The BioSense optical wrist heart rate monitor will occasionally emit green light and flashes. Consult with your physician if you have epilepsy or are sensitive to flashes of light. Always consult your physician before beginning or modifying any routine or exercise program. The device, accessories, heart rate monitor and related data are intended to be used only for recreational purposes, not medical purposes, and not intended to diagnose, monitor, treat, cure or prevent disease. The heart rate readings are for reference only, and no liability is accepted for the conse-

quences of anywrong interpretation. Although the optical wrist heart rate monitor technology typically provides an accurate data for users heart rate, there are inherent limitations with the technology that may cause some of the heart rate readings to be inaccurate under certain circumstances, including the users physical characteristics, installation of the device and type & intensity of activity. The activity trackers rely on sensors to track your movement and other metrics. The data and information provided by the device are intended to assess your activity and metrics closely, but may not be completely accurate, including the data for steps, sleep, distance, heart rate, and calories. Do not immerse or expose batteries to water or other liquids. Do not expose the device to a heat source or in a high-temperature location, for example, in an unattended vehicle in the sun. To avoid the possibility of damage, remove the device from the vehicle or store it out of direct sunlight, such as the glove box. Do not operate the device outside of the temperature ranges specified in the printed manu-

al, which are included in the products packaging. When storing the device for an extended time period, please store within the temperature ranges specified in the printed manual which included within the products packaging. Do not use a power and/or USB cable that is not Approved or supplied by the manufac-

turer. Please use within the temperature ranges specified in the printed manual which included in the produci packaging. 7 BioSense health band Legal disclaimler Some measurements require the installation of HELO Smart App available for An -
