How to pair your device to a sensor

1. Login to the CareSens Air user app on your smart device and tap ‘Safety Information’, then tap ‘Scan Sensor Information’.
2. On the 'Scan Sensor Information' screen, scan the barcode on the package label, or enter the barcode manually by tapping ‘Enter Manually’. Be sure to enter the information exactly as it appears on the sensor package label. If you enter the serial number and pin code incorrectly, the sensor will fail to connect.
3. Follow the steps on the screen to attach the sensor on the back of your upper arm, and tap ‘Start Pairing’. You’ll find more details on attaching the sensor below.
4. To connect the sensor, press the power button firmly until it is recessed. When the sensor is successfully connected, the alert settings screen appears. In the case of iOS, you will need to enter the pin code to connect to Bluetooth.
5. Once you finish configuring the alert settings, the sensor will warm up for 30 minutes.
6. After the 30-minute warmup, your glucose readings will appear on the screen. You don’t need to calibrate the sensor, but you can choose to do so if required.

1. Wipe the area where the sensor will be attached to the skin with an alcohol swab and wait for it to dry completely.
2. Remove the safety cap and place the applicator horizontally on the back of your upper arm, where the sensor will be attached. Do not press the release button on the applicator until you are ready to attach the sensor.
3. Press the Release button on the applicator. The sensor will be released from the applicator and can be attached to the back of your upper arm.
4. Remove the applicator and make sure that the sensor has been properly attached.
5. After attaching the sensor, you can attach sensor tape to prevent the sensor from being easily removed from the attachment area.

1. Set your glucose levels in ‘Settings’. 
2. Under ‘System Alerts’, you can choose whether to receive alerts such as calibration, signal loss, remaining sensor life, sensor error.
3. Set to ‘Mute’ as needed, which will silence all alerts except for essential alerts. Calibration, signal loss, remaining sensor life, sensor error alerts must be separately muted to stop the alerts from sounding.
