FAQ Listing

The system automatically detects when enough blood has been applied to the test strip and begins the test, even if some yellow is still visible. The only time you need to apply more blood is when the blood drop symbol continues to flash in the display.
An E4 displays on the meter, indicating not enough blood was drawn into the test strip for measurement or blood was applied after the test had started. You should discard the test strip and repeat the blood sugar test.
No. Although you can insert a code (activation) chip from another meter into the Accu-Chek Aviva Nano blood glucose meter, you will get an E-2 error message
No, check the use by date on the test strip container. Do not use test strips past the use by date.
A control test using your meter's specific control solution ensures that the meter and test strips are working properly. Testing with control solution is just like a blood sugar test, except you fill the window on the test strip with a drop of control solution instead of blood.
Performing a control test lets the user know the meter and test strips are working properly. Perform a control test when:  You open a new test strip box  You left the test strip container open  You think the test strips are damaged  You want to check the meter and test strips  The test strips were stored in extreme temperatures, humidity, or both  You dropped the meter  Your test result does not match how you feel  You want to check if you are performing the test correctly
The Accu-Chek Aviva Nano blood glucose meter automatically recognizes Accu-Chek Aviva control solutions, so running a control test is easier than ever. First, wipe the tip of the control bottle. Then put the meter on a flat surface, insert the test strip, and squeeze a drop of the control solution onto the front edge of the test strip. A result appears with a flashing “L”. Press one of the arrow keys once to indicate a Level 1 control test or twice to indicate Level 2. Press the ON/OFF button to set the level in the meter. The control result and “OK” alternate in the display if the result is in range.
If the control solution evaporates or concentrates on the tip of the bottle, it could cause the meter to display an incorrect control reading.
Control test values do not stay in the memory that you can access on the meter. Instead, the meter stores them in the downloadable memory, so you can view them with supported software.
Control solutions are good until the expiry date, unless they are opened. Once they have been opened for use, the control solutions are good for 3 months.
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 province that observes daylight saving time, to reflect the time change. Press and release the On/Off button to turn the meter on. The flashing test strip symbol appears. Press and hold the On/Off button again until "set-up" appears in the display. Press and release the arrows to decrease or increase the hour. Press and release the On/Off button to set the hour. The minutes flash. Repeat steps 3 and 4 to set the minutes, AM/PM, month, day and year. The flashing field is the one you are changing. Once you set the correct time and date, press and hold the On/Off button until the flashing test strip symbol appears
Make sure you have two new 3-volt, lithium batteries, number CR2032, to insert. Open the battery door on the back of the meter, remove the old batteries for at least 20 seconds, and press any button on the meter. Insert the new batteries 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 2 3-volt lithium coin cell batteries (type CR 2032) found in many stores.
The meter includes an additional internal battery that retains the time and date while you change batteries. However, you'll still want to confirm that the time and date are correct.
An additional internal battery supports the clock when the main battery is removed. You can leave the battery out of the meter for up to 72 hours and still retain the time and date. If you replace the battery within that time, the meter will ask you to verify the time and date the next time you turn it on. When you replace the main battery, the internal battery will automatically recharge. If you do not replace the battery within 72 hours, the meter will retain the time and date that was stored immediately before the internal battery was depleted.
Some countries share meter configurations with other countries, have multiple time zones within their country, and/or change their time semi-annually. Therefore, manufacturing is unable to set the correct time for every country. The system directs you to confirm the time and date the first time you turn it on, and the default time should be within 1–2 hours of your correct time.
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.
Cleaning is simply removing dirt from the meter, while disinfecting refers to removal of most but not all, disease-causing and other types of microorganisms.

Marking results with a pre-meal or post-meal marker can provide more information about how food affects your blood sugar, to aid in managing your numbers. You can also use a general marker to identify an alternate site test or post-exercise result. When you review the results in memory, these markers can help you remember what was different about the result. To use a marker: When you perform a test you want to mark, do not remove the test strip. Press and release the right arrow key to toggle through the marker options. When you mark a pre-meal result, you can opt for a post-meal test reminder. The meter can beep 1 or 2 hours after you test to remind you—choose your preference in the set-up mode. When the marker you want to use appears, remove the test strip from the meter. Refer to your User Manual  for more details.
You can set up to 4 test reminders per day, in 15-minute increments. At the set reminder time(s), a series of beeps will sound every 2 minutes, up to 3 times per reminder. The reminder beep will not occur if the meter is on at the set time, or if you run a test within 15 minutes of the set reminder time. If you turn on the meter while the reminder is sounding, the series of beeps for that reminder will stop.
Once set, test reminders will beep every 2 minutes up to 3 times. It will turn off when you insert a test strip or press any button. To turn the beeper off all the way, refer to the set-up instructions in your User Manual .
You can transfer stored results to a computer simply by pointing the infrared (IR) window on top of the meter toward the IR window of the Accu-Chek download cable.

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 Nano fulfills ISO 15197 : 2013 accuracy standard.

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.
It's a small sample—just 0.6 microliter.
The Accu-Chek Aviva Nano blood glucose meter will test blood samples from 3 alternate sites (called Alternate Site Testing, AST): forearm, palm, and upper arm.
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.
