Sunsense AS Technical User Manual SunSense Pro 1 Technical User Manual 2022 SunSense Pro Sunsense AS Technical User Manual SunSense Pro 2 Disclaimer The SunSense Pro UV tracker and accompanying App is a tool to help you enjoy the sun responsibly during the day. It is designed by SunSense AS, No rway. By using the SunSense Pro UV tracker and App, you acknowledge that you have read, understood, and accepted the terms and conditions in this disclaimer. For information on the privacy policy and GDPR compliance, please refer to the terms listed in the SunSense App. The SunSense Pro UV tracker and App is not a replacement for public and/ or individual health advise concerning your sun behaviour. The SunSense Pro UV tracker and App should not be used for infants and young children below 3 years, as these should be kept out of direct sunlight. Use the SunSense Pro UV tracker and App to help plan your daily activity in the sun to reduce UV exposure and avoid skin damage. The SunSense App uses the global/local forecast UV index available from the Danish Meteorological Institute (DMI)/EUMETSAT/O3MSAF and calculates via different algorithms a timeframe for you to stay in the sun (with or without a SPF sun protection applied). All UV index forecasts have inaccuracies because they are predictions. The recommendation given by the app is based on your age, skin type, environment (i.e. beach or land), and your available SPF sun protection. In addition, your location – either obtained from the GPS software of your mobile phone or from information, which you provide – is used to plan your day in the sun. The SunSense App recommends you to seek shade, to wear sunglasses, clothes, or a wide-brim hat, based on your activity and applied SPF sun protection to reduce UV exposure. The SunSense App will remind you to reapply sunscreens depending on conditions and skin type. Factors that can influence your personal UV exposure include, but are not limited to, number of hours in the sun and reflections from your surroundings can change during the day. The amount of sun protection applied can also be lower than recommended from the manufacturer. Thus, the recommendations given in the SunSense App should only be used as a guideline, and should not replace good sun behaviour. Also, how the UV tracker is attached to the body or clothes and its orientation relative the sun will influence the actual UV exposure readings. Dirt, and in particular sunscreen on the UV tracker sensor window can significantly influence the measurements negatively. When used without the SunSense UV, the SunSense App does not measure the actual amount of accumulated UV radiation exposure. Use the SunSense UV tracker as directed to measure your actual and accumulated UV-exposure. Always follow the instructions for proper use of the SunSense UV tracker. The SunSense App and SunSense UV trackers are not scientific instruments. They are health and fitness products and should not be used to diagnose, treat, or monitor any medical conditions. SunSense AS do not accept any liability for any injury, loss, damage, or costs incurred, or any consequences resulting directly or indirectly by use of or the reliance on the information from the SunSense Pro UV tracker and the App. Sunsense AS Technical User Manual SunSense Pro 3 FCC compliance statement FCC ID: 2AZRL-SNSCBT This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause interference. (2) This device must accept any interference, including interference that may cause undesired operation. User Information acc. to FCC15.21 Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. FCC Class B Statement for Digital Devices This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/television technician for help. Sunsense AS Technical User Manual SunSense Pro 4 Introducing SunSense Pro Take UV protection to the next level with the advanced SunSense Pro wearable UV-sensor with Bluetooth connectivity and a smartphone app. Configure the app with your personal profile and skin type, and it how long you can stay in the sun conditions at your location and if necessary tell you when to apply sunscreen. The app will display updated UV- and weather forecasts. Multiple sensors can be connected to the same app and smartphone, and alarm levels are set individually. Easy access to user manuals and other information. The sleek and convenient size of just 23×5 mm together with a variety of wearing accessories means the sensor device can be comfortably worn on a suitable place on body or clothing where it will track your accumulated UV-exposure during the day regardless of how you move in and out of the sun and shadow, shifting cloud conditions, pressing heat or cooling breeze. SunSense will tell you your actual exposure status and warn you whenever you approach your recommended maximum levels. The…
