Meter Use and Precautions
 Wait for the Blood Drop / Strip Symbol to appear before applying the sample.
 The meter is pre-set to display blood glucose concentration in either millimoles
per liter (mmol/L) or milligrams per deciliter (mg/dL) depending on which unit of
measure is standard in your country. This unit of measure cannot be adjusted.
 Meter will shut off by itself after 2 minutes of inactivity.
 Do not get water or other liquids inside the meter.
 Keep the strip port area clean.
 Keep your meter dry and avoid exposing it to extremes temperature or humidity.
Do not leave it in your car. Please use the meter indoor.
 Do not drop the meter or get it wet. If you do, check the meter by running a
quality control test. Refer to Quality Control Test on page 19 for instructions.
 Do not take the meter apart. This will void the warranty.
 Refer to the Caring for Your Meter section on page 38 for details on cleaning
the meter.
 Keep the meter and all associated parts out of the reach of children.
Note: Follow proper precautions and all local regulations when disposing of the
meter and used battery.

On Call®Extra Blood Glucose Test Strips
The On Call®Extra Blood Glucose Test Strips are thin strips. The strips have a
chemical reagent system. They work with the On Call®Extra Voice Blood Glucose
Meter to measure the glucose concentration in whole blood. After the strip is
inserted into the meter, blood is applied to the sample tip of the test strip. The blood
is then automatically absorbed into the reaction cell where the reaction takes place.
A transient electrical current is formed during the reaction. The blood glucose
concentration is calculated based on the electrical current detected by the meter.
The result is shown on the meter display. The meter is set to display plasma
equivalent results.
IMPORTANT: Apply the sample only to the sample tip of the test strip. Do not apply
blood or control solution to the top of the test strip. This may result in an inaccurate
reading.
Hold the blood drop to the sample tip of the test strip until the check window is
completely full. The meter will then begin to count down. If you applied blood but do
not see the countdown start, you may reapply a second drop of blood within 3
seconds. If the check window does not fill and the meter starts to count down, then
do not add more blood to the test strip. If you do then you may get an E-5 message
or an inaccurate test result. In this case if the meter begins to count down and the
check window does not fill, discard the strip and begin the test again with a new test
strip.
Sample Tip
Apply blood or control solution here.
Check Window
Check to confirm that a sufficient
sample has been applied.

Storage and Handling
Please review the following storage and handling instructions:
 Store test strips in a cool, dry place at 2-30 °C (36-86 °F). Store them away from
heat and direct sunlight.
 Do not freeze or refrigerate.
 Do not store or use test strips in a humid place such as a bathroom.
 Do not store the meter, the test strips or control solution near bleach or cleaners
that contain bleach.
 The test strip should be used immediately after removing it from container.
 Repeated insertion and removal of a test strip into the meter strip port may
result in reading errors.
 Do not use your test strips past the unopened expiration date printed on the
label. Using test strips past the unopened expiration date may produce incorrect
test results.
Note: The expiration date is printed in Year-Month-Date format. 2020-01-30
means January 30th, 2020.
Special Instructions for Test strip in the Vial
 Test strips must be stored in the original vial with the cap tightly closed. This
keeps them in good working condition.
 Do not transfer test strips to a new vial or any other container.
 Replace the cap on the test strip vial immediately after removing a test strip.
 A new vial of test strips may be used for 6 months after being first opened. Write
the opened expiration date on the vial label after opening. Discard the vial 6
months after you first open it. Usage after this period may result in inaccurate
readings.

Special Instructions for Test Strip in the Foil Pouch
 Tear the pouch carefully starting from the tear gap. Avoid damaging or bending
the test strip.
 Use test strip immediately after removing it from the pouch.
Test Strip Precautions
 For in vitro diagnostic use. Test strips are to be used only outside the body for
testing purposes.
 Do not use test strips that are torn, bent, or damaged in any way. Do not reuse
test strips.
 Keep the test strip vial or the foil pouch away from children and animals.
 Consult your physician or healthcare professional before making any changes
in your treatment plan based on your blood glucose test results.
See the test strip insert for more details.
On Call®Extra Glucose Control Solution
The On Call®Extra Glucose Control Solution contains a known concentration of
glucose. It is used to confirm that your On Call®Extra Voice Blood Glucose Meter
and On Call®Extra Blood Glucose Test Strips are working together properly. It also
confirms that you are performing the test correctly. It is important to run a quality
control test regularly to make sure you are getting correct results.
You should run a quality control test:
 Before you first use your meter, to familiarize yourself with its operation.
 Before using a new box of test strips.
 When you suspect that the meter or test strips are not working
properly.
 When you suspect that your test results are inaccurate, or if they
are inconsistent with how you feel.
 When you suspect your meter is damaged.
 After cleaning your meter.
 At least once a week.
Refer to Quality Control Test on page 19 for instructions on running a quality
control test.

Storage and Handling
Please review the following storage and handling instructions:
 Store the control solution at 2-30 °C (36-86 °F).
 Do not refrigerate or freeze.
 If the control solution is cold, do not use until it has warmed to room temperature.
 Use before the unopened expiration date that is shown on the bottle.
Note: The expiration date is printed in Year-Month-Date format. 2020-01-30
means January 30th, 2020.

Record the opened and the resulting expiration date on the bottle label.
Control Solution Precautions
 For in vitro diagnostic use. The control solution is for testing only outside the
body. Do not swallow or inject.
 Shake well before using.
 Control solution tests are designed to be accurate only when tested between 10
and 40 °C (50-104 °F).
 The control ranges shown on the test strip vial (or on the foil pouch) are not
recommended ranges for your blood glucose level. Your personal blood glucose
target ranges should be determined by your diabetes healthcare professional.
 Do not touch the test strip with the tip of the control solution bottle.
 Use only the same brand of control solution that was provided with your kit.
See the control solution insert for more details.
