M Series Service Manual
Preface
Overview
ZOLL Medical Corporation’s M Series Service Manual is intended for the service technician whose responsibility
is to identify malfunctions and/or make repairs at the subassembly level. The Zoll M Series Service Manual has five
main sections and one appendix.
Preface—Contains safety warnings and an overview of the manual’s contents. Be sure to review this section
thoroughly before attempting to use or service the M Series unit.
Chapter 1—Maintenance Tests explains how to check the defibrillator’s performance using a series of recommended
checkout procedures to be conducted every six months.
Chapter 2—Troubleshooting provides a listing of the procedures and error messages to help the service technician
detect faults and repair them.
Chapter 3—Disassembly Procedures describes step-by-step procedures for removing subassemblies from the
M Series unit.
Chapter 4—Replacement Parts List displays a complete list of ZOLL part numbers for field replaceable parts
available for the M Series unit, allowing the service person to identify and order replacement parts from ZOLL.
Chapter 5—Functional Description provides technical descriptions for the M Series major subassembly modules.
Appendix A—M Series Operator’s Manual.
Safety Considerations
The following section describes general warnings and safety considerations for operators and patients. Service
technicians should review the safety considerations prior to servicing any equipment and read the manual carefully
before attempting to disassemble the unit. Only qualified personnel should service the M Series unit.
Federal (U.S.A.) law restricts this unit for use by or on the order of a physician.
Safety and effectiveness data submitted by ZOLL Medical Corporation to the Food and Drug Administration (FDA)
under section 510(K) of the Medical Device Act to obtain approval to market is based upon the use of ZOLL
accessories such as disposable electrodes, patient cables and batteries. The use of external pacing/defibrillation
v
Page 8
M Series Service Manual
electrodes and adapter units from sources other than ZOLL is not recommended. ZOLL makes no representations or
warranties regarding the performance or effectiveness of its products when used in conjunction with pacing/
defibrillation electrodes and adapter units from other sources. If unit failure is attributable to pacing/defibrillation
electrodes or adapter units not manufactured by ZOLL, this may void ZOLL's warranty.
Only qualified personnel should disassemble the M Series unit.
WARNING!
This unit can generate up to 4500 volts with sufficient current to cause lethal shocks.
All persons near the equipment must be warned to “STAND CLEAR” prior to discharging the defibrillator.
Do not discharge the unit’s internal energy more than three times in one minute or damage to the unit may result.
Do not discharge a battery pack except in a Base PowerCharger4x4 or compatible ZOLL Battery Charging/Testing unit.
Do not use the M Series in the presence of flammable agents (such as gasoline), oxygen-rich atmospheres, or
flammable anesthetics. Using the unit near the site of a gasoline spill may cause an explosion.
Do not use the unit near or within puddles of water.
NOTE
The M Series is protected against interference from radio frequency emissions typical of two-way radios and cellular
phones (digital and analog) used in emergency service/public safety activities. Users of the M Series should assess the
unit’s performance in their typical environment of use for the possibility of radio frequency interference from
high-power sources. Radio Frequency Interference (RFI) may be observed as shifts in monitor baseline, trace
compression, or transient spikes on the display.
Additional Reference Material
In addition to this guide, there are several other components to the Zoll M Series documentation. They include:
• Operator’s Guide - A comprehensive reference work that describes all the user tasks needed to operate the M Series.
• Configuration Guide - Describes the M Series features and functions whose operation can be customized by
authorized users.

Chapter 1
Maintenance Tests
Overview
The M Series has two checkout procedures: the operator’s shift checklist and the extensive six-month maintenance
tests checkout procedures.
Because the M Series units must be maintained ready for immediate use, it is important for users to conduct the
Operator’s Shift Checklist procedure at the beginning of every shift. This procedure can be completed in a few minutes
and requires no additional test equipment. (See the ZOLL M Series Operator’s Guide for the Operator’s Shift
Checklist.)
A qualified biomedical technician must perform a more thorough maintenance test checkout every six months to
ensure that the functions of the M Series unit work properly. This chapter describes the step by step procedures for
performing the six month maintenance test checkout. Use the checklist at the back of this document (ZOLL M Series
Maintenance Tests Checklist) to record your results of the maintenance tests.
This chapter describes the following M Series maintenance tests:
1. Physical Inspection of the Unit
2. Front Panel Button
3. 3, 5, and 12 Leads
4. Power Supply
5. Leakage Current
6. Paddles
7. Heart Rate Display
8. Calibrating Pulses on Strip Chart
9. Notch Filter
10. Heart Rate Alarm

Tests” section shown below.
• Keep an extra fully charged ZOLL M Series compatible battery available.
• Schedule an hour to conduct the entire maintenance test.
• Photocopy the checklist at the back of this document and use the copy to record your results. As you conduct each
step of a procedure, mark the
Pass/Fail/NA check boxes on your checklist and then save it for your maintenance file.
• Perform the tests in the order presented.
• Perform all the steps of each test procedure.
• Complete all the steps of the procedure before evaluating the test results.

Equipment that You Need to Perform the M Series Maintenance
Tests
This section lists equipment that we use to perform the maintenance tests that we describe in this chapter. You can
substitute an equivalent device for a listed device; however, not all simulators and analyzers will produce the same
results. Be sure to follow the manufacturer’s recommendations for conducting the maintenance tests.
We recommend the use of the following equipment when performing M Series Maintenance Tests:
• ZOLL Medical Electrode Adapter from Fluke Biomedical (ZOLL Part Number 3010-0378).
• QED 6 Defibrillator Analyzer
• MFC Test Port Connector, 1004-0053-99
• Fluke Biomedical 601 Pro Series International Safety Analyzer.
• ECG Simulator; 12 Lead Simulator for 12 Lead test (e.g., Symbio CS1201).
• Stop watch.
• Standard series II PC flash memory cards.
• 1 red miniature alligator to miniature alligator test lead.
• 1 black miniature alligator to miniature alligator test lead.
• DC power supply (15 amp minimum).
• 0.1 ohm 1% resistor (1/4 watt or greater).
• 1000 ohm 1% resistor (1/4 watt or greater).
• Fluke 75 Multimeter or equivalent.
• Printer Paper.
• Battery.
• AC line cord.
• 3 lead, 5 lead and 12 lead ECG cables. (12 lead cable needed if 12 lead option is installed.

Page 14
M Series Service Manual
Equipment You Need for the M Series Options Maintenance
Tests
• Fluke Biomedical Index 2 SpO2 Simulator or equivalent. (For SpO2 units only.)
• SpO2 cable and sensor (if option is installed).
• EtCO2 cable, and CAPNOSTAT 3 Mainstream cable with airway adapter, or CAPNOSTAT 3 Sidestream cable with
cannula (if option is installed).
• Novametrix Capnostat Simulator Yb 1265/7100
• Paddles (if used).
• )
• Fluke Biomedical BP Pump 2 NIBP Monitor Analyzer (For NIBP units only) with NIBP cable and cuff (if NIBP
option is installed), or
• Fluke Biomedical Cufflink Analyzer (if NIBP option is installed)
• IBP Temperature Simulator 9100-0402-TF
• DNI Nevada 214B Patient SImulator, with M Series interface cable
NOTE The Fluke Biomedical BP Pump NIBP Monitor Analyzer and the Fluke Biomedical BP Pump NIBP Analyzer
use different technologies for testing NIBP monitors and therefore, the manual provides two different procedures for
performing the NIBP Volume Leak test with each of these types of test equipment.
