WARNiNG

CAUTION

Samples

1. Avoid direct contact with samples that contain bacteria or are poten-

tially infectious.

If sample material comes in contact with the analyzer surface, clean it
up immediately with a towel.

2. Ensure that the sample contains no fibrin clots, dust or other insoluble

contaminations.

If the sample contains insoluble material, false results can be pro­duced. This applies especially when fibrin clots block the sample
pipetter.

Liquid Waste

1. Potentially infectious waste must be disposed of according to the legal

regulations.

There is a risk of contamination from potentially infectious waste.

2. Contact the manufacturer of the reagent, if you require more informa-

tion about its environmental compatibility.

CAUTION

Correctness/Precision of the Measurements

To ensure that the analyzer operates correctly, controls must be measured
and the functions must be monitored.

Erroneous measurements can lead to a false diagnosis resulting in an
incorrect therapy that puts the patient at risk.

0 - 4 V 2.1 – Operator's Manual

Potential Hazards and Safety Precautions

❚ Safety Precautions During Operation

CAUTION

Correct Usage

1. The analyzer was designed for clinical-chemical analyses, electrolyte analyses,
immunological tests and medical analyses using water-soluble samples and rea­gents.

Comply with the manufacturer regulations of the reagent when using the tests on the
analyzer.

2. If reagents are used other than those developed by Boehringer Mannheim, then
Boehringer Mannheim guarantees the technical specifications of the analyzer but
takes no responsibility for the measured results.

CAUTION

Operator Qualifications

1. The operation of the analyzer should only be performed under the control of a
qualified person, who has taken part in a recognized training from Boehringer
Mannheim.

2. For clinical tests, the analyzer should only be controlled by a practitioner or a
laboratory doctor.

CAUTION

Operation and Maintenance

1. The operation and maintenance of the analyzer may only be performed according to
the described procedures. No other components other than those specified may be
touched.

2. Never open the screwed down analyzer covers when the analyzer is connected to a
power supply. Contact with the circuit boards can damage the electronic compo­nents.

V 2.1 – Operator's Manual 0 - 5

BM/Hitachi 917

3. Never touch the sample pipetter, reagent pipetter, stirrer, rinse units and all other
moving components of the analyzer when it is in operation.

If this precaution is not adhered to, damage or interruption to the analyzer can occur.

4. Never touch the reaction disk, sample disk and reagent disk when they are rotating.

If this precaution is not adhered to, damage or interruption to the analyzer can occur.

CAUTION

Environment Conditions (Installation Conditions)

Consider the specified installation conditions. If the analyzer is to be located some­where else, contact Boerhinger Mannheim customer support.

CAUTION

Limitations for Samples and Reagents

1. The reaction cells, sample cups and the tubing for liquid waste are not impervious to
organic solutions. Never use organic solutions.

2. Never use samples or reagents that can stick to the sample probe, reagent probes
or the reaction cells. This also applies to samples and reagents that may block the
sample probe or reagent probes. False measurements may be produced.

CAUTION

Loading Samples and Reagents

Only load samples and reagents into the intended positions on the analyzer. Spilt
samples and reagents can cause disruptions to the analyzer. Only load reagents when
the analyzer is in the "stand-by" mode, or when the reagent stop function permits
loading.

If this precaution is not adhered to, damage or interruption to the analyzer can occur.

0 - 6 V 2.1 – Operator's Manual

Potential Hazards and Safety Precautions

CAUTION

Analyzer Cover

The analyzer cover should always be closed during operation. Only open the cover to
load samples, etc.

CAUTION

Sample Disk

Never load new samples or change the sample disk when the LEDs, indicating that the
disk is rotating, are lit or blinking.

LED 1 indicates that sample disk 1 is rotating.

LED 2 indicates that sample disk 2 is rotating.

If this precaution is not adhered to, the analyzer can be damaged.

CAUTION

Reaction Disk

1. Never touch the reaction disk when the analyzer is operating.

2. Always follow the corresponding instructions when removing, loading or replacing
the reaction disk or the reaction cell segments.

If this precaution is not adhered to, damage or interruption to the analyzer can occur.

CAUTION

Processing of Rerun Samples

2.10 Processing of Rerun Samples

You may process rerun samples in two different ways, as automatic reruns or as manual
reruns, requested by the operator.

All tests for a sample with results that do not meet the defined criteria are placed on a
rerun list independent of the run mode.

In the START CONDITIONS global menu, two different modes are selectable - REAL TIME
and AFTER 1ST.

❚ REAL TIME: The sample is rerun without delay during the current run.
❚ AFTER 1ST: The rerun is performed at the end of the current analytical run.

The RERUN ONLY option can be used to request manually rerun samples. The instrument
highlights in the DATA REVIEW sub menu (WORKPLACE main menu) all result that are
outside the limits that are specified in the applications. These samples can be defined for
a rerun.
