General Service Information 1: Introduction

Preventive Maintenance
Preventive maintenance and periodic operational checks are intended to be performed by the user. These
topics are respectively covered in the “Maintenance” and “Operational and Shift Checks” chapters of the
Instructions for Use.
The Maintenance chapter of this manual provides Battery and NBP calibration and testing procedures.
Experienced and trained HeartStart XL+ users (e.g. nurses or biomedical and clinical engineers) may
perform the NBP calibration using the NBP calibration kit (453564063841). The training material is
included in the kit.
CAUTION: Only qualified service personnel should perform the NBP testing procedures.
Repair Philosophy
Defibrillator/Monitor
The repair philosophy of the HeartStart XL+ is subassembly replacement. Examples of subassemblies are
the printer, the Processor Printed Circuit Assembly (PCA), Therapy 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. Component level repair is inadvisable due
to the extensive use of surface mount technology and the high parts-density on the circuit boards.
Unauthorized component replacement can impair performance of the HeartStart XL+ and void
warranty.
WARNING: Remove all power sources (AC and battery) before opening the device. Failure to do so may allow the
device to charge without warning and could result in serious injury or death.
Batteries
The 989803167281 lithium-ion battery is rechargeable. The battery periodically requires calibration. At
the end of the battery’s useful life, it should be recycled or discarded according to local regulations and
replaced. Refer to the HeartStart XL+ Instructions for Use for additional information.
For information on ordering replacements, see “Ordering Supplies and Accessories” on page 175.
WARNING: Never crush, penetrate, or attempt to open lithium-ion batteries. Never incinerate lithium-ion batteries.
High case temperatures resulting from abuse of the battery could cause physical injury. The electrolyte is
highly flammable. Rupture of the battery pack may cause venting and flame.
CAUTION: Due to their high energy density, lithium-ion batteries can deliver significant power. Use care when
working with or testing lithium-ion batteries. Do not short-circuit the terminals.
