TD 4255

Dear

GLUCOCHECK CLASSIC

system owner:
This manual contains important information you must know
about the system. Please read it thoroughly and carefully.

GlucoCheck Classic uses “No Coding Needed” technology.
What this means is fewer steps during the testing process,
and no risk of false readings because of errors related to
incorrect coding. This ensures a more accurate result.

GlucoCheck system also has a top-loading strip port with
strip ejection capability, ensuring optimal safety for health­care providers and convenience. The strip eject function
eliminates any blood contamination dangers associated
with manually releasing a strip, offering the safest disposal
possible.

The GlucoCheck Classic System stores 450 readings with
time and date. This helps you to manage your diabetes
more effectively.

If you have any questions please contact the GlucoCheck
Care line on 0861106 150.

IMPORTANT INFORMATION

Severe dehydration and excessive water loss may

cause false results. If you believe you are suffering
from severe dehydration, consult a healthcare profes­sional immediately.

If you get your blood glucose results lower or higher

test. If you have symptoms or continue to get results
higher or lower than usual, follow the treatment advice
of your healthcare professional.

Apply only capillary whole blood sample to test your

blood glucose. Applying other substances will cause
wrong results.

If you are experiencing symptoms that are not consis-

tent with your blood glucose test results and you have
followed all instructions described in this owner’s man-
ual, call your healthcare professional.

Inaccurate results may occur in severely hypotensive

individuals or patients in shock. Inaccurate low re­sults may occur for individuals experiencing a hyper­glycemic-hyperosmolar state, with or without ketosis.

Critically ill patients should not be tested with blood
glucose meters.

Please refer to your test strip package insert for

additional important information.

ABOUT ALTERNATIVE SITE TESTING (AST)

Important: There’re limitations for doing AST.
Please consult your healthcare professional before
you do AST.

What is AST?

Alternate site testing (AST) means that people use parts

palm, the forearm, the upper arm, the calf, and the thigh

What’s the advantage?

Fingertips feel pain more readily be­cause they are full of nerve endings
(receptors). At other body sites, since
nerve endings weren’t so condensed,
you won’t feel as much pain as at the

the last meal).

GETTING STARTED

Intended Use

The system is intended for use outside the body (

in vitro

diagnostic use). It should be used only for testing glucose
(sugar) and only with fresh capillary whole blood samples

calf and the thigh). The system is intended for use in the
home and in clinical settings. It should not be used for the
diagnosis of diabetes or for the testing of newborns.

AST in this system can be used only during steady-state
blood glucose conditions described in the section of “About
AST”.

Principle of Measurement

The test is based on the measurement of electrical current
generated by the reaction of glucose with the reagent of
the strip. The meter measures the current and displays the
corresponding blood glucose level. The strength of the cur­rent produced by the reaction depends on the amount of
glucose in the blood sample.

Contents of the System

These products included in the kit have been designed,
tested, and proven to work together as a system to pro­duce accurate blood glucose test results. Use only the
same brand-name test strips and a control solution with
the blood glucose meter.

Appearance of the Test Strip

This system measures the amount of sugar (glucose) in
whole blood. Blood is applied to the absorbent hole of the
test strip and is automatically drawn into the reaction cell
where the reaction takes place.

The test strip consists of the following parts:

Contact Bars

Insert this end of the test strip into the meter.

PREPARATION BEFORE USE

Battery Replacement

Your meter comes with two 1.5V AAA alkaline batteries.
The meter will alert you when the power is getting low by
displaying two different messages:

1. When symbol appears

on the display: the meter is
functional and the result re­mains accurate, but it is time
to change the battery.

2. With symbol, low and

E-b symbols on the displays:
the battery can not provide
enough power for a test. You
must change the battery
immediately.

PLEASE NOTE!

Batteries might leak chemicals if not used for a long time. Remove
the battery if you are not going to use the device for an extended
period (i.e., 3 months or more).
Do not use the used battery. Use only the new one in required
size and type.

14

To replace the battery, make sure that the meter is
turned off.

STEP1

Press the buckle on battery cover and lift up to

remove the cover.

STEP2

Remove the old battery and replace with two 1.5V

AAA alkaline batteries.

STEP3

WARNING

As with all small batteries, the batteries should be kept away from small
children who still put things in their mouths. If they are swallowed,
promptly see a doctor for help.

PLEASE NOTE!

The time and date can ONLY be changed in the setting mode.
Therefore, when you perform a glucose testing, those parameters
are not possible to be changed.
The meter cannot automatically update daylight saving time. You
have to manually adjust the time in the meter according to the
procedures. Please make sure the meter matches the time zone
and adjust the daylight saving time data if required.
Your meter displays 7-, 14-, 21-, 28-, 60- and 90-day averages
which you can access from the meter memory. These averages
are calculated from results obtained during the 7-, 14-, 21-, 28-,
60- and 90-day preceding the current date and time settings.
When the date and time are changed, the 7-, 14-, 21-, 28-, 60­and 90-day averages may change.
While the meter is in the setting mode, it will turn off automatically
without any action in three minutes.
