8. Use of unspecified configuration When the equipment and/or system is used with the unspecified system configuration different than the configuration of EMC testing, it may cause increased electromagnetic emission or decreased electromagnetic immunity. Only use this equipment and/or system with the specified configuration.
9. Measurement with excessive sensitivity The equipment and/or system is designed to measure bioelectrical signals with a specified sensitivity. If the equipment and/or system is used with excessive sensitivity, artifact may appear by electromagnetic interference and this may cause mis-diagnosis. When unexpected artifact appears, inspect the surrounding electromagnetic conditions and remove this artifact source.

If the above suggested remedial actions do not solve the problem, consult your Nihon Kohden distributor or representative for additional suggestions.

For EMC compliance, refer to “Specification - Electromagnetic Compatibility” in the Reference section

The CE mark is a protected conformity mark of the European Community. The products herewith comply with the requirements of the Medical Device Directive 93/42/EEC.

Introduction

This service manual provides useful information to qualified service personnel to understand, troubleshoot, service, maintain and repair this TEC-5500 series defibrillator

The information in the operator’s manual is primarily for the user. However, it is important for service personnel to thoroughly read the operator’s manual and service manual before starting to troubleshoot, service, maintain or repair this defibrillator. This is because service personnel needs to understand the operation of the defibrillator in order to effectively use the information in the service manual.

Caution - continued

Transport

• Use the specified shipment container and packing material to transport the defibrillator. If necessary, double pack the defibrillator. Also, put the defibrillator into the shipment container after packing so that the buffer material does not get into the inside of the defibrillator.
• When transporting a board or unit of the defibrillator, be sure to use a conductive bag on. Never use an aluminum bag when transporting a board or unit on which a lithium battery is mounted. Also, never use a styrene foam or plastic bag which generates static electricity to wrap the board or unit of the defibrillator.

Handling the defibrillator

• Because the outside surface of the defibrillator is made of resin, the outside surface of the defibrillator is easily damaged. So when handling the defibrillator, remove clutter from around the defibrillator and be careful to not damage the defibrillator or get it dirty.
• Because most of the boards in the defibrillator are multilayer boards with surface mounted electrical devices (SMD), when removing and soldering the electrical devices, a special tool is required. To avoid damaging other electrical components, do not remove and solder SMD components yourself.

Measuring and Test Equipment Maintain the accuracy of the measuring and test equipment by checking and calibrating it according to the check and calibration procedures.

Service Policy, Service Parts and Patient Safety Checks

Service Policy Our technical service policy for this defibrillator is to replace the faulty unit, board

or part or damaged mechanical part with a new one. Do not perform electrical device or component level repair of the multilayer board or unit. We do not support component level repair outside the factory for the following reasons:

• Most of the boards are multilayer boards with surface mounted electrical devices, so the mounting density of the board is too high.
• A special tool or high degree of repair skill is required to repair the multilayer boards with surface mounted electrical devices.

Only disassemble the defibrillator or replace a board or unit in an environment where the defibrillator is protected against static electricity.

As background knowledge for repair, pay special attention to the following:

• You can reduce the repair time by considering the problem before starting repair.
• You can clarify the source of most of the troubles using the information from the troubleshooting tables. Refer to “Troubleshooting“ of this manual.

Refer to “Replaceable Parts List” of this manual for the service parts for technical service that we provide.

NOTE

When ordering parts or accessories from your Nihon Kohden representative, please quote the NK code number and part name which is listed in this service manual, and the name or model of the unit in which the required part is located. This will help us to promptly attend to your needs. Always use parts and accessories recommended or supplied by Nihon Kohden Corporation to assure maximum performance from your defibrillator.
