Luister niet langdurig met een hoog geluidsvolume om mogelijke gehoorbeschadiging te voorkomen. Correcte verwijdering van dit product Het doorgestreepte vuilnisbaksymbool op uw product,batterij,literatuur of verpakking geeft aan dat het product en zijn elektronische accessoires niet bij het huishoudelijk afval mogen worden gegooid.Om uw apparaat veilig te recyclen, gebruikt u lokale retour-en inzamelsystemen of neemt u contact op met de winkel waar het apparaat oorspronkelijk is gekocht. EU-conformiteit met regelgeving Bij deze NOTHING TECHNOLOGY LIMITED verklaart dat de radioapparatuur van het type B181 in overeenstemming is met Richtlijn 2014/53/EU. De volledige tekst van de EU-conformiteitsverklaring is beschikbaar op:https://www.nothing.tech/support/manuals RoHS-nakoming Dit product voldoet aan richtlijn 2011/65/EU en daarbij behorende wijzigingen, met betrekking tot de beperking van het gebruik van bepaalde gevaarlijke stoffen in elektrische en elektronische apparatuur. EU-Contact: Nothing Technology B.V.Jan Pietersz.Coenstraat 7, 2595WP's-Gravenhage,the Netherlands. Europese frequentiebanden en vermogen Maximaal uitgezonden radiofrequentievermogen in de frequentiebanden waarin de radioapparatuur werkt: Het maximale vermogen voor alle golfbanden is lager dan de hoogste grenswaarde die in de desbetreffende geharmoniseerde norm is gespecificeerd. De frequentieban- den en de nominale limieten voor het zendvermogen (uitgestraald en/of geleid) die op deze radioapparatuur van toepassing zijn, zijn als volgt: Bluetooth (2402-2480MHz):<13dBm 151617181920 requires concentration. 5.Do not switch the ear(1) on/off too often as that may cause them to crash and require a reset (by charging). 6.Use the ear(1) in temperature range of 0°C to 35°C and 45% to 75% humidity. Store them in the temperature range of -20°C to 40°C. Too high or too low temperature will degrade quality and may damage the ear(1) and battery.Using the NOTHING ear(1) in a dry environment may cause static electricity and give a weak electrostatic discharge.To minimize the risk of electrostatic discharge, avoid using the NOTHING ear(1) in a dry environment or touch grounded metal objects before using them. 7.The charging temperature range is 5°C to 40°C. Extremely high or low temperatures may prevent the ear(1) from being charged or cause damage to the ear(1) and battery. 8.The ear(1) can be charged with a power cable and power adapter or through a PC. Power adapters must comply with local and national regulations and regional and international safety standards,includ- ing Intern-ational Standard for Safety of Information Technology Equipment (IEC 60950-1/IEC 62368).Using any third-party power adapter that does not comply with the above safety standards may result in injury. Using a damaged power cable or charger or charging the ear(1) in a wet environment may cause a fire,electric shock,inju- ry,or property loss (for example, charging box damage). 9.Some components of the NOTHING ear(1) and the charging box will produce electromagnetic fields. NOTHING ear(1) and the charging box also contain magnets. These electromagnetic fields and magnets may interfere with pacemakers, defibrillators or other medical equipment. Keep medical equipment a safe distance from the NOTHING ear(1)/charging box.Consult your doctor or medical equipment manufacturer to find out more about medical equipment.If you are unsure whether the NOTHING ear(1) and charging box are interfering with your pacemaker, defibrillator or other medical equipment, stop using them. 10.Normally, the Type-C plug and the bottom of NOTHING ear(1) tube will fade, which is normal. Dust, debris, and water inflow may cause this. Before cleaning, take the NOTHING ear(1) out of the box, and disconnect the Type-C-to-USB cable that connects the box to the PC or PC adapter.Use a soft, dry and lint-free cloth to clean the Type-C plug and bottom of NOTHING ear(1) tube. Do not use liquid cleanser. 11.For support and troubleshooting information, user discussion boards, and the latest NOTHNG NOTHING is a registered trademark of NOTHING TECHNOLOGY LIMITED.
