Always apply the body-side adhesive patch to clean, dry, and hair-free skin. Avoid touching the sticky side when applying the patch to the sternum and press the edges firmly to ensure it adheres fully. 

To help the patch last longer, gently pat it dry after showering rather than rubbing it. The patch is designed to be sweatproof and waterproof, but excessive friction can reduce its effectiveness. If the adhesive comes off, do not attempt to reattach it. 

When removing the patch, peel it away gently. Any remaining adhesive residue can be washed off with warm, soapy water.  

For the device-side patch, keep it free from lint and fibres, as buildup can reduce how securely the device attaches. Replace it if it becomes less effective and take care not to cover the metal contacts when applying a new one.
