Preface
This Automated Clinical Analyzer is an IVD medical equipment for indoor
use and is based on the colorimetric and turbidimetric measurement.
Its main application is expected to be colorimetric measurement, clinical
chemistry testing, immuno-serological testing, hematological testing and
urine testing in hospitals, clinical laboratories and other research
laboratories.
1. Expression of Warning and Notice
: This mark means, “Refer to accompanying documents”.

(7) Power plug
Caution
1. Do not plug or unplug with the wet hands.
It might cause electric shock.
2. Do not pull the cord when unplugging.
It might cause electric shock.
(8) Accuracy of measured data
Caution
During the operation, please check the system
condition by measuring control samples.
Inaccurate test results may lead wrong diagnosis
and improper patient treatment.
(9) Protective grounding
Caution
Use a 3-pin-plug whose ground terminal will be
connected first and be sure that the earth
resistance of terminal is less than 10 ohm.
It avoids electric shock.
(10) Warning mark
Caution
When warning or caution mark peeled off,
contact our serviceman to replace by a new one.
(11) Moving or Rejection
Caution
When not using the system for a long period, or
when moving or rejecting the system, remove
biohazards.
Wipe out the sample if the spilt sample is on the
system, with cloth dipped in 70% diluted ethyl
alcohol, in case the sample has or might have
biohazards.
