Answers to Frequently Asked Questions

The sensor can be used for 15 days, and you’ll get a sensor replacement alert five days before it expires. The sensor will be automatically disconnected when it expires, and you will need to replace it. Please read the Instructions for Use on our support page here for further assistance.

Unfortunately, the sensor can’t be reattached after falling off. You’ll need to disconnect it and replace it with a new one.

Check that your smart device's Bluetooth is turned on. If Bluetooth is turned on, refer to ‘What should I do if the app can’t find a signal’ below.

A glucose meter measures the glucose concentration in the blood from the tip of the finger, and the sensor measures the glucose concentration in the interstitial fluid.

It may take time for glucose to reach the interstitial fluid, resulting in a difference in the glucose level.

If current sensor readings do not match symptoms or expectations, use a glucose meter to make diabetes treatment decisions.

Wash your hands thoroughly with soap and water, use your glucose meter to obtain a reading by pricking your finger, and compare the result with your physical condition. Consult your healthcare professional as necessary.

The sensor can’t be used if it doesn't detach properly. Hold the adhesive patch on the sensor and gently remove the sensor from the applicator. If a sensor on an applicator does not detach properly and is not attached in the proper area, it can’t be used.

Attaching the sensor to the skin can cause slight chafing. The degree of stimulation or itchiness can differ according to environment, individual differences, allergic reactions, etc. Try and change the attachment location regularly and see if that helps. If the chafing and itchiness persists, stop using the sensor and consult your healthcare professional.

If you don't hear the app alerts on your smart device, check the following:

• Check your alert settings in the app.
• Check your alert settings and volume on your smart device.

Keep the sensor and smart device as close to each other as possible. Connecting may take up to 15 minutes. If the problem persists after 15 minutes, follow these steps:

• Android: Go to Settings > Applications on your smart device and force restart CareSens Air.
• iOS: Force restart CareSens Air.

Disconnect the sensor on the app, hold the edge of the adhesive tape, and slowly peel it off. Dispose of the sensor after removing it.

When the app is unable to receive sensor glucose readings, the signal icon on the home screen will show ‘Signal loss’, and new glucose readings will not be displayed. The sensor takes and sends glucose readings every five minutes. Any data that hasn't been sent will be stored for 12 hours. It will be sent automatically when the connection is restored.

CareSens Air has passed a waterproofing test at a depth of 1 m for 24 hours (IP48). However, the waterproof performance can change according to the usage environment, and it is best to stick waterproof tape on it for sensor protection when it will be exposed to water for a long time.

The sensor can lose some stickiness after long periods of use. We recommend using sensor tape to prevent this problem. If you do not have any extra sensor tape, you can use regular medical tape. Follow the proper method for attaching the sensor to maintain the stability between the sensor and skin.
