EMC RELATED CAUTION

This equipment and/or system complies with IEC 60601-1-2 International Standard for electromagnetic compatibility for medical electrical equipment and/or system. However, an electromagnetic environment that exceeds the limits or levels stipulated in IEC 60601-1-2, can cause harmful interference to the equipment and/or system or cause the equipment and/or system to fail to perform its intended function or degrade its intended performance. Therefore, during the operation of the equipment and/or system, if there is any undesired deviation from its intended operational performance, you must avoid, identify and resolve the adverse electromagnetic effect before continuing to use the equipment and/or system.

The following describes some common interference sources and remedial actions:

1.Strong electromagnetic interference from a nearby emitter source such as an authorized radio station or cellular phone:

Install the equipment and/or system at another location. Keep the emitter source such as cellular phone away from the equipment and/or system, or turn off the cellular phone.

2.Radio-frequency interference from other equipment through the AC power supply of the equipment and/or system:

Identify the cause of this interference and if possible remove this interference source. If this is not possible, use a different power supply.

3.Effect of direct or indirect electrostatic discharge:

Make sure all users and patients in contact with the equipment and/or system are free from direct or indirect electrostatic energy before using it. A humid room can help lessen this problem.

4.Electromagnetic interference with any radio wave receiver such as radio or television:

If the equipment and/or system interferes with any radio wave receiver, locate the equipment and/or system as far as possible from the radio wave receiver.

5.Interference of lightning:

When lightning occurs near the location where the equipment and/or system is installed, it may induce an excessive voltage in the equipment and/or system.

WARNING

Interaction Between Minute Ventilation Rate-Adaptive Pacemakers and Cardiac Monitoring and Diagnostic Equipment*

The bioelectric impedance measurement sensor of a minute ventilation rate-adaptive implantable pacemaker may be affected by cardiac monitoring and diagnostic equipment which is connected to the same patient. If this occurs, the pacemaker may pace at its maximum rate and give incorrect data to the monitor or diagnostic equipment. If this occurs, disconnect the monitor or diagnostic equipment from the patient or change the setting on the pacemaker by referring to the pacemaker’s manual. For more details, contact your pacemaker representative or Nihon Kohden representative.

*Minute ventilation is sensed in rate-adaptive pacemakers by a technology known as bioelectric impedance measurement (BIM). Many medical devices in addition to pacemakers use this technology. When one of these devices is used on a patient with an active, minute ventilation rate-adaptive pacemaker, the pacemaker may erroneously interpret the mixture of BIM signals created in the patient, resulting in an elevated pacing rate.

For more information, see the FDA web site. http://www.fda.gov/cdrh/safety.html

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

1.6	Service Manual BSM-6000

Service Policy and Patient Safety Checks

1. GENERAL

1

Service Policy

Our technical service policy for the monitor 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 and special repair skill is required to repair the multilayer boards with surface mounted electrical devices.

Disassemble the monitor or replace a board or unit in an environment where the monitor 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 diagnostic check function of the monitor.

Patient Safety Checks

Periodic maintenance procedures and diagnostic check procedures are provided in this manual to ensure that the monitor is operating in accordance with its design and production specifications. To verify that the monitor is working in a safe manner with regard to patient safety, patient safety checks should be

performed on the monitor before it is first installed, periodically after installation, and after any repair is made on the monitor.

For patient safety checks, perform the following checks as described in the

International Electrotechnical Commission’s standard, IEC 60601-1: 1988.

•Protective earth resistance check

•Earth leakage current check

•Enclosure leakage current check

•Patient leakage current check

•Withstanding voltage check
