• The battery is empty or there is no battery in the meter. Insert a new battery. You will need one CR2032 type battery
• You have inserted the battery the wrong way round. Remove the battery and place it in the battery compartment as shown in the manual.
• The temperature may be too low. Ensure that the ambient temperature is +8 to +42 °C (+46.4 °F to +107.6 °F)
• The meter may be defective. Contact Us.

• The code chip has not been correctly inserted into the meter. Remove the code chip and re-insert it.

• You slid a used test strip into the meter.
• You applied blood or control solution to the test strip too soon, i.e. before the drop symbol flashed on the display.
• Start the blood glucose test from the beginning with a new test strip.
• The measurement window is dirty. Clean the measurement window.

Your blood glucose value may be very low. If you have typical symptoms of a very low blood glucose, immediately follow your healthcare professional’s instructions for such cases. Repeat the test afterwards.

• You removed the test strip from the meter in order to apply blood and did not slide it back in it within 20 seconds.
• The test strip was bent or moved while testing was in progress.
• You applied too little blood or control solution to the test strip.
• You waited too long before applying a second drop of blood or control solution. Start the blood glucose test from the beginning with a new test strip.

While the test was in progress, you connected the meter to a computer that was on. Remove the USB cable and repeat the test.

The meter was exposed to a strong electromagnetic field. Change your position or turn the source of electromagnetic radiation off.

The meter is exposed to too much light. Go to a shaded place or shade the meter, for example with your body.

Do not perform a test when the meter and the test strips are exposed to direct sunlight. Go to a shaded place or shade the meter, for example with your body.

• If the meter is exposed to too much light, the meter does not allow any tests to be performed. In this case the following error message appears on the display.

You removed the code chip while testing was in progress. Re-insert the code chip into the meter. Repeat the test with a new test strip.

A meter error has occurred. Start again from the beginning. If the error message appears again, the meter is defective. Please contact us.

The meter is connected to a computer (PC). Once the connection to the computer has been successfully established, the meter transfers all saved test results. During the data transfer, does not flash. The test results remain in the meter’s memory after being transferred.

The required USB cable is a standard Micro-USB cable available from most electrical retailers; the meter kit does not include a standard Micro-USB cable.  For more information please contact us.

The meter has been disconnected from the computer (PC). This is displayed for approximately 3 seconds. The meter turns itself off.

Averages cannot be calculated because

• you have not set the time and date,
• only test results without a time and date are saved,
• only test results that are not included in the calculation are saved, e.g. results from control tests,
• no test results were saved in the period in question, e.g. all test results in memory are more than 7 days old,
• the chronological order of the test results in the memory has been interrupted.

The ambient temperature or the temperature of the meter is too low or too high for a test. Tests cannot be performed at temperatures below +5 °C and above +45 °C. Ensure that the ambient temperature is between +8 and +42 °C and wait for the meter to adapt to that temperature.

Your meter measures blood glucose within a defined range (0.6–33.3 mmol/L or 10-600 mg/dL).

The display may indicate that your blood glucose is lower than the measuring range of the system (0.6 mmol/L or 10 mg/dL).

Follow the relevant instructions given by your healthcare professional for possible hypoglycemia. Immediately and repeat the test.

If this does not match how you feel, please contact contact us.
