Uptivo Belt is composed of a heart rate sensor and an elastic band with conductive electrode components. Detach the sensor from the strap after every use in order to prevent moisture or sweat from keeping the conduction active and the sensor on. You can clean the sensor with a solution of mild soap and water, if needed. Do not use alcohol or abrasive products to clean it. Dry the sensor before you store it in a case or in a pocket of your gym bag. Gently hand wash the strap with a solution of cold water and mild soap. Don’t use any other kind of moisturizing solutions to wash it. Once in a while, you can use a solution of water and baking soda to remove bad smell. Don’t let the strap soak and don’t bend the conductive components and electrodes. Store the sensor and the strap separately in a cool and dry place to optimize battery life. Do not expose Uptivo Belt to direct sunlight for extended periods of time.
