1.2 Main features
Fast testing
The meter needs only approximately 5 seconds for each test.
Simple blood dosing
Blood is drawn up into the strip through capillary action. This makes it
easy to dose and test blood from alternative sites such as the base of
the thumb or forearm.
Blood volume checking
Testing starts automatically when the meter detects that you have
applied sufficient blood (approximately 1.5 µL (1 µL (microlitre) = one
thousandth of a millilitre)). If testing does not start, you may apply more
blood.
Particularly hygienic
Thanks to the type of test strip used, there is no direct contact between
the meter and blood. The test strip ejector also means that there is no
direct contact with blood on the used test strip.
Easy to operate
No need to press buttons when you carry out the test. The test strip
turns the meter on and off. The results are saved automatically.

Two ways to change settings
You can change settings such as the time in two different ways: using
Standard set-up or Quick set-up. Standard set-up takes you step by
step through all the available settings. Quick set-up allows you to go
directly to the setting you wish to change.
Alarm clock function
You can set up to four separate times at which you would like the meter
to remind you to test your blood glucose.
Target range for results
You can define a target range for your results. The meter beeps and
indicates in the display if a test result is outside this range.
Downloading data to a computer
The meter has an infrared port enabling you to download results to a
computer running the appropriate software.
Integrated data analysis
From the results stored in memory your meter can average your blood
glucose results for the last 7, 14 or 30 days.

14 Introduction
Farbe: P 021 – Prüfmittelnummer: 201
Acoustic Mode
Acoustic Mode is intended for persons who are visually impaired. When
Acoustic Mode is turned on, the meter guides you through the testing
process using beep tones; it also announces the test result as a series
of beeps. For more information see Chapter 7.
Visually impaired persons need a sighted person to instruct them
in the use of the meter and to assist them with all aspects of its
operation. Visually impaired persons must not test their blood
glucose without the assistance of a sighted person.
Optimized design
Your Accu-Chek Go meter was designed for ergonomic functionality and
good looks.

1.3 Display features
Throughout these Instructions for use you will see examples of what the
display looks like. Any elements that are shown surrounded by a halo in
this booklet actually flash on the meter’s display.
Example:
You have turned on the meter to perform a blood glucose test. In the
display you see the test strip symbol and blood drop symbol. The drop
symbol is flashing.
Flashing
blood drop symbol
The time, date and blood glucose results shown in the display are
intended only as examples. They will not be the same as those shown
by your meter. The blood glucose meter that is depicted in these Instruc-
tions for use displays blood glucose results in mg/dL (see Chapter 2.2
“Checking the unit of measurement for blood glucose”) and has been
set to 24-hour format (see Chapter 3.2.4 “Setting the time-and-date
format, time and date”). Your meter, on the other hand, may display
blood glucose results in mmol/L and/or be set to 12-hour format.

16 Initial steps before testing
Farbe: P 021 – Prüfmittelnummer: 201
2 Initial steps before testing
2.1 Checking the contents
Check that your monitoring kit is complete. The package contents are
listed on the box.
If anything is missing, please contact your local customer support and
service centre. Contact details are given at the end of Instructions for
use.
2.2 Checking the unit of measurement for blood glucose
Blood glucose results can be displayed in two different units (mg/dL or
mmol/L). Consequently, two different versions of the same meter are
available. Check that your meter displays the unit you are accustomed
to. The type plate on the back of your meter indicates which unit your
meter uses. If you do not know which is the right unit for you, ask your
doctor.
The unit that your meter displays cannot be changed. If the
wrong unit is printed on the type plate, please consult your dealer
or pharmacy. Working with the wrong unit can cause you to mis-
interpret the test results.

drained prematurely. Before using the meter, remove the protective film.
PTurn the meter upside down.
You will see the film projecting from the battery compartment cover.
PSimply pull the film vertically out of the meter. You do not need to
open the battery compartment to do this.
