1. Before using the Frontier X3 for the first time, locate the black plastic protective inserts inside the metallic electrode socket on the strap. You will need to remove these inserts for optimal performance.
2. Align the electrodes on the Frontier X3 with the sockets on the strap and firmly press together until you hear a click.
3. Apply some water on your skin and the shiny electrode patches on the strap, to ensure good contact during your workout. Dry skin (typically in cold weather) reduces the conductivity of the skin.
4. Wear the strap while ensuring that the button of the device is facing down, and the device is located right in the middle of your chest. When worn on the chest, the strap should feel tight, but not uncomfortable. Make sure that the shiny electrode patches on the undersurface of the strap are in contact with your skin.
5. If the weather is cold and dry, and if you are wearing a shirt not made of cotton, please spray some anti-static on the strap and on the inside of your shirt, after you are wearing your Frontier X3.
6. Start your recording from the app, or by double-clicking the blue button on the Frontier X3.
