully
charged Type 123A batteries.
Test Equipment
For some tests, you need one or more of these items:
•ZOLL universal adapter cable
•Fluke®Impulse 4000 Defibrillator/Pacer Performance Analyzer (Fluke Biomedical/
DNI Nevada) with 1.06 software or higher
The following items are optional:
•ZOLL AED Plus Simulator —
When connected to an AED Plus 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) —
When installed on a personal computer or personal digital assistant that has an IrDA®
(wireless infrared) interface, the ZAS application can communicate with an AED Plus 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.
For ZOLL part numbers, refer to the accessories list in the AED Plus Administrator’s Guide.

2.0 Preventive Maintenance Test
Use this test to verify that the AED Plus unit is working properly and ready for use.
For an alternative test using the AED Plus Simulator, refer to the AED Plus Administrator’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
•Universal adapter cable
Test Setup
•Turn off the AED Plus unit, remove the cover, and unplug the preconnected electrodes.
Keep the electrodes so they can be reconnected later.
•Connect the universal adapter cable to the AED Plus unit and to the analyzer.
•Turn on the analyzer and set its function to VF (ventricular fibrillation).
Variations in Messages
When verifying messages in the test results, please be aware of the following issues:
•The wording of some messages is configurable. The following table shows equivalent
messages.
•The message that reports the detected electrode type can be either ADULT PADS or
PEDIATRIC PADS.
•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.
