M Series Service Manual

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 T ests 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.

Preface

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

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 PowerCharger 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.

M Series Service Manual

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.
