1Introduction
This Service Manual provides the information needed to successfully service
the Philips M3500B HeartStart XLT and the Laerdal M5500B Heartstart 4000
Defibrillator/Monitors. The intended users of this manual are technical per-
sonnel who have been trained in the safe and proper servicing of the M3500B/
M5500B.
Overview
In this chapter, you’ll find general information that you should become famil-
iar with before servicing the M3500B/M5500B. Detailed information regard-
ing controls, operation, and capabilities of the instrument can be found in the
Instructions for Use that was shipped with the product. We recommend you
review the Instructions for Use before servicing this device. This Service
Manual assumes you are familiar with the controls and with basic operations.
Defibrillator/Monitor
The M3500B/M5500B is a biphasic, semi-automatic external defibrillator.
This portable, lightweight device offers two modes of operation for defibrilla-
tion:
zSemi-Automatic External Defibrillation (AED) Mode
zManual Mode
In AED Mode, the M3500B/M5500B analyzes the patient’s ECG and advises
the clinician whether or not to deliver a shock. In Manual Mode, the M3500B/
M5500B turns control of the defibrillation process over to the clinician. The
clinician analyzes the patient’s ECG, decides if defibrillation is advised, and
determines the energy setting for defibrillation. Manual Mode also allows the
clinician to perform synchronized cardioversion and offers optional noninva-
sive pacing (using a monophasic waveform).
Defibrillation is performed through multifunction defib electrode pads. In
addition, both AED and Manual Mode offer monitoring through pads, 3-lead
ECG monitoring electrodes, or optional 5-lead ECG monitoring electrodes.
Optional pulse oximetry (SpO2) monitoring is available in both modes, as
well.

Overview
1-2Introduction
The M3500B/M5500B automatically stores critical events, such as shocks
and alarm violations, in its internal memory. An Event Summary may be
printed at any time. The M3500B/M5500B also enables you to store data and
events on an M3510A/M5510A Data Card for downloading to the Event
Review Data Management System.
Batteries, Power Modules, Battery Charger Adapter
The M3500B/M5500B is powered by a rechargeable Sealed Lead Acid (SLA)
battery (M3516A/M5516A). Proper care of these batteries will ensure that
they have the energy required to operate the M3500B/M5500B and deliver the
appropriate therapy (See "Battery Maintenance" section in Instructions for
Use).
Batteries may be charged either in the defibrillator or in the Battery Charger
Adapter (M3506A/M5506A). In either case, power for charging can be pro-
vided by the AC Power Module (M3517A/M5517A), or by the DC Power
Module (M3518A/M5518A).
NOTE The defibrillator will take longer to charge when powered with either power
module without a battery installed. The recommended practice is to use a bat-
tery in conjunction with the power module to ensure optimal performance.
For information on either the power modules or the adapter, see the documen-
tation supplied with the power module or adapter.
Installation
The M3500B/M5500B does not require installation. The Instructions for Use
describes the setup required before placing the device into service, as well as
configuration options.
Upgrades
Upgrades are available to add specific functionality to units in the field. As of
the publication of this manual, these upgrades are:
zM3514A Pacing Upgrade (adds pacing)
zM3515A SpO2 upgrade.
Consult your sales representative or dealer or distributor for the latest details.
Preventive Maintenance
Preventive maintenance and periodic operational checks are intended to be
performed by the user. Both topics are covered in the Maintenance chapter of
the Instructions for Use.

Overview

Repair Philosophy
Defibrillator/Monitor
The repair philosophy of the M3500B/M5500B is subassembly replacement.
Examples of subassemblies are the printer, the Control Printed Circuit Assem-
bly (PCA), and selected connectors and other items. Repairs that involve
replacing components on a PCA are not supported.
CAUTION Individual component replacement should not be attempted outside of a fac-
tory authorized repair facility. Component level repair is extremely difficult
due to the extensive use of surface mount technology and the high parts-den-
sity on the circuit boards. Unauthorized component replacement can impair
performance of the M3500B/M5500B.
Batteries, Power Modules, Battery Charger Adapter
The repair philosophy for the SLA battery (M3516A/M5516A), AC Power
Module (M3517A/M5517A), DC Power Module (M3518A/M5518A), and
the Battery Charger Adapter (M3506A/M5506A) is unit replacement. These
accessories are not repaired in the field.
For information on ordering replacements, see "Supplies & Accessories" on
page 5-16.
