Watch this short video to see how easy it is to set the date and time.

Your meter comes with the batteries already installed and a preset time and date. You may need to change the time to match your time zone or, if you live in a state that observes daylight saving time, to reflect the time change.

To change these settings:

1. Press and release the On/Off button to turn the meter on. The flashing test strip symbol appears. NOTE: If this is the first time your meter has been turned on, it will automatically enter the set-up mode, and "Set-up" and the hour will flash on the display. Skip to Step 3 to change the time or, if the date and time are correct, press and hold the On/Off button to exit the set-up mode.
2. To enter the set-up mode, press and hold the On/Off button for about four seconds. “Set-up” and the hour flash on the display.
3. Press and release the arrows to decrease or increase the hour. Press and hold the arrows to scroll faster.
4. Press and release the On/Off button to set the hour. The minutes flash.
5. Repeat steps 3 and 4 to set the minutes, AM/PM, month, day and year. The flashing field is the one you are changing.
6. Once you set the correct time and date, press and hold the On/Off button until the flashing test strip symbol appears.

Your battery should last for approximately 2,000 tests.

Make sure you have a new 3-volt, lithium battery, number CR2032, to insert. Open the battery door on the back of the meter, remove the old battery for at least 20 seconds, and press any button on the meter. Insert the new battery with the “+” sign facing out. Snap the battery door back into place. Press the on/off button, and the meter will beep. Setup and hour are flashing on the display. If the date and time are correct, press and hold the on/off button for about 4 seconds. Release the button, and you’re done.

The meter uses 1 3-volt lithium coin cell battery (type CR 2032) found in many stores.

The meter includes an additional internal battery that retains the time and date for up to 72 hours. So when the battery is changed, no memory is lost.

Clean the meter to remove visible dirt or other material prior to disinfecting.

• Clean and disinfect the meter at least once per week and when blood is present on the surface of the meter.

• Clean and disinfect the meter before allowing anyone else to handle the meter. Do not allow anyone else to use the meter on themselves for testing purposes.

With the new Accu-Chek Aviva blood glucose meters, it is not necessary to delete stored results. Once 500 blood sugar (glucose) results are in the memory, adding a new result causes the oldest one to be deleted.

No, the meter will no longer provide an automatic warning message telling you that your vial of test strips will soon expire or lock you out once they have expired.

Roche goes above and beyond to deliver safe, accurate and dependable products.
For every lot of Accu-Chek test strips, containing millions of strips, one out of every 100 vials is tested for consistency of performance
Vials representative of the entire lot are tested a second time, some in a lab setting and others with blood from actual people with diabetes to reflect a real-world environment As a result of our quality assurance process, we won’t release affected test strips when any of the samples show a reading outside our accepted limits.

Also, the Accu-Chek Aviva fulfills ISO 15197 : 2013 accuracy standard.

Because your monitor and lab tests don't measure the same thing, these numbers are likely to vary. Lab tests generally test plasma, but a meter uses whole blood. As a result, even if you take both tests at the exact same time, your meter is likely to show a lower number than the lab results. This is perfectly acceptable, and your healthcare professional will already be factoring this in.

The Accu-Chek Aviva meter is not approved for use in clinical settings in the United States and Canada, although the Accu-Chek Aviva meter is cleared to test capillary blood samples.

There are a few ways you can improve blood flow and make blood sugar testing easier: Warm your fingers by washing with warm, soapy water, then rinse and dry completely. Let your arm hang down at your side to increase blood flow to the fingertips. Grasp finger just below the joint closest to the fingertip and massage gently toward tip of finger, then squeeze for 3 seconds. Use an Accu-Chek lancing device set to the right penetration depth for your skin type. Refer to your User's Guide for additional information.
