ii Service Manual BSM-4100

EMC RELATED CAUTION

This equipment and/or system complies with the International Standard IEC 60601-1-2 for electromagnetic

compatibility for medical electrical equipment and/or system. However, an electromagnetic environment that

exceeds the limits or levels stipulated in the 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 if it is interfered with by an emitter source such

as an authorized radio station. Keep the emitter source such as cellular phone away from the equipment

and/or system.

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.

Introduction

1. GENERAL

This service manual provides useful information to qualified personnel to

understand, troubleshoot, service, maintain and repair the BSM-4100A/J/K Bedside

Monitor (referred to as “the instrument” in this service manual).

All replaceable parts or units of this instrument are clearly listed with exploded

illustrations to help you locate the parts quickly.

The “Maintenance” section in this service manual describes the maintenance that

should be performed by qualified service personnel. The “Maintenance” section in

the operator’s manual describes the maintenance that can be performed by the user.

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

instrument. This is because service personnel need to understand the operation of

the instrument in order to effectively use the information in the service manual.

Service Manual BSM-4100 1.1

1. GENERAL

General Information on Servicing

Note the following information when servicing the instrument.

Safety

••

• There is the possibility that the outside surface of the instrument,

••

such as the operation keys, could be contaminated by contagious

germs, so disinfect and clean the instrument before servicing it.

When servicing the instrument, wear rubber gloves to protect

yourself from infection.

••

• There is the possibility that when the lithium battery is broken, a

••

solvent or toxic substance inside the lithium battery could leak out.

If the solvent or toxic substance touches your skin or gets into your

eye or mouth, immediately wash it with a lot of water and see a

physician.

CAUTION

Liquid ingress

The instrument is not drip-proof, so do not install the instrument where

water or liquid can get into or fall on the instrument. If liquid

accidentally gets into the instrument or the instrument accidentally

drops into liquid, disassemble the instrument, clean it with clean water

and dry it completely. After reassembling, use the patient safety

checks and function/performance checks to verify that there is nothing

wrong. If there is something wrong with the instrument, contact your

Nihon Kohden representative for repair.

Environmental Safeguards

Depending on the local laws in your community, it may be illegal to

dispose of the lithium battery and CRT unit in the regular waste

collection. Check with your local officials for proper disposal

procedures.

Disinfection and cleaning

To disinfect the outside surface of the instrument, wipe it with a non-

abrasive cloth moistened with any of the disinfectants listed below. Do

not use any other disinfectants or ultraviolet rays to disinfect the

instrument.

- Chlorohexidine gluconate solution: 0.5%

- Benzethonium chloride solution: 0.2%

- Glutaraldehyde solution: 2.0%

- Benzalkonium chloride: 0.2%

- Hydrochloric alkyl diaminoethylglycine: 0.5%

1.2 Service Manual BSM-4100

1. GENERAL

Transport

••

• Use the specified shipment container and packing material to

••

transport the instrument. If necessary, double pack the instrument.

Also, put the instrument into the shipment container after packing so

that the buffer material does not get inside the instrument.

••

• When transporting a board or unit of the instrument, be sure to use a

••

conductive bag. Never use an aluminum bag when transporting the

power board, power unit or board on which a lithium battery is

mounted. Also, never wrap the board or unit of the instrument with

styrene foam or a plastic bag which generates static electricity.

Handling the instrument

••

• Because the outside surface of the instrument is made of resin, it is

••

easily damaged. When handling the instrument, remove clutter from

around the instrument and be careful not to damage the instrument

or get it dirty.

••

• Because most of the boards in the instrument are multilayer boards

••

with surface mounted electrical devices (SMD), a special tool is

required when removing and soldering the electrical devices. 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 Manual BSM-4100 1.3

1. GENERAL

Service Policy, Service Parts and Patient Safety Checks

Service Policy Our technical service policy for this instrument 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 instrument or replace a board or unit in an environment where the

instrument 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 instrument. Refer to “Diagnostic Check “ of this

manual.

Service Parts

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 instrument.

1.4 Service Manual BSM-4100

1. GENERAL

Patient Safety Checks Periodic maintenance procedures and diagnostic check procedures are provided in

this manual to ensure that the instrument is operating in accordance with its design

and production specifications. To verify that the instrument is working in a safe

manner with regard to patient safety, patient safety checks should be performed on

the instrument before it is first installed, periodically after installation, and after any

repair is made on the instrument.

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

International Electrotechnical Commission’s standard, IEC60601-1 (1988):

• Protective earth resistance check

• Earth leakage current check

• Enclosure leakage current check

• Patient leakage current check

• Withstanding voltage check
