EMC RELATED CAUTION
This equipment and/or system complies with the International Standard IEC60601-1-2 for electromagnetic
compatibility for medical electrical equipment and/or system. However, an electromagnetic environment
that exceeds the limits or levels stipulated in the IEC60601-1-2, 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.
If the above suggested remedial actions do not solve the problem, consult your Nihon Kohden Corporation
subsidiary or distributor for additional suggestions.
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.
The CE mark only applies to the BSS-9800K Bedside Station.
This equipment complies with International Standard IEC60601-1-2 (1993) which requires CISPR11, class A.
Class A EQUIPMENT is allowed in domestic establishments when used under the jurisdiction of a health
care professional.
Service Manual BSS-9800 i
Page 11
In IEC 60601-1-2 Medical Electronic Equipment, Part 1: General Requirements for Safety, 2. Collateral
Standard: Electromagnetic compatibility-Requirements and test. Section 36. 202. 2 Radiated radio-
frequency electromagnetic fields, PATIENT COUPLED EQUIPMENT and/or SYSTEMS applicable IMMUNITY
test methods are under consideration at SC62A/WG13. The 3 V/m IMMUNITY level may be inappropriate
especially when measuring SpO2 because physiological signals can be much smaller than those induced
by a 3 V/m electromagnetic field.
When measuring SpO2, various interference may produce false waveforms which look like pulse
waveforms. SpO2 value and pulse rate may be measured from these false waveforms, causing the alarm to
function improperly.
When installing the monitor, avoid locations where the monitor may receive strong electromagnetic
interference such as radio or TV stations, cellular phone or mobile two-way radios.
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 distributor or Nihon Kohden distributor.
* 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.

Introduction
1. GENERAL
This service manual provides useful information to qualified personnel to
understand, troubleshoot, service, maintain and repair the BSS-9800A/J/K Bedside
Station (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 BSS-9800 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. 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 BSS-9800 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. 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

Using the Output Signal from the ECG/BP OUT Socket
WARNING
When using the output signal from the module as the synchronization
signal for other equipment such as IABP (intra-aortic balloon pump) or
defibrillator:
••
• Set the timing of the other equipment by checking the waveform on
••
the monitoring screen.
••
• Check the condition of the bedside monitor at all times. The output
••
signal may become unstable.
••
• The hum filter is always set to on for the ECG output. ECG output
••
differs from the ECG on the monitor screen regardless of the filter
setting.
••
• Check that the delay time of the output signal (heart rate trigger 100
••
ms maximum) is within the range of the connected equipment. Refer
to Part II, Section 5.
••
• Do not use the heart rate trigger as the synchronization signal for a
••
defibrillator.
NOTE
The output signal from the ECG/BP OUT socket may become unstable
in the following conditions.
••
• Electrode is dry or detached.
••
••
• Electrode lead is damaged or disconnected from the electrode.
••
••
• Electrode lead is pulled.
••
••
• AC interference or EMG noise superimposed.
••
••
• Air bubbles or blood clog in the circuit for monitoring IBP.
••
••
• Any cord or cable disconnected or damaged.
••
Using MULTI Sockets for CO and CO2 Monitoring
WARNING
••
• When performing defibrillation during CO monitoring, never touch
••
the CO connection cord. Otherwise the discharged energy may
cause serious electrical burn, shock or other injury.
••
• When performing defibrillation during CO2 monitoring with the TG-
••

3. DIAGNOSTIC CHECK
Wave Display 1 and 2 Check
NOTE
Wave Display 2 check cannot be performed on the VL-900PA color LCD
unit because the display unit does not support the XGA mode.
This item checks the blocks for creating the waveform screen. The difference
between Wave Display 1 and 2 checks is the display resolution. The resolution is
640 × 480 dots (VGA mode) at the Wave Display 1 and 1,024 × 768 dots (XGA
mode) at the Wave Display 2.
When this check is performed on the color display unit (VD-900RA/K), the
background of the screen outside the check window is black due to screen
resolution difference between the color display unit (VD-900RA/K) and color LCD
unit (VL-900PA).

When this item is selected, the check automatically starts and 12 rectangular
waveforms are displayed on the screen. The outline of each rectangular waveform
is in white and the bold lines in red and blue are superimposed on the vertical line
of the rectangular waveforms as shown above.
In this check, verify the following:
• Each rectangular waveform is correctly displayed without blur or distortion.
• Each rectangular waveform is correctly colored as shown above.
If the rectangular waveforms are not displayed correctly, the display unit may be
faulty.
