RECEIVING INSTRUCTIONS
The KX-21 has been thoroughly tested before shipment, and has been packaged
carefully to prevent damage from shipping and handling. Reagents and options have
also been sent and will arrive at approximately the same time as the analyzer. Follow
these guidelines when the system arrives:
• Check to see that the arrows on the sides of the packages are pointing up. If the
arrows do not point up, remark this information on the bill of lading.
• Visually inspect the outside of the package for rips, dents, or possible shipping
damage. Document any sign of damage on the bill of lading, regardless of how
insignificant it may appear. This is for your protection!
• Notify your service representative that the KX-21 system and its components
have arrived.
• Wait for your service representative to unpack the system and open the
packages.
• Follow the unpacking and storage instructions provided on the outside of the
package. Special requirements such as refrigeration are clearly marked on the
outside of the carton and will be included in the unpacking instructions and
package inserts.

WARNING
•In the event the instrument emits abnormal odor or any smoke, turn off the power
immediately and disconnect the power plug from the wall socket.
If the instrument is used continuously in that state, there is a hazard that fire, electrical shock, or
injury may result.
Contact your Sysmex service representative for inspection.
•Take care not to spill blood or reagent, or drop wire staples or paper clips into the
instrument.
Those might cause short circuit or smoke emission. If such trouble should occur, turn off the power
supply immediately and pull off the power plug from the wall socket. Then contact Sysmex service
representative for inspection.
•Do not touch the electrical circuits inside the cover. Especially if your hands are wet,
there is a hazard that electrical shock may result.
•Always wear rubber gloves when performing maintenance work or inspection.
Use specified tools and parts.
After work is over, wash your hands with disinfectant.
There is a possibility that those areas of the hand which came in contact with blood could suffer
infection, electrical shock, or burn.
•Be careful when handling samples.
Always wear rubber gloves; otherwise infection by bacteria could result. If bacteria happen to enter
your eye or a cut, wash it off with plenty of water, and immediately see a doctor.
•When discarding waste liquid, or disassembling/assembling the related parts, do not
touch the waste liquid.
If it is contaminated with blood, infection of bacteria may result. If you should touch the waste liquid
inadvertently, wash it off with disinfectant first, then wash it off with soap.
When Handling Reagent
•If a reagent happens to enter your eye, wash it off immediately using plenty of water, and
take medical treatment at once.
•If you should swallow it inadvertently, call for a doctor immediately, drink plenty of water,
and throw up.
•If it happens to adhere to the hand or the skin of other area, wash it off using plenty of
water.
•When discarding waste liquid and instrument consumable, take proper disposing steps
as medical, ineffective, and industrial wastes.
If they are contaminated with blood, infection of bacteria may result.
•Do not modify the instrument. (Modification is prohibited by Pharmaceutical Affairs Law in
Japan.) Check the regulations that apply to laboratories in your country.

WARNING
Power Supply, Connection, and Grounding
•Never put the power plug in any socket other than the specified voltage.
Otherwise, fire or electrical shock will result.
•When installing the instrument, be sure to ground it.
Otherwise, fire or electrical shock will result.
Handling Power Supply Cord
•Take care not to damage the power cord, place a heavy device on it, or pull it forcibly.
Otherwise, the wire may break causing fire or electrical shock.
•When connecting the instrument to a peripheral (host computer), be sure to switch off the
power supply beforehand.
Otherwise, electrical shock or instrument failure may result.

INTRODUCTION
Sysmex KX-21 Operator’s Manual -- Revised October 1998 1-1
1. INTRODUCTION
The SysmexKX-21 is an automatic multi-parameter blood cell counter for in vitro
diagnostic use in clinical laboratories.
The KX-21 processes approximately 60 samples an hour and displays on the LCD screen the
particle distribution curves of WBC, RBC, and platelets, along with data of 18 parameters,
as the analysis results.
Chapter 1 introduces the overview of the instrument, analysis procedure, etc. that we
recommend you to read before using the KX-21. The main contents of Chapter 1 are as
follows:
Overview of Instrument
The important functions of the KX-21 and the options for efficient operation are explained.
Main Points of Analysis Procedure
Explanation is given on the procedure for implementing each analysis mode, descriptions and
functions of the keys on panel keyboard, and the messages on the LCD screen.
Precautions at Time of Installation
Explanation is given on the matters that need to be confirmed before installation, such as
installation space, required equipment, environmental conditions.
Instrument Specifications
The instrument specifications are described.
Menu Tree
This chapter describes the KX-21 menu tree and the corresponding chapters which explain
the usage of the menus.

INTRODUCTION
1-2 Sysmex KX-21 Operator’s Manual -- Revised October 1998
2. OVERVIEW OF INSTRUMENT
The KX-21 performs speedy and accurate analysis of 18 parameters in blood and detects the
abnormal samples. To assure easy sorting of abnormal samples in the laboratory, the
instrument displays abnormal analysis data with abnormal marks attached on the LCD
screen. Thus displayed analysis data allows detecting those samples which are outside the
tolerance and need further analysis and reconsideration.
The KX-21 employs three detector blocks and two kinds of reagents for blood analysis. The
WBC count is measured by the WBC detector block using the DC detection method. The
RBC count and platelets are taken by the RBC detector block, also using the DC detection
method. The HGB detector block measures the hemoglobin concentration using the non-
cyanide hemoglobin method.

3. OPTION UNITS
This instrument offers several option units to ensure its efficient operation. The options that
can be used with the KX-21 are:
•Serial interface: Outputs analysis data and QC data to the host computer. Ordering
Information: OUTPUT UNIT NO. 1 KX-21 (Part No. 973-4531-1)
4. OUTLINE OF OPERATION
Two analysis modes are available with the KX-21: whole blood mode and pre-diluted mode.

including analysis, settings, and data processing can be performed.
5. AUTOMATIC STOP FUNCTION OF PNEUMATIC UNIT
The KX-21, when left non-operating for 15 minutes, automatically stops the pneumatic unit.
This function saves power consumption and extends component service life. In addition,
with this function, analysis-ready status can be resumed faster than by turning on the power.
It is also possible to manually stop the pneumatic unit through the Select Menu screen.
