Step-by-step guide to applying the sensor 

The Accu-Chek SmartGuide sensor must be placed on your skin correctly for continuous, accurate glucose readings.

Before you apply the sensor

To get the longest wear time for your new sensor, make sure your skin is fully prepared.

  • Always have alternative methods for testing your glucose available. If you lose your mobile device or in case of a system malfunction, switch to an alternative method for testing your glucose, like a blood glucose meter.

Step 1

Select the back of your right or left upper arm to apply the sensor. If the application site is hairy, shave it. Disinfect the application site with an alcohol wipe to ensure clean, oil-free skin, and let it air dry completely.  Stay at least 7.5 cm (3 inches) away from insulin injection sites. Avoid recently used application sites, as well as scars, stretch marks, liver spots, lumps, or blood vessels.

Step 2

Take a close look at the packaging and product to ensure they're not damaged or tampered with. If the pull tab is sticking out before you use it, the sterile barrier is broken. Discard the damaged product and grab a new sensor. Slightly flip the pull tab (A) open. If the pull tab has already been opened before use, discard the device and use a new one.

Step 3

Do not press on the device. Turn the twist cap (B) to open the sterile barrier. You will feel a slight resistance and hear a cracking sound. Pull the twist cap from the applicator (C).

Don’t touch the needle inside. Don’t put the blue twist cap back on after you have removed it, and don’t discard it yet.

Step 4

Place the hand of the disinfected arm on your opposite shoulder. This helps to tighten the skin. Reach under your arm and place the applicator (C) on the application site. Hold the applicator by the external housing. Make sure the entire bottom of the applicator is flat against your skin and press down firmly.

Step 5

Remove the applicator in the same direction without rotating or wiggling it. Swipe over the adhesive pad firmly with your finger to make sure the adhesive pad is properly attached.

You can wear the sensor for 14 days.
