Applying the sensor patch Identify the sensor patch location on the body. For the best signal, the sensor patch should be applied to the middle area of the chest (see image below). For patients with developed breasts, place the sensor patch a little higher on the chest. Before applying the sensor patch, clean the skin with an alcoholic swab and let the skin dry completely.
Attach the sensor patch with adhesive to the chest 1. Peel off the paper cover labelled (2) from the adhesive. 2. Attach that side of the adhesive to the upper middle chest region and press firmly to secure the sensor patch.

The smartphone with the Leo mobile application is not required to be connected to the sensor patch during this time.
Tap the Download button and follow the steps to download the data. During the data download, the phone must be left close to the sensor patch, and the Leo mobile application must not be closed or minimized.
Once the download is complete, the data will be automatically sent to the cloud for processing. A push notification will be sent in the mobile application once the data report is available in the History tab on the mobile app. Removing the sensor patch The following steps are to be performed by the patient if aged 12-21 years or by the patient's parent or caregiver for patients under 12 (or if assistance is otherwise needed).
Remove the adhesive from the sensor patch Peel the used adhesive from the sensor patch and clean the sensor patch with alcoholic wipes. The adhesive is single-use and should be discarded after single use. If the sensor patch is to be used again, install one of the provided new replacement adhesives using the steps above.

Quality of service Bluetooth® Wireless Technology uses several low-level data handling techniques to ensure the integrity of data transmission to and from the sensor. Additionally, the sensor patch uses its own, higher-level data handling measures to ensure that signals are received accurately. If the sensor patch is not able to establish a reliable wireless connection for any reason, it has been designed to internally record data for automatic retransmission when a reliable connection can be established.
