Whatever type of Accu-Chek meter you have, cleaning and disinfecting are important for good maintenance.

While cleaning is simply removing dirt from the meter, disinfecting refers to removing as much of the disease-causing microorganisms and other germs as possible.

When to clean and disinfect your Accu-Chek Meter:

You should clean and disinfect your meter once a week, or any time blood gets on it. You should also clean your meter before allowing anyone else to handle it.

What to use when cleaning and disinfecting your Accu-Chek Meter:

Super Sani-Cloth® disposable pop-up wipes are a convenient way to kill germs, and have been approved for cleaning and disinfecting the meter. You can buy them online from Amazon.com, Office Depot, Walmart and other retailers.

The parts of your Accu-Chek meter you should keep clean:

Be sure to clean the areas around slots and openings, while being careful not to get any moisture in them.

You should also wipe down the entire meter surface, including the meter display.

All information is saved when you change the batteries of any Accu-Chek meter, including the memory, your logbook data, test results, diary information and settings, however you should check that the time and date are correct when you’ve inserted new batteries.

There’s no need to manually code any of our meters. You can discover more detailed information below.

Accu-Chek Guide Me, Accu-Chek Guide, Accu-Chek Guide Link, Accu-Chek Aviva Connect, Accu-Chek Nano and Accu-Chek Compact Plus meters

Follow the steps below to pair your Accu-Chek Guide Me, Accu-Chek Guide or Accu-Chek Aviva Connect meter to the mySugr app:

1. If you are using an Apple device, make sure Bluetooth® is turned on.

a. Bluetooth should turn on automatically for Android users at the beginning of the pairing process.

2. Ensure Location Services are turned on for the mySugr app during the pairing process. (You can turn it back off once you're done. Settings > Apps > mySugr > Location Services.)
3. Open the mySugr app and go to the “Connections” tab in the bar menu located at the bottom of the screen.
4. Select your meter — Accu-Chek Guide Me, Accu-Chek Guide or Accu-Chek Aviva Connect — and follow the steps on the screen to activate it.

Choosing the right Comfort Dial setting:

The most comfortable setting of your Accu-Chek FastClix lancing device will depend on a few things:

1. Whether you're using a fingertip or alternate site.
2. Your skin type – softer, thinner skin requires a shallower setting than thicker skin.
3. The required blood sample – the more blood you require, the higher the setting you'll need.

Start with a low setting, such as penetration depth 2, when using the device for the first time. Dial to a higher setting until the blood volume is right.

Keep in mind, it’s best to always talk with your healthcare professional before deciding if alternate site testing is right for you.

Using your Accu-Chek FastClix lancing device:

1. First, you will need an Accu-Chek FastClix lancet drum and device. Each drum contains 6 pre-set lancets.
2. Remove the cap from the lancing device.
3. Insert the drum, white end first, ensuring to push it all the way in.
4. Do not remove the drum until you’ve used all 6 lancets, as you cannot put it back in once you remove it.
5. Now place the cap back on your lancing device.
6. Set the penetration depth by turning the dial to match your individual skin type.
7. To use the device, simply place the device up against your finger and press the button on top all the way down.
8. After each test, refresh to a new lancet by pushing the white lever back and forth once.
9. The number in the display tells you how many lancets you have left to use before you need to replace the drum.

This video gives visual instructions on how to set up, load and use the Accu-Chek FastClix lancing device.
